Selection of electric driving modules for orthotic robot

Driving modules of orthotic robots are employed for moving paralyzed limbs of the disabled. They operate under strongly variable loads disturbing realization of the desired motion profiles to be reconstructed at the driven human joints. A way of selecting an electric driving module for an orthotic robot, designed and built at the Warsaw University of Technology, is discussed. The presented works suggest that selection of driving modules for orthotic robots, which are to meet rigorous functional and operational requirements, is not possible unless a simulation model study is carried out.
