A Method of Semiautomatic Control for an Arm Prosthesis

Resumo

A method of semiautomatic control of a full arm prosthesis is proposed. The arm prosthesis is viewed as a robotic manipulation system equipped with a pointing device determining the position of an object among others, a position sensor, and a microcontroller. In this regard, the translational motion of the prosthesis hand is done in the automatic mode, while its orientating motion is accomplished in the tracking mode by moving the foot with a master controller located in the shoe. A functional diagram of the control system is proposed along with an algorithm for controlling the motions.
