Working Mechanism of Remote Control Cars – Information guide

Ever wondered what science and technology go behind the functioning of a remote control car? The simple-looking toy runs on a fundamental principle of radio frequencies being sent to the car, and hence it’s also called Radio Controlled Car. A lot goes behind the proper functioning of a Remote control car, and we are about to find that out in this article.

To briefly talk about remote control cars, they have been around since the 1970s and gained popularity across the globe in both children and adults. There are often racing competitions in which numerous car owners participate with their highly advanced models and variety.

It is called remote-controlled, as it can be controlled from a distance remotely through radio frequencies. Let us find out how do remote control cars work.

Parts Involved Functioning A Remote-Controlled Car

There are various models and types of remote control toys, amongst which the most popular ones are Remote control cars, trucks, airplanes, sailboats, etc. Every toy has the same four parts installed, which help it to send and receive signals.

1 – Transmitter
The transmitter is nothing but the remote that you use to control your toy from a distance. It’s called a transmitter because it sends a signal to the toys for it to run. Every little movement on the remote affects the functioning of your car.

2 – Receiver
The signals transmitted from the remote are being received in the toy cars with the help of a micro-chip circuit and an antenna, both of which are installed in the car. Once the signals are received, the motor gets activated and then runs as per the signals.

3 – Power Source
The power source is the most important as it fires up the entire system and enables smooth operation. In most cars, the usual power source is the batteries, but in a few models, gas is also a power source.

4 – Motor
The motor is the core structure, which, when started by the power system is responsible for the movement of all the car parts. It has a mechanism that allows the car to carry out essential functions like acceleration, wheel movement, steering, and braking.

Working Mechanism

As already mentioned above, the remote control cars work on radio signals. And how do remote control cars work is based on the following-

Step 1
Firstly, the transmitter or the remote needs to be powered on. And in most cases, a 9-volt battery is used. The car then has to be powered up, and it can be either manual switching on the remotely powered up. After it is powered on, the remote transmits a series of electrical impulses for a specific action. These signals are in the form of radio waves. The range of radio frequency in cars is usually 27 MHz or 49 MHz.

Step 2
Every car has a built-in receiver or antenna to catch the signals being transmitted. Once the signals are received for a specific action, the motors get activated accordingly. The power system fires up the motor and all other working parts of the car. The sequence of received signals makes the cars move accordingly.

Step 3
The remote control cars have several integrated circuit board which encodes and decodes the signals received and then indicated the motors to function. The receiver gets a continuous series of electrical pulses, and the circuits break down the functions individually. The basic controls involved are forward, backward, left, and right. But for each function, there is a different electrical impulse involved. For instance-

Forward Movement – 16 pulses

Reverse Movement – 40 pulses

Forward Left And Right – 28 and 34 pulses, respectively.

Reverse Left And Right – 52 and 46 pulses, respectively.

There are other functions, too, like speed control and breaks.

Range of Remote signals

When you choose a remote control car, one of the most important factors to consider is what the maximum reach of the transmission signal is. Generally, this means the distance from which the user has to control the vehicle. Needless to say, the longer the range, the better it is for controlling the vehicle. The average distance between the car and the controller can be 150 to 300 feet while functioning on a 2.4 GHz frequency.

There are, however, a few deciding factors that enable the signals to reach.

Quality Of Controllers
The quality of the transmitter and the receiver integrated circuits determine the strength of the radio frequencies sent and received.

Obstruction
When you are participating in a professional race or competition, the more the open spaces are, the better are the chances of signals being received without being lost in the way.

Potential Hindrance
Again, when you are part of a competition, there will be other signals too from other cars, and other infra-red waves, in general, can cause the signal to be feeble.

FAQs
1 – What is the average speed of remote control cars?

It all depends on the power system’s quality, but the average speed is between 30 and 60 mph. A few high-end models used in professional races and competitions can go up to 100 mph.

2 – What is the average frequency usage of a remote control car?

Most remote control cars 2.45 GHz frequency and is called Speed Spectrum System. The basic remote control cars function on 27 MHz or 49 MHz, and advanced devices function on 72 MHz or 75 MHz.

Conclusion
All these sequential functioning goes behind the just movement of the remote control cars, which, according to us, is nothing but the advancement of science and technology. The markets are infiltrated with various toys with advanced mechanisms and functionalities, but every toy follows this basic principle. We hope you have gathered sufficient information on how do remote control cars work.
