Abstract
A toy vehicle reconfigurable between unfolded and folded configurations includes a generally body pivotally supporting a pair of generally planar driving systems on either lateral side. Each driving system includes a motor and gear train driving a continuous track passed over multiple pulley wheels. One pulley wheel of each driving system is carried on an arm mounted to a frame of the system so as to pivot between retracted and extended positions and spring loaded to the extended position. The tracks are sufficiently elastic to accommodate the movement of the one wheel from the extended position to a retracted position. The arms are pushed into the retracted position when the vehicle is pushed into a combined remote control unit and storage case.
