A toy consists of a base, a cap and a toy model. The base has stationary wheels and a movable wheel located on the bottom section thereof. The movable wheel may be driven through a gear set by battery power for moving the base around. The cap has a hollow casing located on the top section to house a motor that is driven by a battery for rotating the cap through another gear set. The base has an arched gear rack located on the top surface. By way of an elastic element and a lever to couple with the gear sets and arched gear rack, the cap may be moved to the left and right, and rotated positively and reversely to generate a wide variety of simulative motions.
