The ball drive provides rolling motion to the device. The omni-directional members are positioned proximate to and in engagement with the ball drive. The at least one motor is connected to the omni-directional members, the at least one motor providing the motive force to drive the omni-directional members and the ball drive. The controller controls the motor. The pads are positioned on the device. The device accurately mimics the unpredictable motion of a live player to provide a safe alternative to live play to increase player safety and decrease the incidence of injuries during practice sessions. ## Claims ### Claim 1 A mobile device which simulates player motion, the device comprising: a ball drive for providing rolling motion to the device, the ball drive being secured in a base of the mobile device by adjustable spring members which apply pressure to the ball drive; omni-directional members positioned proximate to and in engagement with the ball drive; at least one motor connected to at least one of the omni-directional members, the at least one motor providing the motive force to drive the at least one omni-directional member and the ball drive, the ball drive maintaining constant pressure on contact points between the ball drive and the at least one omni-directional member; a controller which controls the at least one motor; pads positioned on the device; wherein, the device accurately mimics the unpredictable motion of a live player to provide a safer alternative to live play to increase player safety and decrease the incidence of injuries during practice sessions. ### Claim 2 (depends on 1) The mobile device of claim 1, wherein the pads approximate a humanoid form figure. ### Claim 3 (depends on 1) The mobile device of claim 1, wherein the ball drive includes a single ball that is driven by the at least one omni-directional member, the at least one omni-member engage the ball to power the ball in any direction, allowing for the mobile device to have a complete range of motion and allowing the mobile device to quickly change directions. ### Claim 4 (depends on 3) The mobile device of claim 3, wherein the ball has a rubber coating. ### Claim 5 (depends on 3) The mobile device of claim 3, wherein adjustable ball casters cooperate with the ball drive, the ball casters apply pressure to the ball to keep the omni-members in contact with the ball at all times despite any eccentricity in the ball's shape. ### Claim 6 (depends on 5) The mobile device of claim 5, wherein four ball casters are provided. ### Claim 7 (depends on 1) The mobile device of claim 1, wherein four omni-directional members are provided, at least two of the four omni-directional members having a motor of the at least one motors which controls the respective omni-directional wheel. ### Claim 8 (depends on 1) The mobile device of claim 1, wherein the omni-directional members are rubber coated to increase the slipping resistance between the ball drive and the omni-directional members. ### Claim 9 (depends on 1) The mobile device of claim 1, wherein the at least one motor has bearings on either side to prevent side-loading on the at least one motor during use of the mobile device. ### Claim 10 (depends on 1) The mobile device of claim 1, wherein deep cycle batteries are provided to power the at least one motor. ### Claim 11 (depends on 1) The mobile device of claim 1, wherein the controller is a wireless controller which is part of a control system which controls the at least one motor. ### Claim 12 (depends on 1) The mobile device of claim 1, wherein the pads include high density foam around a base of the mobile device, the high density provides structure to self-right the mobile device. ### Claim 13 (depends on 1) The mobile device of claim 1, wherein the pads include low density foam in an upper portion of the mobile device used as the primary impact area. ### Claim 14 (depends on 13) The mobile device of claim 13, wherein a structural beam is provided to support the foam in the upper portion of the mobile device. ### Claim 15 (depends on 13) The mobile device of claim 13, wherein the pads are coated in shrink film or other durable coating to provide a durable finish. ### Claim 16 A self-righting mobile device which simulates player motion, the device comprising: a ball drive for providing rolling motion to the device, the ball drive being secured in a base of the mobile device by adjustable spring members which apply pressure to the ball drive; omni-directional wheels positioned proximate to and in engagement with the ball drive; at least one motor connected to at least one of the omni-directional wheels, the at least one motor providing the motive force to drive the at least one omni-directional wheel and the ball drive; a controller which controls the at least one motor; pads positioned on the device, the pads include high density foam around a base of the mobile device, the high density providing structure to self-right the mobile device, the pads include low density foam in an upper portion of the mobile device used as the primary impact area, the geometry and weight distribution of the pads cause the mobile device to be self-righting in no more than 5 seconds; wherein the device accurately mimics the unpredictable motion of a live player to provide a safer alternative to live play to increase player safety and decrease the incidence of injuries during practice sessions. ### Claim 17 (depends on 16) The mobile device of claim 16, wherein the high density foam has a density of between 4 lb/ft3 and 6 lb/ft3. ### Claim 18 (depends on 16) The mobile device of claim 16, wherein the low density foam has a density between2 lb/ft3 and 4 lb/ft3. ### Claim 19 (depends on 16) The mobile device of claim 16, wherein the pads approximate a humanoid form figure. ### Claim 20 A mobile device which simulates player motion, the device comprising: a ball drive for providing rolling motion to the device; omni-directional wheels positioned proximate to and in engagement with the ball drive, at least one of the omni-wheels engage the ball drive to power the ball drive in any direction, allowing for the mobile device to have a complete range of motion and allowing the mobile device to quickly change directions; at least one motor connected to the at least one omni-directional wheel, the at least one motor providing the motive force to drive the omni-directional wheels and the ball drive; adjustable casters spaced from the omni-directional wheels, the adjustable casters cooperating with the ball drive, the casters having tension springs which force the ball into contact with the omni-directional wheels to keep the omni-wheels in contact with the ball drive at all times despite any eccentricity in the shape of the ball drive; a controller which controls the at least one motor; pads positioned on the device; wherein, the device accurately mimics the unpredictable motion of a live player to provide a safer alternative to live play to increase player safety and decrease the incidence of injuries during practice sessions. ### Claim 21 A drive system for a mobile device, the drive system comprising: a ball drive for providing rolling motion to the mobile device; omni-directional members positioned proximate to and in engagement with the ball drive; at least one motor connected to at least one of the omni-directional members, the at least one motor providing the motive force to drive the at least one omni-directional member and the ball drive;
