How Do Remote Control Cars Work?
Understanding how RC cars work is very simple. The two important components of a remote controlled car are the radio transmitting remote and the radio signal receiving car. Both the components can be built using simple electronics. The radio remote works on the 29.9 Megahertz frequency. This article will explain how RC Cars operate and what they are made of.
The radio remote controller consists of the following parts:
- Trigger
- Integrated Chip
- Transmitter with antenna
- Battery slot
Trigger is the peripheral control unit. Pushing or pulling the trigger propels the RC car to move forward or backward. Electrical insulators attached to the triggers complete the integrated circuit when brought in contact with its electrical counterparts. When the circuit is closed at a particular juncture, radio signal is transmitted to the car to move according to the trigger movement.
The electrical pulses generated are of pulse type and is modulated by the Integrated circuit also the pulse modulator. These pulse signals are transmitted in just 2.1seconds to the RC Car receiver. The signal is transmitted to the integrated circuit in the RC car, which deciphers the signal and switches on the required motor. If the signal is 16 pulses then the RC Car moves forward, similarly if the signal is 16, 34, 28, 40 46 or 52 then the RC Car moves left forward, right forward, reverse, right reverse or left reverse respectively.
The antenna improves the working radius or the parameter of working of the RC car. The battery slot carries the battery, which is the source of power for the remote controller.
The RC Car consists of the following components:
- Antenna
- Circuit Board
- Battery slot
- Two Motors
The two motors do different work. The motor attached to the wheel in the front is responsible for the turning of the RC Car whereas the motor connected to the wheel in the back propels the car to motion forward or backward. Gears are fixed to the motor which connects the wheel.
The lower chassis and the shell top constitute the skeleton of the RC car. All the electronic and mechanical components are firmly held by the lower chassis. The shell top protects the components of the RC car and confers style to it.
Numerous diodes, capacitors and resistors institute the circuit board of the RC Car. The Circuit controls the motion of the motor and thereby the car. The radio receiver comprises of an antenna, inductors and a crystal that resonates at a particular frequency, which matches to that of the remote controller.
The battery slot carries the battery, which is the source of power for the RC car. Power flow to the electric motors is controlled by the integrated circuit. This simple but creative machine can entertain so much and has been a huge success in the toy market.
