Design and implementation of an electromyograph with a module for independent control of the fingers in an artificial hand

In this research, we try to set up a simulated handrobot with the aid of the electromyogram signal. The signalreceiving process and its use as a robot s stimulus consists ofvarious parts, including amplifying blocks, filters and signalsynthesis, continuous signal conversion into digital signal anddriving the motor to control the robot hand.The results and experiments show that electromyogram signal isin the range of 10 to 250 Hz, and the amplitude of this signal liesbetween 0 and 5 mV-peaks. In this essay, we have designed andimplemented some circuits to detect and display this signal. Inaddition, we used the received signal to control the robot hand.The design steps and the various components of the robot arediscussed. All the circuit simulations and printed boards werecarried out in Proteus and Altium Designer. The AVRmicrocontroller with Code Vision compiler is applied forprogramming.
