Motion Control – Case Study: Wearable Pumps!

motion control miniature ball screwsThe Next Generation of Intelligent Balloon Catheters Depend on Novel Designs of Ball Screw Driven Pumps

Woburn, MA –Motion Control Components Ball Screws – Case Study –

Situation:

In the realm of cardiovascular assist devices, recent developments have focused on fully implantable pumps. Among the first was HeartMate, quickly followed by Impella and HeartWare. Fully implantable devices are very expensive to develop and produce. Plus they are limited to patients who can tolerate the highly invasive procedure.

A key development in cardiovascular assist devices would be to combine the less-invasive approach of implantable balloons and external pumps with the high portability and reliability of fully implantable systems. This advance would allow the treatment of a much wider range of patients and conditions. A Steinmeyer customer set out to develop an innovative pump to achieve this advance in an intra-aortic system

 

Challenge:

One of the main technical challenges to this approach is designing a wearable pump that can carefully control the balloon’s pressurization. The pump must meet a demanding combination of performance requirements, including:

  • Precise control of pressure
  • Reversible pressurization
  • Light weight
  • Compact size
  • Quiet operation
  • Continuous performance for at least one year

Meeting these requirements was a significant challenge for their engineers. They built and tested early prototypes using traditional designs such as diaphragm pumps. But this approach required separate chambers for positive and negative pressure. The resulting systems were far too large and heavy. So they were forced to find a new approach.

Results:

Their main innovation was selecting a precision ground ball screw as the drive mechanism and pairing it with a custom engineered metal bellows as the pressure chamber. Ball screws deliver exceptional thrust density while enabling high linear acceleration in both the forward and reverse directions. Surrounded by the bellows, this results in an extremely compact and quiet design. Ball screws are also known for their high efficiency (>90%), smooth operation, and long life. Their efficiency enables the use of small motors and low power consumption, which in turn reduce the size and weight of the entire system.

The engineers turned to Steinmeyer to ensure the smoothest running, highest quality ball screw. And they also knew that Steinmeyer was extremely well-qualified to provide technical support through all stages of development. Their system is meeting all of its design requirements and will soon enter late stage clinical trials.

Future:

There is an emerging trend in the development of balloon catheters to serve cardiovascular applications. Intelligent balloon catheters may one day be key to innovation. These devices will use flexible sensors and electronics along the catheter for data collection and therapeutics. They will also incorporate balloons to apply mechanical force in the heart and arteries. Ball screw driven pumps will support these future systems as well.

automation motion control - brushed motors

Fall River, MA — Automation Motion Control – Application – Driver assist systems can help save lives by alerting driver of potential danger!The majority of traffic accidents are caused by human error. In the future, computer-controlled cars will significantly reduce the number of such accidents. Driver assist systems, such as adaptive cruise control (ACC), brake assist systems, or lane departure warning systems (LDW), can save lives. Lane departure warning systems warn the driver if the vehicle is drifting out of its lane. The LDW determines the vehicle’s position in the lane with the use of various optical sensor systems and computers. If the car is in danger of drifting out of the lane, the system activates an electric motor in the steering wheel that causes the wheel to vibrate, warning the driver.

A luxury car manufacturer has engaged maxon to supply the motors for this application. The base DC brushed motor is maxon’s A-max 16 (precious metal brushes, 2 W), modified for the application with an eccentric weight and a specified bearing. In order to prevent the other vehicle systems from being affected by the electromagnetic fields of the motor, it has been equipped with special EMI suppression for automotive applications. The small drive system must meet specific requirements: It needs to be low-noise, dynamic, feature high power density, and fit in a narrow space – requirements that maxon’s small A-max 16 easily masters..

How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?

Motion Control – Application

Easily …   … Using Custom made LM76 Jet Rail Bearings and Shafting!

When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.

 

The main reactor, the fusion containment chamber that is capable of containing a plasma medium of 10 to 15 million degrees is made of non-magnetic stainless steel as are many of the components. The Plasma Medium could be described as a football shaped blob about 1 meter in diameter by 2 meters long. The plasma medium is injected from each end of the reactor assembly by Plasma Guns.

In addition to supporting the weight of the components, the bearings selected to move these massive loads during the construction and testing of the fusion reactor would have to be non-magnetic. Working with engineers, LM76 developed a custom 3 inch Jet Rail Bearing designed to carry both the weight of the fusion reactor and the high energy particle generators. In addition LM76 supplied precision ground, 3 inch 303 stainless steel (non-magnetic) shafting.

The custom manufactured Jet Rail Roller Blocks and 303 stainless steel shafting simplified the assembly/disassembly of the fusion containment chamber and components while ensuring critical alignment throughout travel.

This breakthrough fusion reactor is still in the experimental stage. A commercially viable reactor would need to contain 100 million degrees. Why is the project so important? Because in addition to producing sustainable energy, its only by-product is, environmentally safe, “helium ash.”.

Motion Control Application – Twenty-twenty Vision – Maxon Components Allow Surgeon to Not only See But to Feel!

Motion Control – Application

While robotic assistance systems are available for most types of surgery today, eye surgery used to be an exception. A Dutch company has changed that. A world first in eye surgery.

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Worldwide, about 50 to 70 million people are suffering from visual impairment due to disorders of the retina. Adequate treatment is still impossible in many cases. Eye operations are always a big challenge for a surgeon, and steady hands are a key requirement. Surgeries like those for treating a detached retina require extreme precision. And when it comes to precision, human hands can’t hold a candle to robotic systems.

