Robot arm

thingiverse

I created this robot arm design several years ago, inspired by Simone Giertz's soup robot. At that time, I didn't have a 3D printer yet, so I built the first version out of foam board and later upgraded it to wood. Now, with my 3D printer up and running, this was the first project I tackled. The design centers around three 9-gram servos, which I connect to a standard RC receiver and controller. To accommodate my warped bed, I printed each component separately, as large surface area prints often don't turn out well. For better results, I recommend using supports for the box part, as it features tiny overhangs near the pin.
