"Remote-controlled" refers to devices that can be operated from a distance using a remote control. This technology allows users to manage various functions without needing to be physically close to the device. Common examples include remote-controlled cars, drones, and television sets. These devices typically use radio signals or infrared light to communicate with the remote control. When a button is pressed, a signal is sent to the device, instructing it to perform a specific action, such as moving forward or changing channels. This convenience has made remote-controlled devices popular in both entertainment and practical applications.