Ten to twenty times better precision

This is why the company Preceyes, which originated as a spin-out from the University of Eindhoven (Netherlands), has developed a completely new robotic system for eye surgery. Specially designed for the treatment of retina disorders, the assistance system improves precision by a factor of 10 to 20 compared with the human hand. This allows operations to be performed that are currently impossible due to lack of precision – an enormous gain for patients, but also for surgeons, whose effectiveness and accuracy will be vastly improved

motion control haptic robotic component

The new robotic system is used in surgery to treat disorders of the retina. Image © Preceyes

The world’s first robot-assisted operation inside the eye was performed successfully at the John Radcliffe Hospital, Oxford. “This is the culmination of 10 years of work. The ease with which Professor MacLaren was able to perform the surgery is an important step ahead for robot-assisted eye operations and a clear vindication of our technology,” says Marc de Smet, MD Chief Medical Officer at Preceyes.

Haptic feedback

The functional principle is straightforward: While the operating surgeon is sitting next to the patient’s head looking through a microscope, he is operating a joystick whose motion is transmitted to a robotic arm (slave). The robot downscales the motion: When the surgeon moves the joystick by a centimeter, the tip of the robotic arm moves only by a millimeter. Meanwhile, the other hand performs manual tasks as required. The system is designed to allow surgeries to be performed with motion control alone as well, using two joysticks and two robotic arms..

In addition to a haptic feedback function that not only lets the surgeon see but also feel his actions, the robotic system also supports quick retooling. This is an important factor because it reduces the time required for an operation. The motions of the robotic arms are performed by high-precision drive systems of maxon.

Motion Control Application – Implantable medication delivery systems: Where every microliter counts!

Motion Control Application –

Implantable medication delivery systems can have a decisive influence on the quality of life of the patients. In many cases, such delivery systems are vital for the survival of the patients – the systems have to be absolutely reliable. maxon motor manufactures high-precision micro drives for medication delivery systems.

Maxon Logo

motion control application - implantable pump

Fall River, MA — Motion Control Components Application – Patients that suffer from chronic pain, metabolic disorders, diseases of the central nervous system and tumor diseases require accurately dosed medication. Here implantable medication delivery systems are used. Through the localized medication delivery, the dosage can be reduced to the required minimum. These infusion systems thus improve the quality of life of the patients. For many patients, it is only the medication delivery system that allows them to have a life outside of the clinic. Repetitive invasive, painful operations can be avoided. The risk of medication dependency and undesired side effects are reduced to a minimum. All these factors can contribute to the disease no longer being the central focus of the patient’s life.

For example, an active implant is implanted in the lower abdomen directly underneath the skin, where it delivers the medication dosage, programmed by the physician, to the body at the defined times of the day. The implantable unit has a wireless data interface to a patient interface by which the dosage can be adapted at any time. At regular intervals, the internal medication reservoir can be refilled by a specialist. The life span of the active implants measures many years and is limited only by the life of the battery. The core of the active implant is a piston pump manufactured by maxon medical, which specializes in medical technology and is a division of the maxon motor Group. However, the micro drives for implantable medication delivery systems are not comparable with customary maxon motors. In a customary motor, rotary motion is generated and yields torque and speed of rotation.

maxon miniature piston pump

The reciprocating piston pump generates a linear movement that results in liquid pumping. The individual parts of the pump have very narrow tolerances and allow the pump volume to be adjusted with a precision of less a microliter per piston stroke.

As active implants are in direct contact with human tissue, biocompatible materials are an absolute requirement. Therefore, in most cases, titanium is used for the implants. Machining of titanium, especially safe and reliable laser welding, requires a very high level of expertise. Special testing and quality methods, such as inspecting the penetration depth, microhardness and density of the weld seams, are established procedures at maxon medical. The customer requirements on the product are thus fulfilled and the reliability and constant quality of the manufacturing processes are guaranteed. The entire assembly of the implantable micro drive takes place under cleanroom conditions.

maxon medical – Specialist for medical drive solutions and active implants

maxon medical specializes in the manufacturing of medical drive solutions for active implants. The division received ISO 13485 certification in December 2008. The quality management system and the project organization ensure safe, reliable and standard-compliant products and provide the customer with a sound basis for statutory approval of the final products.

Professional project organization and a proven risk management system allow efficient implementation of customer projects. Strict maintenance of statutory requirements has top priority in the implementation of medical technology projects with risk class IIb + III. Production processes, production systems and testing systems always fall under GMP (Good Manufacturing Practice, Commission Directive 2003/94/EC), regardless of the classification of the product.

maxon medical meets highest customer requirements – from selection of suitable suppliers to multi-tier quality control, from the individual parts to the final product. Manufacturing processes in the field of medical technology have very high documentation requirements during the entire value-added chain. All the way from the project idea to series production. In the end, a comprehensive and detailed documentation of all processes is required, including verification of process capability and traceability right back to the individual parts. This process control, matured to the last detail, characterizes maxon medical. It is an important and indispensable component of the entire production process and guarantees the high quality of the micro drives used for active implants of maxon medical.

Motion Control Application – Maxon Drives Power – Hull Cleaning Robot for Large Ships!

Motion Control Application – Specially designed robotic crawler navigates around the underwater portion of a ship to remove the biofilm layers that accumulate there. As a battery operated, autonomous vehicle, component selection made up a highly critical part of the design and manufacture.
motion control - maxon motor

Fall River, MA — Motion Control Components Application – Toxic paint is used on the bottoms of large ships to prevent fouling, which is when a biofilm layer develops, decreasing the ship’s efficiency in moving through the water. The toxic paint continually leeches copper and other heavy metals into the underwater environment as well, causing damage to the organisms that live there. To further complicate the matter, the paint must be blasted off and replaced every 5 to 10 years, at which time literally tons of toxic waste is produced and needs to be disposed of. A ship that operates with a clean underwater surface free from fouling—even thin biofilm layers—will operate so much more efficiently that potential savings can easily reach over five percent in fuel costs alone. Without the concern for fouling, a ship’s underwater coating can be engineered for corrosion protection and longevity rather than its need to eliminate the potential for biofouling. If realized on all the ships operating in the world today the energy savings would greatly reduce the presence of greenhouse gases, as well.

