US Patent 8721476 Interactive basketball trainer

This invention presents a basketball training device which resembles a mannequin that defends against basketball players with a series of blocking motions. When a proximity sensor detects an approaching player, a control unit initiates waving of forearms, raising/lowering of upper arms, chopping motion of arms and torso raising and lowering. An audio circuit plays music or realistic background noises. When convex bottom of primary base is placed on a floor, weight of ballast and rechargeable batteries allows the device to return to an upright position when tipped. A gyroscopic unit within a control unit can activate when the device tips to ensure return of the device to an upright position. Alternatively, the unit can be placed with the secondary base, which features castors that allow the unit to roll when stuck and facilitates placement on a basketball court.
