remotecontrolled

Remote-controlled is an adjective describing a device that is operated from a distance by a separate controller. A remote-controlled device contains a receiver that interprets signals from a transmitter and converts them into actions such as steering, propulsion, or actuation. The term is commonly hyphenated as remote-controlled; in some contexts it may appear as remote controlled or simply RC.

Technologies used in remote-controlled systems include infrared (IR) and radio frequency (RF) links. Infrared control requires line of sight and works over short ranges, while RF-based controls—often at 2.4 GHz or other bands, sometimes with spread-spectrum or frequency hopping—offer greater range and non-line-of-sight operation. Some devices use Bluetooth or Wi‑Fi for control or integration with smartphones and networks. Modern designs typically incorporate safety features such as fail-safes, encrypted signals, and telemetry feedback.

Applications of remote-controlled devices span toys (cars, boats, airplanes, helicopters), drones and unmanned vehicles, model railways, and various robotics platforms. In consumer electronics, remote control functions are used for operating media players, home automation devices, and assistive technologies. In industrial settings, remote control supports operations of machinery, robotics, and process equipment over wireless links or dedicated control networks.

Terminology and scope: RC is a common shorthand for radio-controlled systems. The broader field of teleoperation covers remote operation over longer distances or networks, sometimes via the internet or specialized interfaces.

Safety and regulation: RF remote controls are governed by regional radio-spectrum rules (for example, FCC in the United States, CE/RED in Europe). Toys and consumer devices may need safety certifications, battery standards, and compliance with applicable privacy and aviation regulations for airborne systems.
