Robot arm design controlled by EMG signals

It is obvious that there are various prosthetic hand and arm structures today. This type of EMG-controlled robot arms perform the movement by appropriately processing the signals they receive from the muscles. The important thing is to process EMG signals and choose the most suitable method for this. A total of six electrodes are used in robot hands with two movements (wrist movement and hand opening and closing movement), mostly to capture EMG signals in the muscles. Three of them are used only for wrist movements, and the other three are used for hand opening and closing movements. The number of electrodes to be used in this project will be different. It will be shown that the same movements can be achieved with fewer electrodes. With a suitable EMG signal processing circuit, signals are transmitted to the ADC end of the processor, thus ensuring the proper movement of the motors. In this way, improvements can be made in the structures of today's prosthetic hands and the cost can be reduced. In other words, in this thesis, it is aimed to demonstrate the processing and use of EMG signals with a method different from the methods used today.
