dountsorelse made this robot arm to huck candy at passersby. The inspiration was social awkwardness at conventions but the arm could also be called into action for parades, trick-or-treaters…doctors office(?). It uses a camera, Raspberry Pi 3, and a distance sensor to single out who does and does not get candy

Doing the Candy Throwing Thing
Now for the part that makes the project interesting. The goal was to throw candy, so my thinking was that I’d record all the movements as I walked the robot through the process. Then, I’d play them all back and we’d be all set. As hinted at, I had a couple points of confusion between the calibration and the threshold and tried quite a few iterations before simplifying things