To eliminate the requirement for toxic paint and its cleaning waste, there needed to be a method to “groom” the biofilm from the underwater portion of a ship. The idea was to create important changes for the ships being built as well as for the environment. That is where the HullBUG (Hull Bioinspired Underwater Grooming) concept originated. “The most important feature of the HullBUG is its small size,” according to SeaRobotics Research Engineer, Dr. Kenneth Holappa. “It is only about half a meter in length. This was a necessary design feature, needed to allow the vehicle to maneuver over the curved surface of the hull while continually maintaining close contact with the surface.

system that helps it keep on course while cleaning a hull.

Because there are hazards associated with operating such a device underwater and in a harbor environment occasionally a HullBUG might be lost or destroyed during operation. Keeping the size and cost of the system low definitely helped to eliminate damage as a major obstacle to implementation. So, from the very beginning of the project, small size and low cost have been identified as being critical to the satisfactory implementation of the HullBUG project. As can be expected, this need to maintain a particular size and weight filtered into the selection of every component of the design.

Motion Control Components

The selection of the motors to drive the HullBUG involved a number of critical engineering constraints and compromises. SeaRobotics decided to make two basic models, one with wheels and one with tracks, and offer several options for keeping track of the system’s progress, which will be discussed later. Sizing of the motors, for example, required a calculated estimate of the power, speed, and torque characteristics of the manufactured devices. Determining factors included the resistance caused from pushing the grooming tool across the surface of the ship, the hydrodynamic resistance of the vehicle itself as it moved through the water, friction losses in the shaft seals that were used to protect the motors from the saltwater, and track or wheel friction dependent on which version of the unit was used.

interface boards about to be safely mounted inside the machine.

maxon motors offers a full line of fractional horsepower moving coil DC motors and brushless motors ranging in size from 6mm to 90mm, and from 30 mW to 500 watts. They also offer gearheads, controllers, and accessories. “The breadth of their product line and quality of their service helped us to feel comfortable that we had selected the right partner,” Ken said. Flat motors manufactured by maxon Precision Motor provide long life along with their low profile package. The entire EC series of brushless motors are electronically commutated, which enables them to have extremely long motor life since there are no mechanical brushes to wear out. The motors incorporate ball bearings or ruby bearings that also add to the longevity of the motors, especially needed in such harsh conditions. The flat motors were designed specifically for robotics applications where size and weight are important selection criteria. The EC45 flat motors selected for the HullBUG are very efficient and weigh only 75 grams. Continuous output power is 30 watts, while the maximum speed is 10,000 rpm (much faster than what was needed for this application). The important specification for this application was torque. Even under the potentially harsh environments that the HullBUG would be engaged in, the EC45 offered a maximum continuous torque up to 56.2 mNm depending on the winding chosen by the user. The Maxon brushless motors are built to IP54 standards, which was important to the application. Furthermore, the motors were also available in the system voltage that SeaRobotics required for the HullBUG application.

According to Ken, “The large load capacity of the shafts of the GP42 gearhead allowed the wheels to directly mount to the gearhead shaft, greatly reducing the complexity of the overall design of the system.” Gearheads manufactured by maxon are available in a wide range of ratios to enhance speed reduction and/or torque multiplication dependent on the needs of the user’s application. Concentric input and output helped to facilitate simpler and more direct mounting arrangements, as well.

Given that the HullBUG vehicle was to be completely autonomous, it had to be designed in such a way as to operate for many hours on batteries (cables would simply get in the way of the grooming operation). In order to maximize battery life, the grooming of the biofilm had to be performed in the most efficient manner possible. Navigating in a random pattern may eventually get the job done, for instance, but not in a reasonable amount of time. Plus, a typical ship presents a very large underwater surface, often as upwards of three thousand square meters. To keep this amount of area groomed it is expected that a user would employ multiple HullBUG vehicles to operate at the same time and, consequently, require a method of acquiring sophisticated coordinated navigation.

Navigating the HallBUG

A toolset of navigation modes has been created to allow multiple HullBUGs to efficiently groom a ship by dividing the ship’s underwater surface into regions. Numerous algorithms have been incorporated to accurately groom the ship in steps down to the turn of the bilge. Additional algorithms and associated sensors are used to allow efficient grooming of the flat bottom of the ship. Miniature acoustic ranging sonar (MARS) is also an option for navigation control of the HullBUG. This is where a very small close range, pencil beam sonar was specifically developed to allow the vehicle to “see” an upcoming wall or cliff condition such as bilge keels and bow thrusters. Yet another mode of navigation uses a MEMS rate sensor for navigation information. Another feedback mode uses encoder based odometry. Hall sensor feedback from the motor is used as an encoder signal to establish an accurate estimate of odometry. Hall sensors were used instead of optical encoders because of size and cost. The Hall sensors provide better than 1mm accuracy in the measurement of odometry with the motor/gearhead combination chosen.

Ongoing Software Development

An autonomous vehicle is often software heavy in terms of engineering efforts once you’ve selected and implemented the proper motion control system. Getting smooth reliable navigation maneuvers that result in accurate positioning in a widely varying environment was one of the more difficult challenges for the design team. Multiple layers of software were necessary for handling the number and variety of possible events that can occur during grooming. And, the proper organization of the control logic to allow extensibility of navigation behavior was the most difficult part of this complex system. “Software development will continue to be an ongoing effort even after the years already put into it,” Ken said. “Though the vehicle is completely operational, there remains a considerable amount of on-ship testing to be done.” As the project moves forward and into the field, there will no doubt be additional issues that will crop up and need to be addressed, as well. Even now, the vehicle must be able to reliably accomplish its task in a hostile environment and in an unmapped terrain. Then it has to be able to return to the waterline of the ship for retrieval.

