motion control - application


motion control - maxon motorsTaunton, MA — Motion Control Products – The Cipollini Flusso is a performance e-road bike that weighs only 10.7 kg. With a weight of less than 16 kg, the TRANSALPES E1 sets standards in the electrified trail and enduro segment. Both e-bikes put a natural feel at the center of the riding experience.

There is an emerging trend in the e-bike market towards lightweight systems that are almost indistinguishable from standard bicycles. This development is supported by smaller, more powerful motors and improved battery technologies. “Integration is the key word,” says Michele Tittonel, R&D Coordinator at Cipollini. “The second generation of e-race bikes will be powered by electric motors fully integrated into the bike design and complemented with high-end components.”

Cipollini set out to develop one of the lightest e-race bikes in the world without compromising reliability and duration of assistance. Now the Italian bike manufacturer is introducing the new Flusso, which weighs just 10.7 kg

The Cipollini Flusso is equipped with maxon’s BIKEDRIVE Air system, which weighs just 3.5 kilograms including the battery. At its heart is a mid-mounted motor that delivers 30 Nm of torque. Thanks to a special free-wheel technology it’s easy to pedal even without electric assistance. Michele Tittonel says, “The natural feeling of riding is absolutely crucial; after all, physical effort should remain part of the experience.”

Motion Control -What To Consider When Specifying A Linear Slide

Motion Control – Tutorial

Considerations when specifying a linear slide for a new or existing application.

By Mike Quinn • LM76

When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this:

Does an off-the-shelf linear slide (or a stock linear slide from a catalog) fully satisfy the application?

motion control - lm76

Off-the-shelf linear slides are advantageous for their quick delivery and lower cost than that of custom components. No wonder most linear-motion designs do in fact employ off-the-shelf linear slides from various component and system suppliers.

Motion Control – The Mars helicopter continues to makes history – with maxon’s precision motors!

Motion Control – Mars helicopter has maxon’s motors!

Space fans are thrilled: NASA’s Ingenuity helicopter has successfully completed its pioneering flight on Mars. This is the first time in the history of powered, unmanned spaceflight that a device has flown in a controlled manner on another planet.

motion control - mars helicopter


motion control - maxonTaunton, MA — Motion Control Products – A short flight for “Ingenuity,” but a big success for unmanned space flight. NASA’s Mars helicopter flew over the surface of the Red Planet for about 40 seconds on Monday, April 19th and landed back on four legs. From NASA’s perspective, this is a historic event similar to the Wright brothers’ first controlled flight in 1903.

With the Mars helicopter, the concept of powered, unmanned, and autonomous flights on foreign planets is being tested. This is comparable to the first Mars rover “Sojourner”, which paved the way for scientific follow-up missions such as “Curiosity” and currently “Perseverance”. “Ingenuity” is about to complete several flights over a period of 30 days, each lasting up to 90 seconds and reaching a maximum altitude of five meters.

Reaching New Levels of Speed, Lifetime, and Force Sensitivity

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

Situation:

In the area of automated laboratory equipment, servo-controlled pipetting modules are a key component of high-throughput systems. A major, global OEM had been using an off-the-shelf linear actuator to drive the pipette. This actuator had a limited range of capability in terms of speed, positioning accuracy, and force sensitivity. Although it met the minimum technical requirements and was cost-effective, engineers soon were asked to push performance to the next level.

 

Challenge:

The company decided to develop a next-generation system. Throughput was essential, as it wanted to target the largest hospitals and laboratories handling tens of thousands of samples annually. The pipetting module also needed to have enhanced flexibility to support a greater variety of operations. It should allow for a wider range of speeds and be highly accurate in both positioning and bottom-finding. Engineers were also tasked with achieving a 10-year lifetime with little or no maintenance. This high lifetime was critical because their business model included free field service. To meet these new requirements, the actuator would have to be redesigned. In particular, the bearing configuration did not support the required accuracy and sensitivity. The supplier was unwilling to modify its design. Company engineers realized that they would have to design a custom actuator.

