Abstract :
The Artificial Hand Project is a cross disciplinary cooperation project group that has the vision of building an artificial hand that will be accepted by the bearer as a part of the body and not as a tool as it is today. The investigation of a control system for such an advanced prosthesis is carried out in this paper using a simple motor system, the spinal withdraw reflex system on a rat. Electromyography measurements on a single rat performing 110 reflex movements have been conducted. Several electrodes localized in different muscles on the rat´s hindlimb and an artificial neural network (ANN) have been used to classify movements induced by stimuli on the skin of the rat paw. Different receptor fields are stimulated at the same time as the EMG measurement is processed by the ANN, which have the task of recognizing the origin of the stimuli