This operation must be done repeatedly for days, months, and years, and with multiple systems in the water at the same time. Although this sounds as though it is overly difficult, according to Ken, “A technician was recently trained to use the vehicle and was fully competent within a short period of time. The user interface was borrowed from SeaRobotics’ Unmanned Surface Vehicle (USV) product line and presented an intuitive graphics-driven interface that has hundreds of hours of use by many different customers.” The vehicle is operational and the navigation software is working. The next primary focus will be the structuring of the interface to improve ease of use and allow non-engineering personnel to manage operations.

The Engineering Edge – Application – Trunnion Grinding Slide for Oil Field

 

We are shipping another slide today for the oil patch. When Weir Oil and Gas called with a slide application that required special engineering, LM76 was all ears – as it was right up our alley. This slide is a Trunnion Grinding Slide which has a 56HP motor running at 3500 RPM mounted to the Y Axis – with a 12″ grinding wheel attached. The X Axis (52″ Stroke) runs on 440C stainless linear ball bearings that have special beryllium copper scraper seal cartridges while the Y Axis (4″ Stroke) employs profile rail guides with double scraper seal kits. Our customer did not want protective bellows so we had to ensure grinding debris would not cause bearing or screw/nut failures. On both axis, we employed our proprietary “Polymatrix, Double Preloaded Nuts” as opposed to recirculating ball nuts. Why LM76? Good question…we were the only company that got back to them with a thoughtful solution.

Motion Control Application- Maxon Is A Part of NASA’s InSight Mission!

Swiss motor ventures deep under the surface of Mars.

 

Maxon Logo

 

Fall River, MA — Motion Control Components Application – The InSight probe landed on Mars to shed new light on the formation of rocky planets. The mission entails driving a measuring probe five meters deep into the Martian ground. maxon engineers pulled out all the stops to make their motor fit for the job.

Tension was mounting among fans of space exploration, as the robotic InSight probe landed on Mars on November 26. If all goes according to plan, the stationary lander will proceed to carry out various measurements over a period of two years and provide important insights into Mars and the formation of Earth. The mission is being conducted by the Jet Propulsion Laboratory (JPL) for NASA.

 

Motor rams penetrometer 5 meters deep into the ground

DC motors from the Obwalden-based drive specialist maxon motor are also on board. A compact motor-gearhead combination with a diameter of 22 millimeters is used in the HP3 probe developed by the German Aerospace Center (DLR). It is designed to determine the temperature profile of the planet. Specifically, the maxon drive is located in a rod-shaped penetrometer, nicknamed “the Mole” by the developers. This penetrometer is autonomously driven five meters into the ground. To achieve this, the motor tensions a spring with each revolution. The spring then releases with great force, executing a powerful downward punch. In this way, the “Mole” gradually burrows downwards – over a period of several weeks, pulling along a cable that is equipped with sensors to help the researchers determine the thermal state of the interior of Mars and draw conclusions about its origin. Since Mars is a rocky planet like Earth, the scientific results may also help gain a better understanding of our own planet.

Mars is not a very friendly environment for technology. Nonetheless, more than a hundred maxon drives have already proven their worth on the Red Planet. The current InSight mission, however, posed additional challenges for the Swiss engineers. To efficiently drive the penetrometer into the ground, the DC motor needs to withstand forces in excess of 400 g – and more than 100,000 times. It took a number of variations and failed tests to find the right solution. The result is a standard DCX 22 motor, greatly modified with additional welding rings, bearing welds and specially shortened brushes. The utilized GP 22 HD gearhead, on the other hand, only needed Mars-specific lubrication.

Say hello to an old acquaintance

The InSight probe is powered by two solar panels for the duration of its mission. To save costs, JPL repurposed designs from the successful Phoenix mission, using a maxon DC motor developed some time ago to extend the solar panels. This type of motor, an RE 25, has ensured that NASA’s Opportunity rover has been active on Mars for more than 14 years (even if it is currently in deep sleep due to a sandstorm). Thus, two generations of maxon drives come together in the InSight robot probe to jointly contribute to the mission’s success.

Maxon Logo

Fall River, MA — Motion Control Components Application – A maxon A-max 12 with precious metal brushes is installed in the central shutter of the S lens. The maxon A max program stands for high-quality DC motors with an optimal price/performance ratio.

With its Leica S system, camera manufacturer Leica offers a unique combination of performance features for digital photography. It combines the image quality of a medium-format camera with the handling, speed and flexibility of a small-format camera. The lenses used in the Leica S system have a built-in dedicated processor for controlling the auto focus. The lenses are also available with a central shutter for maximum flexibility when using a flash. Besides the focal-plane shutter, which is integrated in the camera, the central shutter is one of two common designs. The central shutter is typically located at a “central” position in the lens assembly, between the optical lens elements. It consists of several blades arranged around the optical axis in a concentric pattern. When the shutter release of the camera is pressed, the blades snap back from this axis synchronously and let the light fall on the sensor.

With SLR cameras, the central shutter first closes after the shutter release, because all the settings were made with an open shutter. The mirror swings up, then the central shutter opens for the duration of the exposure before closing again. Finally, the mirror swings back into the path of light, and the shutter opens. Even though it employs the classic solution of mechanical springs for the efficient storage of potential energy, the central shutter is a piece of cutting-edge technology. The tensioned-spring principle contributes significantly to the extremely compact dimensions.

Small motor for high tension

The springs are tensioned by a specially developed maxon motor with a high-precision overrunning clutch and release their stored energy to activate the shutter blades when the shutter release is depressed. A specially constructed solution prevents the blades from rebounding when the shutter is opened or closed. A microprocessor-controlled pawl and ratchet mechanism controls the shutter cycle via two electromagnetically activated plungers.

