摘要:
A motor-driven roller disc for multi-directional operation under the control of a user, with a multi-wheeled drive configuration with motorized direct-drive power-train to give a user the ability to move in any direction at any time, and to maintain control over steering and speed when in motion. The roller disc includes a platform having an array of radially-oriented wheels mounted around the underside perimeter, and a central pivot wheel mounted at the center of the underside. The central pivot wheel maintains a slightly higher clearance than the perimeter wheels, enabling the user to engage a desired perimeter wheel by shifting his/her weight towards it, thereby making contact with the ground. All of the perimeter wheels are connected to a common flexible/jointed axle that encircles the disc, the axle being driven by a battery-powered DC motor. The user controls the speed of the motor by a remote hand-controller such as an RF remote control, and maintains control over direction by shifting his weight about the pivot wheel to achieve traction with a desired perimeter wheel thereby allowing motion in that direction.
