<p>A training system (10) has three programmable robotic ball shooting machines (20)(30)(30) that communicate via link (50). The communication link (50) may be a conductor, such as a cable, or alternatively, the communication link (50) may be wireless. Each of the robotic ball shooting machines (20)(30)(40) is provided with a protective housing (52) which is shaped to deflect tennis balls and each is supported on wheels (54). A remote control device (60) is provided with control buttons (62)(64)(66) for selectively commanding any one of the plurality of ball shooting machines to fire the next shot of the programmed shot sequence.</p> |
