Shaun Slifer and Stuart Anderson have constructed a tumbleweed juggling robot for the Rossum's robot arts collective show, "Mechanosphere", at the Three Rivers Arts Festival gallery in Pittsburgh. It uses an infrared security camera modified with a IR long-pass filter and retroreflective tape to track the tumbleweed. Position and velocity data from the vision system are processed into motor commands and sent to an Arduino and Sabertooth that control the motion of a gimbal mounted platform built from recycled bike drive trains, EMT conduit, and canvas.
