The 2018 Junior RoboCup Competition was a success for the teams from Fort St High School and maxon were proud to be on board.
maxon motor Australia were delighted to sponsor Fort St. High School in this year’s Robocup Junior competition. The team competed in two divisions; Rescue, where robots navigate an obstacle course to locate and rescue a victim, and Soccer, where four robots contest each other in a game of soccer.
Fort St. High School have extensively used maxon DC motors particularly the DCX 19S and A-Max motors, selected for their excellent power-torque ratio. The A-Max motors proved useful in Open Rescue, being used as part of a claw mechanism due to the high torque and thus grip. The DCX19S were used in the Open Soccer robots.
At the NSW State Competition, the School teams achieved excellent placings:
- 2nd Open Rescue: Mars Rover
- Rescue Innovation Award: Mars Rover
- Rescue Innovation Award: PATANEtial Nationals
And at Nationals (Melbourne) the School received the Award for Best Robot Design for Open Rescue: Mars Rover.
maxon is proud of the achievements of all of the students that entered the competition and recognises the hard work and dedication from the teams and teachers, and all supporters who help to invest in the engineers of the future.

Almost one year to this day 15 years ago, NASA Rover Opportunity embarked on its journey to Mars.
NASA Engineers have been trying to reach the Opportunity Rover in recent weeks, however due to a heavy and persistent sandstorm they haven’t been able to make contact. It’s assumed the batteries have fallen below 24V causing the machine to enter into standby mode. It needs sunlight to recharge the batteries to “wake up” the computer and resume communications.
Opportunity’s six wheels are driven by maxon DC motors. There are 35 drive systems with diameters of 20mm and 25mm for the rover. The maxon motors in the wheels, for example, did more than 78 million revolutions each, under extreme environmental conditions and temperature fluctuations from -120 to +25ºC. The practicalities and knowledge from this successful project are being transferred across developments of new motors that will soon fly to Mars on forthcoming missions by NASA and ESA. “Opportunity has braved many minor and major sand storms over the years and has always managed to recover its energy. We have no doubt that our motors will also run without trouble afterwards,” says maxon CEO Eugen Elmiger.

maxon brushless frameless DC motors are used in a semi-autonomous prototype that can hop upstairs.
A robot that can balance and move on two wheels is being developed by a team of students at ETH Zurich. Named the Ascento, it is a bi-pedal robot that adapts to different environments and terrains with the explicit purpose to hop upstairs. Similar to a Sedgeway the centre of gravity is above the axis thus the robot can balance on two wheels and move, as long as it is powered by a controlled device. Equipped with sensors the Ascento can 3D scan a room and calculate the required height and length of jumps to take. Powered by two maxon EC 90 flat brushless frameless DC motors in the wheels, the motors give high torque and precise control that allow a jumping and balancing action, such as that of landing on a narrow step. maxon deliver the rotor and stator separately without an output shaft. This gives the researchers the flexibility to integrate the DC motors into the application and joint structure without compromising on space. Each motor is driven by a compact EPOS4 module motor controller. The potential for the prototype is in building inspections that are at risk of collapse or on fire, for example.

