How Radio-controlled Cars Work
Radio-controlled cars, just as their name suggests, are cars that are controlled by radio waves. The radio waves are sent from the remote which operates the car to the cars. The mechanism of action of radio-controlled cars is similar to that of other radio-controlled toys. Several components which are common to all remote-controlled toys control the mechanics of radio-controlled cars. This article explains the basic processes involved in the movement of a radio-controlled car, and how the different components that make up the car effect these processes.
Every radio-controlled car is made up of four essential components. The components of a radio-controlled car include the transmitter, the motors, the power source and the receiver. These components coordinated the actions of every radio-controlled car.
The transmitter of a radio-controlled car works by sending signals to another component of an RC car known as the receiver. Thus, the transmitter is the component of an RC car that sends the radio waves to the car. The transmitter of an RC car is an essential part, as, without it, signals cannot be sent to the car. The transmitter is thus the origin of the radio waves.
Remote-controlled and radio-controlled cars differ in the way their transmitters are built. Radio-controlled cars send signals without a wire connection, while remote-controlled cars need wire connection. The radio waves of different transmitters work at different frequencies. The most common frequencies are 27 and 49 MHz, although some RC cars work with frequencies of 72 and 75 MHz. Transmitters and the control of the car make up the handheld device that comes with most RC cars. The specific frequencies of RC cars ensure that the car picks up only the assigned frequency of the car.
The transmitters of RC cars are typically powered by a 9-volt battery. Some RC cars are powered by small internal combustion engines. The transmitters of RC cars may be single-controlled or full-controlled. The signals of single-function controller cars are differentiated in two ways, while the signals of full-function controllers are differentiated in about six ways according to different pulses.
Signals sent by the receiver are effected by the integrated circuit which controls the motors of the car. For full-function controllers, the signals sent to the IC determine the motor which is turned on and the action which the car takes.
The receiver is the component of the car to which the radio waves are sent. The signal sent by the transmitter is received by the antennae of the receiver. The receiver also has inductors and a component that oscillates at specific frequencies, the frequency of the transmitter.
The circuit board of an RC car is another of its basic components. The circuit board receives the electrical pulses and is the basic electrical component of RC cars.
Basically, this is how an RC car works. The transmitter sends the signals which are received by the receiver. The receiver interacts with the circuit board which translates the signals that drive the motors.
