Servo Robotic Arm

A small robotic arm with 4 degrees of freedom and a gripper, made out of aluminium brackets and SG90 servo motors. The control unit consists of Arduino Nano and 5 potentiometers, used to control the movement of every joint.

The base is made out of two aluminium circles. One of them has a hole drilled in the middle which enables servo to be attached and control the arm sweep motion. All cables from servo motors are wired to a protoboard where an 8-link cable is attached, which connects the control box.
