A remote-control vehicle includes a controller that produces a pulse-width modulated (PWM) motor control signal and a forward/reverse motor control signal in response to a transmitted digital signal specifying one of a multiplicity of speed control states, each of which has a direction and a PWM duty cycle associated therewith. A MOSFET switch turns on and off in response to the PWM signal to control the flow of current between a battery and a motor to thereby control the speed of the motor. A relay, coupled between the battery and the motor, switches in response to the forward/reverse signal to change the direction of current flow through the motor to thereby control the direction of the motor.

Speed control system for a remote-control vehicle

A remote controlled, all-terrain toy vehicle has treads on both its left and right sides. Each tread extends over front and rear oversized, resilient wheels that allow the vehicle to travel on its top and bottom sides in forward and reverse. The vehicle is adapted for high performance on hard, flat surfaces, such as pavement, as a result of an elevated ridge on the tread that ensures low surface area contact with the ground and, which in turn, reduces ground resistance and increases the operating speed of the vehicle.
