A simple translational robotic arm that I built that emulates the user's input in real-time, similar to a Hot Cell arm or ROV robotic arm. The microcontroller is a PIC18F27Q10, and the servos are 3 x 10kg (waist, wrist, gripper) servos, and 3 25kg (shoulder, 2 elbows) servos. Powered by 2 18650 cells. Printed in PLA
