Abstract:
A data acquisition and control system for a 2 DOF platform for testing of transfemoral
prosthesis is developed. The system is based on a PC with an attached motion control
setup where target position trajectories are loaded for both the human hip vertical motion
and the thigh angular motion. A servo motor is actuated to move a carriage in vertical axis
tracking the motion profile of a human hip. Another servo motor attached to the carriage
is actuated to exhibit the angular motion profile of a thigh. A prosthetic limb can be
attached to the carriage. Upon simultaneous actuation of the two servo motors the
prosthetic limb can be moved exhibiting the gait cycle of a human leg.
