Air Hockey Robot – a 3D printer hack

A 3D printer is the first robot that most people will own. With the decreasing costs of components, open source designs, and advanced software, it is going to kickstart a whole bunch of other robotics projects like this. The technology is becoming accessible.

This is really freaking cool. That's all I've got.

I thought the AI was just following the puck continuously but turns out it's actually figuring out what the trajectory will be based on the angles the puck is traveling in. Very cool.