The gear motor of maxon motor is used for tensioning three springs that store the energy for the central shutter. A maxon A-max 12 motor is used as the base motor. The gearhead is an all-new development and is adapted to the available space. This presented a special challenge to the gear motor in the central shutter of the Leica lens. What was needed and developed was a very compact, enclosed and sealed custom version of the gearhead with perpendicular power transmission to toothed gear of the central shutter through a crown gear, for a life span of more than 100.000 releases.

Motion Control Application – Intelligent robot systems are increasingly being used in disaster control, rescue missions and salvage operations!

After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant. There it measured the radioactivity levels and sent HD images to the world outside.

Wherever it is too dangerous for humans. Robots that can look for survivors after an explosion, an earthquake or other natural disasters, providing humans with a view of inaccessible areas. Powerful EC motors from maxon motor give the Japanese rescue robot “Quince” its drive.motion control application robot Quince

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Robots that are used in disaster areas have to have a very high level of adaptability. They have to be fairly small, not too heavy and maneuverable enough to get through cracks or narrow spaces to reach areas deep inside a building. Furthermore rough terrain should present no problem. These rescue robots enter and explore buildings to determine if there are gases, radiation or other life-threatening hazards, before human rescue teams can search the area. Quince has proven that it fulfills all these demands. After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant in June 2011. There it measured the radioactivity levels and sent HD images to the world outside (To see video – CLICK HERE). The robot was able to supply valuable information from areas where no human can set foot.motion control robot goes down stairs

Quince weighs 27 kg and is equipped with four moving caterpillar drives (flippers). These flippers automatically adapt their angular position to the surface underneath – regardless of whether the robot is climbing steep stairs or crossing rough terrain. Correct ground contact is a very important prerequisite. This contact is accurately analyzed by measuring the power consumption of the flipper motors. Furthermore PSD (Position-Sensitive Device) sensors on the front and rear flippers measure the distance to the ground. In addition to a gripper arm (see fig. 2), two laser scanners can also be attached to the robot. These scanners are capable of accurately capturing the structure of the terrain.motion control robot navigates rough terrain

Additionally Quince is equipped with a “bird’s eye camera” and can travel quite fast, at 1.6 meters per second. The operator that controls the robot has to tell it which direction to take, but the robot itself determines the optimal flipper positions for crossing various surfaces, for example stairs. Newer Quince motors have additionally been equipped with a device for collecting radio-active dust or ultra-fine particles, as well as a 3D scanner. To ensure that no robot is lost, a connection to a wireless network is possible, which is the only way to navigate the robot if the connection cable breaks.

The rescue robot was developed by Eiji Koyanagi, Vice-Director of the Chiba Institute of Technology Future Robotics Technology Center (fuRO). Koyanagi started his career as a teacher – at the age of 51, he became a professor. This means that he has a completely different background than other researchers in the field of robotics. Quince has been specially designed for extreme conditions in environments where it would be too dangerous for humans. Therefore its main area of application is disaster areas. “When you develop a robot, you first have to consider the tasks that it will perform later. That is the biggest challenge,” explains Koyanagi. Hitherto eight Quince robots have been built. But before this could be done, all components had to be 100% functional. To this end, various trials were run in the large “Disaster City” training area in College Station, Texas. Quince was the only robot that successfully completed the entire obstacle course at the site as part of a RoboCup contest. In preparation for using the robot inside the Fukushima Daiichi nuclear power plant, several specific customizations were required. “The conditions in the nuclear reactor buildings are very tough. If we had attempted to send Quince in without modifications, it would probably have met its end,” says Koyanagi. Therefore the robot had to be able to survive a fall from approx. 2 m high unscathed, and had to be largely maintenance-free.

Powerful motors to beat every obstacle

Motion Control -Maxon Motors used in robot Quince

Where the motor selection was concerned, fuRO required absolutely reliable drives. The motors have to provide high power and high efficiency, yet be small and light. These requirements were precisely met by maxon motors, explains Koyanagi. Six powerful maxon motors drive the robot. The brushless EC-4pole 30 direct current motors each provide 200 W; two of these have been installed in the two main chains. The powerful 4-pole units give their all when Quince maneuvers its way across uneven terrain. Four additional motors (EC22) drive the moving chain drives (flippers). These can automatically adapt their angular position to the surface below. The 3D scanner unit of Quince is moved to the right position by an RE-max 24. Thanks to the special winding technology and the 4-pole magnets, the maxon EC-4pole drives are unbeatable when it comes to delivering the highest driving power per unit of volume and weight. The motors have no cogging torque, high efficiency, and excellent control dynamics. The metal housing additionally ensures good heat dissipation and mechanical stability. All motors of the chain drives have been combined with the GP32HP (High Power) planetary gearhead with MR encoder. This gearhead was customized by installing a large ball bearing and a reinforced motor shaft. With this power pack, Quince has no trouble managing almost any obstacle.

Motion Control Application- Intra-aortic pump powered by miniature brushless DC motors provides heart failure patients an aid to help hearts rest and heal!

The Maxon EC 6 motor brushless DC motor is the second smallest drive in the maxon family.

Maxon motion control application - Inter-aortic heart Pump

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Chronic heart failure patients draw hope from a new technology. A team of life science entrepreneurs in Houston, Texas has developed the first catheter-deployed circulatory assist device intended for long-term use. Procyrion, Inc.’s Aortix™ provides a minimally invasive treatment option for the more than two million chronic heart failure patients in the USA alone who are too sick for medication. This pre-clinical cardiologist tool dramatically reduces risks associated with circulatory support devices and enables treatment of younger, healthier patients before progressive damage occurs

Assisting the natural function of the heart, the intra-aortic pump has been thoughtfully designed as an alternative to large, cumbersome surgical devices currently providing full circulatory support. Unlike these devices, Aortix provides minimal procedural risk. Measuring approximately 6 mm in diameter and 6.5 cm long, a cardiologist can deliver Aortix via a catheter in the femoral artery to the descending thoracic aorta. Once the catheter sheath is retracted, the self-expanding nickel-titanium anchors deploy to affix the pump to the aortic wall.

