Abstract

In this research project, we aimed to design and implement an upper limb prosthesis controlled by myoelectric signals using a digital signal processor platform. To emulate the seven main movements of a human arm, a robotic arm was produced that was capable of using the control signals generated by a human arm, where we captured the electrical pulses to design a silver/silver chloride contact type surface electrode using a plating process in a chemical laboratory. This method is an alternative technological support for amputees or partially paralyzed muscles, which typically remain intact so they can exercise control. The signals produced by these muscles can operate a prosthesis or a robotic device. Therefore, the prototype arm design process comprised the following steps. The dimensions and joints of a human arm were determined and reproduced as a robotic arm, where software was designed to run simulations of the robotic arm to make corrections before the final prototype design was produced. The robotic arm was implemented according to the specifications obtained and a motor control circuit was produced to replicate each of the seven movements of the robotic arm. Finally, a validation was performed for each of the movements performed by the robotic arm by considering the position, speed of flexion, and extension of the joints.
