maxon motor have developed the Exoskeleton Drive GEN.1 for use in hip and knee exoskeletons.
The global Exoskeleton market is growing in both market share and technological developments at a rapid rate each year. Maxon motor have several global customers we have worked with to develop brushless DC motor solutions for use in robotic limbs.
Available from the beginning of October 2017 is a complete joint actuation unit consisting of a pancake brushless DC motor (EC90 flat) with inertia optimised rotor, Internal high resolution 4096 MILE Encoder, planetary gearhead with absolute encoder and EPOS4 position controller with CAN and RS232 interface. Fitting the 17bit SSI absolute encoder directly at the joint rotation to a degree will negate the effect of gearhead backlash giving designers increased positioning accuracy. The unit will deliver 54Nm of continuous torque and 120Nm on a 20% duty cycle. The system can be operated on supplies between 10 and 50V DC and the actuation speed is up to 22rpm.

A complete relaunch of the tendon controlled soft Robot, Roboy, is planned for 2018.
Reported here in 2013, Roboy was the first-of-its-kind Humanoid Robot developed by the University of Zurich. What set Roboy apart was the tendon-operated “soft” robotic features. As a main project partner, maxon motor supplied 48 brushless DC motors, gearheads and controllers that enable Roboy to move in a precise manner. Roboy now lives permanently at the Technical University in Munich where development is focused on enhancing A I. This is where the concept of Roboy 2.0 was born, utilising Roboy as a foundation to create robots that not only move like people but will think like people. At this stage Roboy is unable to stand or walk. Roboy 2.0 will be a complete relaunch and the new version will be able to stand, thanks to development of the legs and components like software, DC motors and technology, it is hoped that by 2018 Roboy 2.0 will stand on his own two feet and interact with us.

A robot operates the opposing player rods on a Foosball table and has won against human players.
The Swiss Federal Institute of Technology (EPFL) has developed a foosball table with autonomously operated robotic rods. The table has a transparent playing surface with a camera that locates the ball by taking up to 300 images per second. These images are immediately evaluated and sent to control the rods, which are powered by maxon EC-4 pole DC brushless motors with gearheads and motor controllers. The rods stop the ball and aim for the goals. The students aim to make the robot even more intelligent by programming the robot to analyse opponents players, find gaps in the defence and predict the ball’s trajectory.

Dutch company Preceyes developed a world first robotic system for retina disorders, using haptic feedback and maxon DC motors.
Detached retina surgery requires precision to an nth degree where the stability of human hands are no match compared to robotic systems. This is why Dutch company, Preceyes, developed a completely new robotic system for eye surgery. Especially designed for the treatment of retina disorders, the robotic device improves precision up to 20 times more than a Surgeons hand, making operations once deemed impossible due to lack of precision now being successfully performed.
Surgeons operate via a joystick while looking through a microscope. The joystick controls a robotic arm, controlled by maxon DC motors, assisting surgery in millimeter increments. A haptic feedback function allows the surgeon to see and feel their actions and the robotic system supports quick retooling. This is an important factor because it reduces operation time bringing a multitude of benefits to the patient.
