Raspberry Pi Ball Juggling Robot
This is a Raspberry Pi Ping Pong Juggling Robot. It's still in the making. But here's some first footage. It uses the Raspberry Pi camera module NoIR to get the realtime ping pong ball position. Because the Algorithm for doing something like this in real time (90 times per second) has to be really small, it only works in a dark room at the moment. This way the Raspberry Pi only has to look for bright pixels and that's it. It uses some kind of very simple computer Vision. No OpenCV. That would be too heavy anyway.
The Stepper motors are Nema17 Steppers! It Also uses the Arduino CNC-Shield with A4988 controllers.
The Arduino Stepper Motor Controller uses the great grbl software! here a link:
