A toy includes a vehicle body having a front portion and a rear portion. A pair of rear wheels is coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion. A first electric motor is drivingly coupled with the at least one rear wheel. There is a pair of front wheels coupled with the front portion and located on the vehicle so as to at least partially support the front portion. An electrically operated steering actuator is mounted on the front portion and is drivingly coupled to the at least one front wheel to rotate the front wheels to steer the toy vehicle. When the vehicle is inverted, the sensor detects the orientation change and signals a microprocessor inside the vehicle, the microprocessor responds to the signal and changes the left/right motor control signal to the steering motor and the forward/backward motor control signal on the driving motor. |
