Abstract
In recent years, the number of people requiring motor rehabilitation treatment in the lower limbs has increased. Due to the high number of patients and the long time the treatment demands, the use of robotic devices can increase the efficiency of rehabilitation treatments. In this context, we highlight the use of robotic orthoses. This work presents the development of proposals for activation and position control of an active lower limb orthosis, dedicated to the accomplishment of the movement of extension and flexion of the human knee. The mechanical structure of the device was developed at the Federal Institute of Espirito Santo and has a DC motor as actuator, responsible for the execution of the movement. The developed proposal uses electronic sensors of position and limit of course, electronic circuit in closed loop and PID control.