Global DC motor and drive specialist maxon motor has recorded growth across innovation, markets, revenue and production in 2017.
Sachseln/Obwalden (Switzerland) – The maxon motor group accomplished record revenues in 2017reporting a rise by 8.6% to CHF 459 million (up from CHF 422.5 million in the previous year). All markets contributed to the growth. Cash flow increased to just under CHF 50 million (up from 41.7 million). The number of employees globally increased to 2577. At a 40% revenue share, medical technology continues to be the strongest sector, followed by industrial automation at 28%. With R&D investments of CHF 34 million and more than 360 employees in our R&D sites worldwide, maxon has succeeded in bringing more than 20 new motors and gearheads to market and expand the company’s position as a leading manufacturer of high-quality drive components and systems. maxon looks to the future with confidence.
The impetus of growth behind maxon is mainly from the innovative precision DC motors and drives with high efficiency as well as the matching electronics for controlling complex motion sequences. The company produces in Sachseln/CH, Sexau/GER, Veszprém/HU, Cheonan/South Korea, and soon at its new factory in Taunton near Boston/USA. In addition to the sites above, R&D facilities are also located in China, France, and the Netherlands.
Growth in all markets worldwide
The biggest market in Europe is Germany, followed by Switzerland and the UK. Italy and the Iberian peninsula also grew markedly. After some years of stagnation, a strong growth has also picked up in the US. In Asia, maxon achieved new records in Japan, South Korea and Taiwan. In China, maxon has seen double-digit growth over the past years. “The revenue increase by 100 million over four years has posed a great challenge to us as a company in regard to quality and service. Owing to our highly trained employees, we have been able to master this challenge successfully,” says majority shareholder Karl-Walter Braun.
20 + new products released in 2017 alone
One in seven maxon employees works in research and development. As a result of these steadily expanding capabilities, maxon launched more than 20 new electric motors, gearheads, encoders and controllers in the past year. In aerospace, the motors work at temperatures as low as -130°C, while ESA’s Mercury Planetary Orbiter space probe has to withstand temperatures of more than 350°C on its flight toward the sun. In 2020, high-performance maxon motors will be used in two rover missions by ESA and NASA, after having run for more than 15 years in the hostile Mars environment despite a scheduled service life of only a few weeks.
“Our ‘Mission 2020’ strategy for growth, which we launched years ago with the goal of achieving forward integration of drive systems, is showing some initial success,” says Eugen Elmiger, CEO of maxon motor group. “For example, we’ve been able to secure a large order for pump systems to reduce nitrous gas emissions in Diesel cars in the highly competitive automotive market. We also drove forward the development of complete surgical power tools, as well as micro-pump systems used in minimal invasive cardiac surgery.” Eugen Elmiger also expects healthy growth for the user-friendly and efficient high-performance multi-axis controllers made by zub, a company acquired by maxon last year.
Looking ahead: a strong start
The first months of the new year were characterised by strong growth across the group. Pending orders and revenues exceed the figures of the previous year. Due to the overall economic development, the company expects growth to slow down somewhat in the second half of the year. “We will approach further expansion with the necessary caution,” says Karl-Walter Braun.

Research and development into the spinal cord has taken an unconventional approach at The Swiss Institute of Technology.
Our brain is the central processing unit of our motor skills and functions. But it does not control our physical movements alone. The contribution that our spinal cord makes to our physical actions has driven two investigative questions from a team at the Swiss Federal Institute of Technology in Lausanne – How do these motor circuits work and what is the underlying control mechanisms for the movement of vertebrates? To better understand the secrets of the spinal cord, they have a dedicated Lab, called the Biorobotics Laboratory or Biorob for short. Here, they build robots to better understand mobility in living beings, drawing inspiration from many different animals where motor control happens mostly in the spinal cord. From this they built a robot called the Pleurobot, based on a Salamander. Powered by 27 maxon brushless frameless DC motors the robot can move on land and in water seamlessly mimicking the actions of the amphibian. Primarily its use is to assist with understanding how the nervous system in a spinal chord operates and will assist research in the neurosciences and biomechanical fields contributing to neuroprosthetics and paraplegia therapies.

For many, many years nature has inspired engineers in evolving and enhancing technology to create powerful and proficient robots. Here are some examples of current creative developments.
Birds, Dogs, Snakes and Elephants are just some of the animals inspiring mechatronic engineers to design state of the art robots. Here maxon takes a closer look.
The bionic bird A French company has developed a bionic bird toy that can be controlled with a smartphone. A lightweight 9 grams, the bird can achieve speeds of up to 20 km/h and has a range covering more than 100 metres. The bird presents an alternative to propeller drones.
ANYmal Engineers at ETH Zurich developed a four-legged robot that was made for very harsh conditions and can move autonomously. Since its inception in 2009, ANYmal has evolved into machine that can conquer inclines, run, jump and press elevator buttons. Using laser sensors and cameras, the robot continuously creates a map of its terrain, knows where it is and navigates through the changing landscape. Weighing around 30 kg it can carry a payload up to 10kg and run for 2 hours on a fully charged battery. The future use for the ANYmal is expected for inspections, rescue operations or the entertainment industry.
The underwater snake
A modular underwater robot snake has been developed for use in inspections, maintenance and repair work reaching distances and places that conventional underwater robots are unable to reach. The robot is flexible and has moving connecting parts with the option of mounting tools. Inside the connecting modules are maxon brushless DC motors with customised gearheads. The underwater robot has been in constant development for 10 years with the current model reliant on a cable. Future versions include keeping the robot on the bottom of the ocean indefinitely at a docking station from where it can launch into action when needed.
This robot was named so because it moves like a snake. With a diameter of 6cm it can fit into narrow spaces making it suitable for inspection in unstable environments such as after earthquakes. With independent modules the SnakeBot can also climb up plant legs and posts. There are approx.. 20 maxon EC20 flat brushless motors in the snake, selected for both their high torque and ability to withstand short periods of overload.
This robot is modelled on an octopus’s tentacles and elephant’s trunk. With skin made of innovative fibre technology this robot offers flexible movement that can bend in three different directions at the same time. The robot is pneumatic and lightweight with 12 degrees of freedom and can carry up to three kilos of payload.

