This part focuses on assembling a simple prototype robot arm using small wooden rails, plastic pins for support, 2x MG996 servos (base and elbow) and one MG90 as a wrist. For the circuit design, my lab partner and I used potentiometer sensors, Arduino Uno and a main power supply for the motors.
In the video below, it shows how the robot reacts and maintains safe operation limits by raising the wrist respectively with the motion of the elbow
