Abstract: An apparatus has a chassis that has a pair of rear wheels that passively rotate and a pair of front wheel sets. Each pair of front wheel sets has an upright with an affixed motor. A front wheel is fixed relative to the upright and engages with the motor. A linkage connects the chassis to each of the uprights and is configured to move the uprights in a first range of motion. A linkage actuator actuates the linkage.
