Abstract
A universal adjustable-position mobility device for multiple use applications including robotics, industry and handicapped mobility facilitation. The device can be used to transport objects across varied terrain including inclines and declines and by utilizing a sliding extensible track system can bridge obstacles and traverse mud, sand and snow. The device further incorporates features which allow raising and lowering of the center of gravity of the load. By extending the rear wheels, the angle of the track mechanism relative to the ground to can be adjusted to facilitate engagement of the tracks with an abrupt incline such as when loading a wheelchair onto a vehicle.
Claims20
