 Robot Air Hockey


 Air Hockey is a fun game, fast paced and can be very challenging with a seasoned opponent. What happens when you build a robot that can move faster than you and calculate where the puck will travel? A robot that is tough to beat!

“One of the main problems I’ve had is that the power of the NEMA17 motors are pretty fair for this project and the disadvantage of using stepper motors is that if we lose steps (which can easily happen, for example when the robot hits the puck against the wall) and we do not take into account the missing steps we lose the position of the robot. To fix this, what I’ve done is to use the vision system to detect also the robot (with a different color) so we can detect when the robot has lost steps and fix it.”