Resolution:

They came to Steinmeyer for a precision ground ball screw. They knew that Steinmeyer had world-class quality and a very wide selection of miniature screw sizes. For this project, they were able to consider shaft diameters of 5mm or 6mm, with pitch down to 0.5mm! They selected a 6mm screw to meet the challenge. Company engineers conducted extensive performance testing on the first prototype quantities. They put the new module through an exhaustive regimen of motion, and measured positioning, force sensitivity, friction torque, motor current, and other parameters. They verified that their module design met all of the new performance requirements. The company has since achieved FDA approval for the new system and formally launched commercial sales.

Future Plans:

Noise minimization is important for laboratory equipment. The next generation pipetting module will look to ensure the quietest possible operation. The OEM will be evaluating our proprietary super-finishing process called optiSLITE. This technology removes the largest irregularities left over from thread grinding of the shaft. The resulting surface yields a noticeably smoother and quieter operation.

Linear Motion Application – How Do You Move Articles of Antiquity?

Very Carefully With A High Load Rail System from LM76!

motion control - linear guides

E. Longmeadow, MA – — The Boston Museum of Fine Arts (MFA) has to move articles of antiquity from one location to another. In this instance, they are moving a 5000 year old relief (hieroglyphics) weighing 8000 pounds to a new location in the Museum. Here is a frontal photo of the Relief from The Tomb of Senenuka.

Part of wall from tomb of Senenuka; nine stones fitting together and including two niches; lower left piece smooth limestone; upper far left preliminary black ink sketch; right of this sketch is a complete relief showing two seated figures; central piece has large scene of seated male on the left and other smaller male figure to the right; upper far right male figure relief outline; left of this again a scene of two seated figures at a table.

Senenuka Time of Khufu or Khafre (Maybe Dyn 5?) Overseer of the Pyramid-town of Khufu, Director of King’s wad-priests, Boundary official of a settlement, etc.

The MFA contracted CBI Consulting of Boston to design the frame and fixturing. Craig Barnes, an award winning architectural engineer called Mike Quinn of LM76 to review the linear motion application. Over the course of several weeks, LM76 and design partner Todd Kanipe designed a telescoping, high load roller/linear motion rail system that won approval. According to CBI’s Keith Bouchard, the linear rail system moves very smoothly and so far meets the expectations of this program.”

Linear Motion Application – According to MFA Antiquity Specialist Jean Louis Lachevere, “All of these moves present very real dangers to the artifact being transported. In this case, we have a 8000 pound relief which already has its problems due to age and the fact that it is limestone ( limestone is very vulnerable to the atmosphere ).” Seen from the front, the relief is straight. From the back, much of the top back is gone. Thus, the back of the relief has to be plastered so the back is flat. Pins are inserted to further reinforce the relief and then it is tipped on its back. It is then moved to its new atmospherically controlled display case. LM76’s design is used in the transfer from the dolly to the mounting rails and restraints in the display case. This 36” motion is fraught with things that can go wrong. One of the considerations is the possibility of an earthquake…any problem conceivable is taken into account.

Motion Control – Case Study – Ball Screws used in Wearable Pumps!

Motion Control – Case Study: Wearable Pumps!

motion control ball screw application

 


motion control productsThe 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.

motion control ball screw medical application

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.

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.

 


motion control - maxon motors© 2016 Preceyes
motion control component used in eye surgery

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.

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.

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.

Special solution for more than 400 g

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.

Fall River, MA — Motion Control Components Application – The Diamond Light Source particle accelerator in Oxfordshire has been used for projects as diverse as analyzing the effects of strain on aircraft wings, studying the behavior of the HIV virus, and even reading ancient letters without opening them. The 45,000m2 synchrotron facility works by accelerating electrons to 3GeV, generating beams of synchrotron light, up to ten billion times brighter than the sun, in order to understand molecular structures. To prevent electrons being lost in collision with air molecules, the whole process is undertaken in a vacuum; around one billion times lower than atmospheric pressure. Clearly, creating scientific instrumentation for such conditions requires great specialist knowledge, and Widnes-based Instrument Design Technology (IDT) supplies the world’s leading synchrotron facilities.

