Abstract: A gantry system supports a human user in a harness attached to a carriage on a track. The carriage may comprise a body defining a U-shaped or C-shaped opening sized to receive a cylindrical track, and a pair of wheels attached to the body that roll along a top portion of the track with sufficiently minimal drag to permit the user to move the carriage without assistance. Single track embodiments may have a straight or curved trajectory and may have intersecting track portions with junctions that move between the intersecting track portions. In other embodiments, the carriage traverses a perpendicular track spanning a pair of parallel tracks. The perpendicular track may traverse the parallel tracks with or without motorized assistance. A counterweight system may provide partial weight support for the user. In one embodiment, the tracks are supported by a collapsible free-standing structure.
