A remote control Robots is defined as any Robots that is remotely 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 Robots, or an infrared controller. A remote control Robots differs from a simple robot, is always controlled by a human and takes no positive action autonomously.
Remote control Robots have various scientific uses including hazardous environments, working in the Deep Ocean, and space exploration. It is used by police to detect bombs, or some chemicals,etc. It detects chemicals with its high-power sensors. The majority of the probes to the other planets in our solar system have been remote control Robots, although some of the more recent ones were partially autonomous. The sophistication of these devices has fueled greater debate on the need for manned spaceflight and exploration.
Remote control Robots are used in law enforcement and military engagements for some of the same reasons. The exposure to hazards are mitigated to the person who operates the Robots from a location of relative safety. Remote controlled Robots are used by many police department bomb-squads to defuse or detonate explosives.
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 Robots 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). These also include remote controlled helicopters.