Biology and engineering have been combined to create the world’s first prosthetic foot with propulsion powered from a maxon DC motor.
Our calf muscles provide the essential power, control and stability for walking. Those who’ve had below the knee amputation tire very quickly walking on a prosthetic foot. Step in Hugh Herr, Professor at MIT Boston who developed The Empower bionic prosthetic foot along with the Ottobock Group, a world-leading supplier of prostheses. Hugh himself is a double transtibial amputee resulting from a mountaineering accident. Hugh and his team drew inspiration from nature to create The Empower combining both biology and engineering together.
The Empower is a third generation newly developed bionic foot. A research team spent 16 months to make walking feel more natural by using a carbon spring which transfers energy directly to the foot. A powerful maxon DC motor refines the energy pulse delivered by the spring and provides the missing power of a calf muscle, step by step with each toe push-off. Several sensors “tell” the prostheses which phase of movement the foot is in, at any given time, so that it can perform the corresponding action. This allows for short sprints, which were previously deemed impossible, as well as walking on uneven ground and up inclines. What’s more, the greater the load on the prostheses, the greater its energy output becomes, just like a natural foot. The DC motor providing the propulsion is maxon’s EC-4pole 30. Selected for its powerhouse features and high output per unit of volume and weight it provides an ideal ratio between size, weight and power – a key factor in developing prosthetics.

Prosthetics are a significant engineering challenge because of their conflicting DC motor design goals: high torque, high speed, compact size and the DC motors need to be as energy efficient as possible.
German company Vincent Systems have created a bionic hand prosthesis that is the first commercially available prosthetic delivering haptic feedback about grip strength to its wearer. This is achieved with short pulses of vibration. If the hand were to vibrate evenly, a person becomes familiar to the sensation and eventually stops paying attention to it.
What sets this prostheses apart is that each finger can individually open up. This opens up numerous situations for the wearer such as being able to ride a bike, tie shoelaces, hold a raw egg or open a door. 12 grip patterns are available that can be activated via muscle contractions. Weighing about the same as a human hand it’s available in a version small enough for children, with the youngest wearer being eight years old.
Each individual finger is actively driven by a DC motor, and the thumb is driven by two DC motors. Maxon have up to six brushed DC motors in the hand: DCX 10 DC motors with modified GP 10A planetary gearheads. The drive systems were selected for their compact size and highest energy density currently available from maxon. Plus the drives needed to be durable and function faultlessly for approximately five years while being exposed to diverse and heavy strain every day.
It was important to CEO and founder of Vincent Systems, Stefan Schulz, that patients wouldn’t need their healthy hand to help. “A prosthetic hand should help its wearer and not demand the attention of the good hand.”

Brushless flat DC motor with hollow bore for air and light transmission.
Today we exhibit a new motor development featuring a Brushless DC (BLDC) flat motor. Flat motors are also commonly referred to as pancake motors. This unit has a body length of just 38mm and an output power of over 157W and 6000rpm at the shaft in the application. The average motor power rating for the series across 6 variants is 100W. The overall motor diameter is 68mm and it can be supplied with or without protective covers for IP rating. The motor is available with an internal encoder with resolutions up to 16,384qc per revolution making it suitable as a rotary stage of robotic joint actuator. The unique feature though is the motors hollow shaft. This is to enable customers to pass light or air through the bore of the motor. Air transmission is a common requirement for packaging and placement machinery and light or fibre is a common requirement for film and camera gimbal applications. This motor was also manufactured with the customers shaft length and bore specifications in combination with a custom rear shaft extension at the rear from the motor rotor.
