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 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 with in 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.


The First Remote Control Vehicle I
Precision Guided Weapon:
This propeller-driven radio controlled boat, built by Nikola Tesla in 1898, is the original prototype of all modern-day uninhabited aerial vehicles in air, land or sea. Powered by lead-acid batteries and an electric drive motor, the vessel was designed to be maneuvered alongside a target using instructions received from a wireless remote-control transmitter. Once in position, a command would be sent to detonate an explosive charge contained within the boats forward compartment. The weapon’s guidance system incorporated a secure communications link between the pilot’s controller and the surface-running torpedo in an effort to assure that control could be maintained even in the presence of electronic countermeasures. To learn more about Tesla’s system for secure wireless communications and his pioneering implementation of the electronic logic-gate circuit read ‘Nikola Tesla – Guided Weapons & Computer Technology’, Tesla Presents Series Part 3, with commentary by Leland Anderson.

Use of Remote Controlled Vehicles during World War II:
During World War II in the European Theater the U.S. Air Force experimented with three basic forms radio control guided weapons. In each case, the weapon would be directed to its target by a crew member on a control plane. The first weapon was essentially a standard bomb fitted with steering controls. The next evolution involved the fitting of a bomb to a glider airframe, one version, the GB-4 having a TV camera to assist the controller with targeting. The third class of guided weapon was the remote controlled B-17.

It’s known that Germany deployed a number of more advanced guided strike weapons that saw combat before either the V-1 or V-2. They were the radio-controlled Herschel’s Hs 293A and Ruhrstahl’s SD 1400X, known as ‘Fritz X’, both air-launched, primarily against ships at sea.