Aortix accelerates a portion of the body’s native blood flow within the pump and pushes it through fluid entrainment ports directed downstream. The jets entrain native aortic flow, transferring energy to the cardiovascular system and increasing blood flow to vital organs such as the kidneys. Additionally, in a model of chronic heart failure, Aortix decreased energy consumption of the heart by 39 percent, allowing the heart to operate more efficiently, encouraging cardiac rehabilitation and recovery.

Maxon motion control application - Inter-aortic heart Pump

Procyrion has been working with maxon for almost two years to develop a motor for this unique and demanding application. The basis for the Aortix device is a maxon EC6 motor with some customization including the electrical lead, shaft length, and bearing assemblies – all designed to make the pump durable and biocompatible. maxon also designed a high efficiency motor core for this application, which extends battery life and produces less heat so it doesn’t adversely affect the circulating blood. In addition, maxon is working closely with Procyrion to implement a magnetic torque drive, so the motor could be mounted inside a hermetically sealed chamber. This configuration eliminates the possibility of blood entering the motor core. The magnetically coupled pump arrangement is a method sometimes used for giant pumps in the oil field, but because of maxon’s breadth of experience across multiple industries, the company was able to help the Procyrion team successfully transfer this technology to a miniature scale medical application.

Each Aortix device consists of a small, continuous flow pump mounted within a self-expanding anchoring system. The anchored pump attaches to a flexible power lead, which can be tunneled to a desired transdermal exit site or to a Transcutaneous Energy Transfer (TET) system for subcutaneous implantation without an indwelling power lead.

Maxon motion control application - Inter-aortic heart Pump

Presently, the device can operate for over eight hours on a single battery pack. The external battery pack and control unit have been designed to be “hot swappable”, meaning the battery can be changed without needing to stop the device. A variety of charging devices can be used.

“Aortix reduces the heart’s energy consumption by 39 percent.”

The Procyrion team has also built a TET charging system that enables the battery to be charged wirelessly. This design has the potential to significantly reduce the risk of infection, common with other implantable heart pumps.

Maxon motion control application - Inter-aortic heart Pump

Because traditional assist devices replace heart function rather than support it, device failure can be fatal. With Aortix, a partial support device which doesn’t obstruct native blood flow, failure is not life threatening. Should the pump fail, the device can easily be retrieved and replaced in another minimally invasive, catheter-based procedure.

Motion Control Application – Universal XYZ Robot for Microscopy and Pipetting from Intellidrives!

Motion Control Component - Pipetting Robot

 

 

Motion Control Components - Intellidrives-Logo

 

Philadelphia, PA, – Motion Control Components and Systems – Manual pipetting is a time-consuming process that can lead to repetitive stress injuries. Automatic pipetting involves the use of robots to perform this type of tedious bench work, allowing scientists more time to design experiments and analyze data.

Overview

“Pipetting” refers to the use of pipettes, which are laboratory tools commonly used in biology and chemistry. They’re generally used to dispense a measured volume of liquid, although a pipette’s specific design can vary considerably from single pieces made of glass to complex devices that use electronics. Many types of pipettes draw up the liquid by creating a partial vacuum above the chamber that holds the liquid. A pipette’s accuracy and precision primarily depends on its design.

Intellidrives Motion Control Component - Pipetting Robot

Automatic Pipetting

Manual pipetting is often complex and inefficient, leading to increased preparation time, training requirements and operational costs. This process also increases the chances of procedural errors in an experiment.

An automated pipetting system generally transfers liquids between pre-selected containers in a programmed sequence. They’re also known as liquid-handling robots, especially when they include other components such as laboratory shakers and microplate washers in addition to pipettes. The ability to increase throughput and reproducibility is one of the primary advantages of liquid-handling robots.

These robots dispense liquids into containers such as tubes and wells. They’re often integrated into other systems such as liquid chromatographic systems, typically as automated injection modules. In addition to saving valuable time for scientists, liquid-handling robots are especially useful for preparing samples more precisely in applications requiring high-throughput in complex sequences. They may also be used for weighing samples in liquid and powder form as well as performing many types of biological and chemical assays.

These systems may contain additional components for feeding samples into heating and cooling systems, typically for the purpose of thermal cycling. Their physical construction may also allow them to easily integrate into peripheral lab-ware. For example, a liquid handler can be fitted with robotic arms that the user can program to manipulate external lab-ware, further enhancing the robot’s uses. Other features of automated liquid-handling robots include start/stop functions and the ability to coordinate the steps in a sequence, which is especially useful when performing assays.

Pipetting Robots Confirgurations

XYZ robots are automated liquid-handling platforms that provide a range of solutions for preparing samples. They provide a common platform that allows scientists to easily share protocols and reproduce results. These robots automate experiments that scientists would otherwise need to perform manually, allowing them more time to answer important questions.

IntelLiDrives XYZ robots support interfaces to external I/O devices such as fluid pumps. An adaptor is also available for the XYZ robot that allows it to hold a Society for Biomolecular Screening (SBS)-standard multi-well plate. This system allows the user to perform pipetting applications such as automated microscopy with a high degree of resolution and repeatability.

The user can also change the placement and orientation of individual devices to provide a variety of configurations, and one stage can even be removed entirely to create an XY setup.

Robot Programming

Users programs pipetting sequences, using GUI (graphical user interface) with icon-based programming or writing sequence scripts with a VB-like language. No programming experience required to create complex pipetting sequences with interfaces to external pumps and other labware hardware.

