Spanish hacker converts his 3D printer into an air hockey-playing robot

Hacker Jose Julio loves robotics and says his daughter loves air hockey. One day, he decided to build her an air hockey robot out of 3D-printer parts and a PS3 camera to make sure she could always play the game. This is an amazing achievement: the robot doesn’t just move in two dimensions. It can also predict the puck’s movements, decide whether to block or shoot, and is adjustable in difficulty.
