The brushless flat motors from maxon meet all these criteria. In total, four maxon EC 45 flat motors (70 W) are used in the robotic legs, in combination with the GP 42 C planetary gearhead (ceramic) with MILE encoder.
Manmeet said, “We found that the motors from the maxon EC Flat series were the best for size and power density. The planetary gearheads with ceramic gears also provide exceptionally high torque, and can withstand varying output torques.”
Worldwide, there are now about 100 children using the Trexo walking robots. With every new child who uses the Trexo, the walking robot undergoes further improvement. This is achieved above all through close collaboration with the parents.
Luz’s mother Caro said, “Trexo is giving us so much hope because as a parent you are told all of these things your child will never do. Trexo has changed that.”