Intellidrives Motion Control Component - Pipetting Robot Controls

USB interface and ability to receive/execute in real time commands over the USB port, allows robot to be integrated into complex laboratory automation systems.

Application – Rotary Table from Intellidrives Tackles Big Wafers!

INTELLIDRIVES’s Direct drive rotary servo tables.

Intellidrives Motion Control Component - Rotary Table for Big Wafers

Motion Control Components - Intellidrives-Logo

 

Philadelphia, PA, — Motion Control Components and Systems – The ACR-335UT direct drive rotary table from IntelLiDrives adapts linear motor technology, coupled with precision bearings, to provide faster and more accurate handling of the 300 mm semiconductor wafers.

The 335 mm diameter center opening in the ACR-335UT rotary table easily accommodates large 300 mm (12 inch) semiconductor wafers, allowing for extraction of the chip dies from the wafer during semiconductor assembly manufacturing processes or dual side wafer inspection.

Presently, semiconductor assembly equipment manufacturers do only limited wafer rotation, but ACR-335UT stage goes 360°, at up to 300 rpm speed.

Intellidrives Motion Control Component - Rotary Table for Big Wafers Actuator

This large angle wafer rotation can be done without need to align wafer carrier before placement on the table, thereby increasing throughput. An XY table that carries the rotary table is used for linear Cartesian Alignment. The large open center allows equipment above and below the table to extract precut integrated circuit dies cut from the 300 mm wafer or to do dual side wafer measurement and inspection.

 

Intellidrives Motion Control Component - Rotary Table for Big Wafers in XY Frame

Today’s mechanical drive technologies used in processing 200 mm (8 inch wafers) such as gear drive, worm drive and belt all lack positioning stiffness and accuracy. While worm gear rotary tables can fully rotate wafer , it speed is in single digit rpm. Belt drives can rotate at high speeds, but low belt stiffness and high drive inertia results is low accuracy and poor dynamics.

While these characteristics could be tolerated in the past, since it was not until advent of the large semiconductor wafers that a high accurate, precise and large open aperture rotary actuator was needed.

The ACR-335UT rotary table is essentially a linear motor “curved” to form a ring. There are 16 RotoLinear motoring modules (up 24 modules can be installed for higher torque capability) within the ring that forms the motor. Axial placement of these modules along with the ultra-thin bearing system allowed design of the very low profile rotary stage.

The positioning stiffness of the direct drive ACR-350UT rotary table allows it to achieve and to maintain arc-sec accuracy at hundreds of rpm and excellent dynamics even during fast Cartesian (XY) wafer indexing.

Also vital, and the major manufacturing challenges, were the tight tolerances on the axial and radial bearings that allowed to achieve both axial and radial run-outs well under 10 microns.

AccuRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the AccuRing stage yields the lowest total cost of ownership.

Compact package and Superior design of the AccuRing rotary stages was optimized to minimize stage height. The low profile of the stage reduces total system working height. Angular contact bearings are used to maximize performance with respect to wobble, moment stiffness and friction. AccuRing stage has large clear center aperture that can be used for air or wire line feed-through or beam delivery.

AccuRing utilizes direct drive three phase planar brushless motor technology. There are no brushes to replace and no gear trains or belts to maintain. Coreless magnetic design assures smooth rotation and dynamic performance.

Accurate Positioning is assured with contact-less encoder. The motor and rotary encoders are directly coupled to eliminate coupling backlash. The low inertia and zero backlash make AccuRing the ideal solution for applications requiring frequent directional changes.

Motion Control Application- Maxon Drives Help People Walk Again!

At the first Cybathlon in Zürich, researchers are presenting the world’s best exoskeletons – devices that enable paraplegics to walk again. Motors from Switzerland play a central part in this development.

Maxon motion control application - Helping People Walk Again

Maxon Logo

Fall River, MA — Motion Control Components Application – On October 8th 2016, people with paraplegia are going on a footrace at the Cybathlon in Zürich. Aided by exoskeletons, they will compete against each other on an obstacle course to show the public how far advanced technology has come in this area.

Switzerland, is playing a central role in this process. Many of the exoskeletons are fitted with components from the canton of Obwalden – components without which there wouldn’t be a lot of movement to be observed.

From the planet Mars to an exoskeleton

Robotic suits have to be both powerful and lightweight. Too much weight would cause the battery to drain in no time. This presents a big challenge to developers. Most of the motors that are strong enough to power an exoskeleton are large and heavy. This is why engineers are turning to the Swiss company that already developed the drives for NASA’s Mars rovers: maxon motor. maxon drives are powerful, lightweight, and energy-efficient, meaning that they can conserve battery power, and be very durable.

“We spent decades perfecting our motors”, says maxon CEO Eugen Elmiger. A lot of money has gone into research and development. It was worth it: These days, the motors from Switzerland can be found everywhere, in robots, airplanes, cars, and medical devices.

Knowledge yields an advantage in the market

Providing competent technical support for customers is just as important as delivering high-quality products. Small businesses and start-ups often approach maxon with specific drive technology problems that they lack the expert knowledge to solve by themselves. maxon motor, in turn is able to help with its extensive experience in the field, a strength that lets the company stand out from the international competition. “Our knowledge and the ability to give expert advice are a great advantage in the market,” says Elmiger. The Cybathlon is a good example: In the field of exoskeletons, the Swiss company has a pretty clear idea about what’s important besides choosing the right motor. As a result, quite a few of the participating teams are using products from Switzerland. The same is true for other disciplines, such as prosthetic arms or legs and electrical wheelchairs.

