As a fan of robots, videos, and pucks, I was mesmerized by this project. It’s a a cool 3D printer hack that allows you to play a robot in a rousing game of air hockey. The system uses a computer vision component to see where the pucks is, send it back to the opponent, and even set up shots when it loses.
The creator Jose Julio wrote that his daughter loved air hockey and wanted someone to play with. Instead of helping her make friends, he used parts of a 3D printer and a PS3 Eye connected to a PC to handle video capture and analysis.
