Abstract: A folding net structure for attachment to a table tennis table and for feeding balls to a robot ball server. The net structure includes a plurality of elongated arms, each arm extending radially from and having one of its ends pivotally attached to a central member which is positioned at a lower central portion of the net structure. Netting material is attached to each of the arms such that the netting is maintained in an open and extended position when the arms are moved to their extended angular positions. The netting material has its lower edge attached to a trough device for receiving balls falling from the netting. The trough has a central point thereof pivotally attached to the central member and being operatively attached to the robot server to feed balls to the server.

Abstract: A portable, automatic serving device for table tennis is provided which includes a robot server and ball capture net. The robot includes a serving head which is mounted for rotation with respect to the body along a plurality of axes. The head is provided with balls from a passageway in the robot operatively connected between the head and the base of the robot. A collapsible net is provided for capturing balls returned by a player. The robot is positioned within and cooperates with the net so that return balls are fed automatically to the head. The robot is operated by three motors, which may be controlled individually to serve sequentially a plurality of balls to a player for practice or for sport. The robot construction provides for a variety of ball delivery techniques, all of which are controlled simply during operation.
