Introduction Radio control (often abbreviated to R/C or simply RC) is the use of radio signals to remotely control a device. The term is used frequently to refer to the control of model vehicles from a hand-held radio transmitter.

Industrial, military, and scientific research organizations make [traffic] use of radio-controlled vehicles as well.

A remote control vehicle is defined as any mobile device that is controlled by a means that does not restrict its motion with an origin external to the device.

This is often a radio control device, cable between control and vehicle, or an infrared controller. A remote control vehicle (Also called as RCV) differs from a robot in that the RCV is always controlled by a human and takes no positive action autonomously.

One of the key technologies which underpin this field is that of remote vehicle control. It is vital that a vehicle should be capable of proceeding accurately to a target area; maneuvering within that area to fulfill its mission and returning equally accurately and safely to base.

Recently, Sony Ericsson released a remote control car that could be controlled by any Bluetooth cell phone.

Radio is the most popular because it does not require the vehicle to be limited by the length of the cable or in a direct line of sight with the controller (as with the infrared set-up). Bluetooth is still too expensive and short range to be commercially viable.
