The disclosure is generally directed toward vehicle support systems. In
one embodiment of the invention, first and second support assemblies can
be pivotally coupled to a base. A control mechanism can couple the first
and second support assemblies together and be configured to control
pivotal movement of the support assemblies between spread and stowed
positions. In another embodiment, first and second support assemblies can
be pivotally coupled to a base and to first and second wheel assemblies.
First and second steering mechanisms can be coupled to the first and
second wheel assemblies and the first and second support assemblies. A
control system can be operatively coupled to the first and second
steering mechanisms and can be configured to command selected angular
positions of the first and second wheel assemblies relative to the base
by compensating for the support assemblies being in various positions.
