“Taking big steps towards full mobility”

In the hip and knee joints of the MARCH II exoskeleton, high precision and great forces come together. One of the requirements for the joint design was that the distance between the magnetic encoder ring and the sensor should not exceed the boundaries of 0.1 mm and 0.3 mm. The sensor reads out the angle of the joint, so when big forces are acting on the joint, only minimal deformations can be allowed.
