Life hackers rejoice! A new idea has hit the field, and it is awesome. Jose Julio designed this robotic competitor for his daughter using a 3D printer and a PS3 EYE to monitor the movement of the puck. Using a program he wrote from scratch for the project, Julio was able to provide different strategy levels, including offensive and defensive behavior algorithms for the robot to use.
You can read his blog to find out how he did it in more detail, and you can see a video of the functionality below. Happy hacking!
