Motion Control – Maxon drives are heading to the Red Planet with NASA’s Perseverance Rover!

Motion Control – Application – Maxon drives heading to the Red Planet!

In July, NASA will be sending its fifth rover to Mars. Its main mission is to collect soil samples that will be analyzed on Earth at a later time. The rover will also carry a helicopter that will perform the first flights on the Red Planet. maxon’s precision DC and BLDC motors will be used for numerous mission-critical tasks.

motion control - maxon motorTaunton, MA — Motion Control Products & Application – maxon drive systems are very familiar with Mars. Our drives have been used in virtually every successful robotic mission over the last three decades. There are now more than 100 of them on the Red Planet and there are likely to be more soon. The launch window for NASA’s next mission opens on July 22nd. An Atlas V rocket will launch the new Perseverance rover on its way to Mars, where it will be searching for signs of previous life on the planet. Its most important job is to take multiple soil samples, seal them in containers and deposit them on the surface of Mars so that a future mission can return them to Earth. Several maxon motors will be used to handle the samples inside the rover. For example, maxon DC motors are installed in the robotic arm, which moves the samples from station to station. Maxon motors will also be used for sealing and depositing the sample containers.

NASA’s Jet Propulsion Laboratory (JPL), is carrying out the mission, and have asked maxon to produce 10 drives for the rover. As with almost all previous Mars missions, these drives are based on standard products from maxon’s catalog with modifications. For the first time, NASA is using brushless DC motors, including: nine EC 32 flat and one EC 20 flat in combination with a GP 22 UP planetary gearhead. Working closely with JPL specialists, maxon engineers developed the drives over several years and tested them thoroughly to achieve the highest standards of quality. “We’ve learned a lot from this exciting project,” says Robin Phillips, head of the maxon SpaceLab. “We now have very broad expertise in space applications and have established quality assurance processes that meet the expectations of the industry. Customers from other industries such as the medical sector, where requirements are often similar, can also benefit from this know-how.”  Space missions place the highest demands on drive systems. This includes vibrations during the rocket launch, vacuum during the journey, impacts on landing, and the harsh conditions on the surface of Mars, where temperatures fluctuate between -125 and +20 degrees Celsius and dust penetrates everywhere

Maxon DC motors control the Mars helicopter.

motion control - maxon mars motor

The Perseverance rover is expected to land on Mars on February 18, 2021 – but it won’t be alone. A drone helicopter called Ingenuity will be attached to the underside of the rover. It weighs 1.8 kilograms, is solar powered and will perform several short flights, as well as take aerial images. The main goal of this experiment is to test the concept for further drones of this kind. maxon has six brushed DCX motors with a diameter of 10 millimeters controlling the tilt of the rotor blades and the direction of flight. The drives are very light, dynamic and highly energy-efficient. These properties are crucial, because every gram counts on the Mars helicopter. Flying on Mars is not easy. The atmosphere is extremely thin, roughly comparable to the conditions on Earth at an altitude of 30 kilometers. The drone helicopter has flown in a simulated test environment in the JPL laboratory. Whether it will lift off on Mars remains to be seen. First, other obstacles, such as the rocket launch, must be successful. “We hope that everything goes well and that we’ll soon see our drives in action on Mars,” says maxon CEO Eugen Elmiger. “We’re all keeping our fingers crossed.”

Automation Motion Control – Application – Driver assist systems can help save lives by alerting driver of potential danger!

Automation Motion Control Products – Driver Assist System  

 Application – Driver assist systems can help save lives by alerting driver of potential danger!

 

automation motion control company - Maxon

automation motion control - brushed motors

Maxon A-max 16 brushed DC motor – This drive with a diameter of 16 millimeters (precious metal brushes, 2 Watt) was developed for use with an eccentric weight and a specified bearing.

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..

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.

underwater portion of ships. © 2011 SeaRobotics

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.

This close-up of the HullBUG clearly shows its sensor alignment
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.

In this close-up you can see the max-on EC45 brushless motor and
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.

Motion Control Application – Please smile with maxon motors!

Motion Control Application – Digital SLR cameras can deliver extremely sharp photos – regardless of whether the photographer is a professional or a hobbyist. Not only does the skill of the photographer, but also the technology inside the camera play a key role. maxon drive systems help to create lightning-fast images.

motion control - leica lens with motor

 

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- A wasp shows the way!

Maxon motion control application - Wasp Stinger

What do wasps have to do with brain surgery?  At first glance, not a whole lot. However, one species serves as the model for an innovative brain surgery needle that is being developed by a team of researchers from England.

Maxon motion control application - Brain

Fall River, MA — Motion Control Components Application – In tumor treatment, neurosurgeons today use a thin, rigid needle to inject medication into the affected brain tissue. This carries a relatively high risk of injuring healthy tissue, because a rigid needle only allows the surgeon to enter a certain region of the brain, following a straight path. The ideal solution would be a flexible operating tool.

This is where the London Imperial College comes in. In recent years, a team led by Prof. Rodriguez y Baena worked on developing a flexible robotic needle capable of reaching the deeper regions of the brain, while simultaneously avoiding especially sensitive areas. The young researchers sought to imitate the special mechanism employed by female wood wasps that use their thin but very strong drill-like stings to lay eggs inside the wood of trees.

Under the project name STING (Soft Tissue Intervention and Neurosurgical Guide), the scientists developed a prototype consisting of four segments with an overall diameter of 2.5 millimeters, held together by a puzzle-like interlocking mechanism. maxon drives provide the back-and-forth motion of the segments.

“The whole range”

Dr. Secoli is a member of the Mechatronics in Medicine Lab at the Imperial College. He selected the brushless maxon EC20 flat motor with a GP22 planetary gearhead for the application. An EPOS 24/2 positioning controller provides exact positioning. “Easy access to the API (Application Programming Interface) was the major key criterion of selection. On top of that, for fast-prototype system, maxon is the only manufacturer that offers the whole range of products: motor, gearhead, controller” says Dr. Secoli.

In early 2016, the team received a grant of 8.3 million euros from the European Union within the funding scheme Horizon2020. The new project codename EDEN2020 (Enhanced Delivery Ecosystem for Neurosurgery www.eden2020.eu), aims to set a new standard in the field of neurosurgical diagnostics and therapy by 2020.