For examples, read maxon’s exclusive Cybathlon brochure or visit the new site for technology enthusiasts – drive.tech

maxon supports the Cybathlon as a sponsor and partner

The Cybathlon games are organized by the ETH Zürich and are being held for the first time on October 8, 2016 at the Swiss Arena in Zürich. Around 80 teams from all over the world will be participating. The machine-assisted competitors will compete against one another in six disciplines: prosthetic legs, prosthetic arms, exoskeletons, motorized wheelchairs, bicycles with muscle stimulation, and virtual racing using thought control. What’s not allowed at the Paralympics is an absolute must at the Cybathlon: the use of state-of-the-art technology. “Our aim with the Cybathlon is to break down barriers between the general public, people with disabilities, and scientists,” says ETH professor Robert Riener, who invented the Cybathlon.

The Swiss drive specialist maxon motor supports the Cybathlon as a sponsor and partner. The company will be present at the games with a workshop for the teams and a small exhibition about the history of prosthetics.

Motion Control Application – Wearable Pumps for Medical Devices Count on Ball Screws from Steinmeyer!

Motion Control Application - Steinmeyer Ball Screws used in Medical Pumps

Steinmeyer Logo

 

BURLINGTON, MA –Motion Control Applications – Motion Control Components – There has been a tremendous amount of innovation lately in the design of medical devices and lab instruments. One of the critical aspects of the new products being developed is linear motion. And Steinmeyer is proud to be directly involved in providing drive solutions to our cutting-edge customers. We currently have several on-going applications involving wearable pumps driven by ball screws, and I wanted to share some of the specifics.

Implantable medical devices naturally place extreme requirements on size, materials, lifetime, and reliability. These constraints drive up cost and complexity. Incorporating all of this function into a single implantable is extremely challenging. Not only that, but servicing the pump requires major surgery!

One solution is to break down the system into two components—one implantable and one wearable. The implantable component handles minimal functionality and consists simply of a balloon. The wearable component enjoys much looser design requirements. In the projects we are working with, a wearable pump is used to drive compressed air through a catheter that passes into the body.

A wearable pump offers the advantages of being small, quiet, and very reliable. That is where precision ball screws come into play. Steinmeyer offers standard miniature screws in diameters 3 to 16 mm. The diameter typically required for this application ranges from 8 to 12 mm. Custom products can be developed as well for applications that need it. Steinmeyer ball screws also feature our proprietary super finishing process, called optiSLITE. This improves the surface quality of the shaft threads for reduced friction torque, quieter operation, and longer life.

About Steinmeyer

Steinmeyer is the world’s longest continuously-operating manufacturer of commercial ball screws. In the realm of linear motion control, our company has become synonymous with precision, innovation, and exacting standards of quality.

Steinmeyer’s extensive product line is used widely in drive systems for industrial machines as well as precision positioning in optical instruments, medical devices, and other mechatronic applications. www.steinmeyer.com

Motion Control Application Story – Sound of Light from Intellidrives!

Optoacoustic tomography (OAT) is a technique for generating high-resolution images of biological tissue that scatters light waves, typically biological tissue..

Picture

Philadelphia, PA, — Motion Control Components and Systems – Application – OAT systems create these images with pulses of dark red light that have a maximum duration of 50 nanoseconds. These pulses heat the tissue and cause it to expand launching ultrasound wave, a phenomenon known scientifically as an optoacoustic effect. This thermo-elastic expansion produces high-frequency acoustic or ultrasonic waves that the imaging scanner detects and uses to create an image with computational methods such as filtered back-projection. OAT is unaffected by the scattering of photons, allowing it to take high-resolution images of deep biological tissue.

OAT also uses techniques such as functional and molecular imaging to identify each absorbing molecule that contributed to the image brightness. OAT uses light of different wavelengths to target various molecules of medical interest, such as hemoglobin, oxyhemoglobin and melanin.

This approach allows OAT to distinguish between molecules in the target tissue with different light absorbing properties, including exogenous contrast agents such as imaging probes to appear distinctly different on optoacoustic images.

Science at Work

Scientists at Tomowave Laboratories use technologies based on light and sound to make imaging systems for the healthcare industry. These technologies use optoacoustic and laser ultrasonic methods to produce modalities such as laser optoacoustic ultrasonic imaging system, which uses pulses of laser light with a dark red color.

Biological tissue absorbs this light, causing it to heat-up by a fraction of one degree. The resulting temperature increase causes an increase in pressure, which generates ultrasonic (optoacoustic) waves. The imaging scanner uses arrays of transducers to measure these ultrasound waves at different locations to generate images of internal tissue of different human and animal organs, such as breast or prostate. These systems listen to the sound of light, allowing doctors to detect and diagnose cancer and other conditions.

Recently, engineers at Tomowave have developed a system that combines light and sound to generate three-dimensional images of tissue submerged in the imaging module, primarily the tissue of small animals used for research purposes and development of new contrast agents or therapeutic methods.

This optoacoustic tomography system is the first of its kind to produce functional 3D images of biological tissue with equally high resolution in each volumetric direction. The system provides comprehensive information on anatomy and function. These images are especially useful for studying the distribution of blood and its oxygenation level.

Preclinical research systems rotate the object of study, while the module itself rotates in systems used in clinical settings such as breast imaging systems.

Noninvasive breast imaging systems apply the same technology to produce three-dimensional volumetric optoacoustic images and stack of two-dimensional ultrasonic images, allowing for image co-registration.

These systems produce scans at different wavelengths in minutes with minimal patient discomfort.

Custom software processes the volumetric data according to the specific items of interest, which may include hemoglobin content, oxygen saturation and vasculature visualization.

The imaging system uses a PSR180UT low profile rotary servo table from IntelLiDrives to rotate the imaging module at a constant speed, which is programmed in advance.

A real time precision encoder output allows synchronization of the image capture with the motor’s position, allowing the system to reconstruct the images in three dimensions.
