Toy vehicle programmed to follow a manually drawn path

摘要

A toy vehicle is configured for itinerant maneuvers and is programmed by manually drawing a path on an exposed surface of a mechanical touch screen assembly on the vehicle. A microprocessor, coupled with the touch screen assembly, reads the manually drawn path and controls movement of the vehicle to follow the manually drawn path. In one embodiment, the drawn path is erased to enter a new path by pivoting the first sheet of the assembly away from the second sheet and, in another embodiment, by separating the first and second sheets by sliding a horizontal plate between the sheets. A sensor on the vehicle detects the presence of a stylus in a holder. The microprocessor responds to the presence to initiate the itinerant movement and/or activate a visual indicator or an audio generator or both in the toy vehicle.
