Radioohjauksissa, often translated as radio control or RC, refers to the technology and practice of controlling a device from a distance using radio waves. This encompasses a wide range of applications, from hobbyist model aircraft, cars, and boats to sophisticated industrial and military equipment. The fundamental principle involves a transmitter that encodes commands into radio signals, which are then sent to a receiver on the controlled device. The receiver decodes these signals and translates them into actions, such as moving a steering mechanism or activating a motor.

The complexity of radio control systems can vary significantly. Simple RC toys might use basic on-off signals for movement and direction. More advanced systems employ proportional control, allowing for nuanced adjustments in speed, steering angle, or other parameters, much like a real-world counterpart. The frequency bands used for radio control are regulated to prevent interference between different devices. Common bands include 27 MHz, 40 MHz, and 2.4 GHz, with the latter becoming increasingly prevalent due to its superior resistance to interference and ability to support multiple simultaneous users.

Beyond hobby applications, radio control is vital in sectors like robotics, where it enables remote operation of robots in hazardous environments. It is also used in surveying, construction, and even in some aspects of aviation and maritime operations for remote piloting or control of specific functions. The development of digital radio control technology has further enhanced precision, reliability, and the number of functions that can be controlled simultaneously.
