ABSTRACT:
A table tennis robot with right and left servers, oscillatory motion, top spin and bottom spin, right and left side spin, combination of spins, or no-spin modes, variable ball speeds, and continuous recycling of balls, to provide a human player with challenging practice serves.
A ball catching net is located at one end of the tennis table. Balls caught by the net fall into a pan located below the table and are then fed upward by suction of a fan into a chamber. The chamber distributes balls one at a time into a vertical tube. At its bottom, the tube has right and left branches. A ball deflecting vane is adjustable to selectively direct a ball into either the right or left branch. The branches lead, respectively, to a right server and a left server. Each server has a rotating ball drive wheel. The output port of the right server has adjustable guide rails to impart high top spin to a ball. The output port of the left server has adjustable guide plates to impart various types of spin to a ball. The robot is oscillated about a vertical axis by a drive motor.