Motion Control Application Maxon Motor for Synchrotron

Diamond specified that the Double Crystal Monochromator for its new X-Ray Spectroscopy Beamline B18 should drive the crucial Bragg rotational axis with a DC motor rather than the usual stepper motor. IDT managing director Paul Murray explains: “The goal was to achieve higher rotation speeds, with a lower motor temperature and smoother drivetrain than the stepper motor we had used previously. Stepper motors are inherently noisy, and often sources of vibration. Eliminating this issue would immediately improve results from the DCM – but the new motor would have to work flawlessly in a vacuum of 10-8 Torr.” To help solve the problem IDT enlisted the help of Paul Williams, senior sales engineer at maxon motor UK. With experienced engineers handling the project at every stage, and a long history of customizing high-performance motors for applications as demanding as space and surgical robotics, maxon’s teams in Britain and Switzerland were eager to rise to the challenge of creating a cutomized solution. Williams says: “Because the vacuum in the synchrotron must not be compromised, each individual aspect of the motor and its construction had to be analyzed for possible outgassing. The challenge for us was effectively to create a brushless motor with virtually no glues or plastics, an incredibly high temperature tolerance, and excellent performance.”

The starting point for the custom motor was maxon’s EC22 Heavy Duty Motor. Although originally developed for sub-sea oil applications, the 22mm brushless motor’s laser-welded stainless steel construction and broad temperature range already addressed many of the needs of high vacuum applications – and being a brushless DC motor meant it would immediately be more efficient, quiet and responsive than the previous stepper motor.

Maxon Motor for Application in Synchrotron

When customizing the EC22 HD for use in the synchrotron, maxon accounted for a number of factors. First among these was temperature management. Motors in a vacuum cannot dissipate heat through convection in the normal way, so can be prone to overheating. It is therefore important to choose a motor with high temperature tolerance, stay well within its rated performance in air, and, if possible, position other components in such a way as to spread heat by conduction. A high ratio gearbox was also vital. High vacuums of 10-7 Torr and greater can pull gaseous compounds from materials such as plastics and glues, compromising performance and contaminating the vacuum – a problem known as outgassing.

Each component in the motor was individually tested, and upgraded as necessary. For example, standard PVC cable coating was replaced with a more inert, Kapton version. It was therefore important that the EC22 HD was already substantially made from stainless steel, rather than plastics. Because of the potential for outgassing, the usual glues and epoxies could not be used, and the motor was put together using extensive micro laser welding. From its work with space and aerospace projects, maxon knew how standard, light greases used on motor bearings are affected in low pressure conditions. It was therefore important to specify an extremely inert lubricant which was also thick enough to avoid giving off vapor under high vacuum – and to account for the effect of this change on the motor’s operating characteristics and anticipated life cycle. To finally remove any remaining outgassing threat, motors for controlled vacuum conditions are baked at 120ºC for 24 hours. Already purpose-built for temperatures in excess of 200º C, the EC22 HD proved an ideal starting point.

The Double Crystal Monochromator, incorporating the special maxon DC motor, is now in active service in Diamond Light Source’s Beamline B18, playing its role in key experiments on a daily basis. As an example, a group of Italian scientists used Beamline B18 to study dust in snowflakes that fell some 800,000 years ago – about the time of the first hominid life on Earth. Ice cores drilled from the Antarctic are made up of layers of frozen snow, dating back hundreds of thousands of years… and minute dust particles trapped as the snow fell hold key information about the earth’s climate, atmosphere and volcanic activity at the time. Using X-Ray Absorption Spectroscopy, the scientists were able to study the mineral composition of the dust, determining its origin, and unlocking clues to the changes in global climate patterns over hundreds of millennia.

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

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.

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.
