Cell phone operated robot

A robot is an automatically guided machine which is able to do tasks on its own, almost always due to electronically programmed instructions Radio control (often abbreviated to R/C or simply RC) is the use of radio signals to remotely control a device. This is often a radio control device, cable between control and vehicle, or an infrared controller. Our paper focus on operating robots by cell phone in order to simplify the control of robots. Methodology used is DTMF (Dual Tone Multi-Frequency). All over it 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.
