MCU-Based Robotic Elbow Movement Control

This paper proposes an MCU based robotic elbow movement control. In recent years, a lot of research has been developed in alignment with mimicking body movement especially in the field of medical and industrial applications. Robotic movement has different implementations. The usual method is through PID controller. However, implementation is complicated, response is slow, and movement control is delayed. Speed is also a problem causing the human arm and robotic arm not synchronized with their movement. In this paper, the fuzzy logic method is substituted to PID control. The MCU is used in the implementation of robotic elbow movement. The Experimental results are now carried out to demonstrate the effectiveness of the proposed technique and method. Results show that the proposed method is preferable and better over the conventional PID from response, delay, and also the movement control through three variable speed controls. Also, the movement control of the robotic elbow do synchronized with the human arms with negligible delay. In conclusion, the application of microcontroller does improve the movement of the robotic elbow. The switching response is faster and the delay is minimized caused by the PID control.
