1. An exoskeleton wheelchair system, comprising:
a base;
one or more wheels coupled to the base;
a body support connected to the base, comprising:
a back support; and
one or more leg supports pivotally coupled to the back support; and
a gait wheel linked with the one or more leg supports via one or more gait linkages and configured to rotate in association with the one or more wheels,
wherein the one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode,
the back support is maintained at a fixed position relative to a location of the base when the one or more leg supports pivot about the first axis while the back support is in the standing position mode, and
one end of each of the one or more gait linkages is pivotally connected to a contour of the gait wheel.
