Abstract:
The human prosthetics is a major lack in our surrounding, while the technical capabilities are capable for its availability. Thus a control system for a prosthetic human arm that functions by mirroring the movements of an existing arm is the aim of this project. An arm that reflects the other one to make daily tasks easier for the amputees, with the capability of sensing excess heat and force applied on it to offer protective reaction. This thesis uses electrodes sensors to sense the different moves of the arm. The signals from electrodes through a pickup circuit will be passed to microcontroller to translate those signals to the motors. A programmed microcontroller is used to control the behavior of the arm. Different sensors are used to sense different physical signals such as temperature and force. According to the signals from those sensors the microcontroller will control the arm. The simulation for the system carried a fair degree of freedom for shoulder, elbow and wrist joints, to simulate the mirroring of the movements. The obtained result from the simulation is encouraged for more research in this area.
