This was cheap robotic arm project. The robotic arm had 7 dof. It consists of cheap pwm servos, 3D-printed flames and arduino uno. The movie shows endpoint control using a gamepad.
This work was inspired by real life ATARI Pong project. We were able to make it in time for the school festival, despite the tight budget and schedule. We were a team of two, but it was first time to work as a team for me, so it was a good experience.
