Playing ping pong is not fun without a partner. With the Omron Table Tennis Robot, you will always have a partner to play against. The machine not only plays against humans but calculates easy-to-hit positions, so you can keep rallies going. The robot recognizes your standing and paddle positions to analyze the position of the ball in 3D and predict its trajectory.
The robot uses data from its sensor to move the paddle and keep the game going. It has a fairly decent impressive rate. The above video shows it in action.
