Omni-directional treadmill

摘要

A treadmill having a track assembly that allows a user to walk or run in any arbitrary direction. A movable user support has a plurality of rotatable members that rotate about axes normal to the direction of movement of the user support. Separate power driven mechanisms concurrently move the user support and rotate the members to omni-directional user movement. A control for the power driven mechanisms is responsive to the directional orientation of the user on the user support to cause the user support to operate in the direction of the orientation of the user.
