A challenging robot, perfect to have fun and learn robotics at the same time

Controlled by your own smartphone using the free AIR HOCKEY ROBOT APP

This is a mostly 3D printable air hockey playing robot that, in addition to moving across the required two dimensions, can predict the movements of rebounding pucks and attack/defend in consequence.[space size="5px"]
