Conventionally, wireless-controlled robots use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for robotics control can overcome these limitations. It provides the advantages of robust control, working range as larger as the coverage area of the service provider (range all over the world), no interference with other controllers. "DTMF Controlled Wireless Robotic Car" is capable of receiving a set of command (instructions) in the form of DTMF tones and performs the necessary actions such as left, right, back, forward etc. Here DTMF stands for "Dual tone multiple frequency". We will be using a dedicated modem/mobile at the receiver module i.e. with the robot itself and send the commands using DTMF tones as per the required actions. We can control robotic car by C-code software through DTMF tones generator chip. It is also called "Programmable Robotic Car". Because recording DTMF tones and play back will be able to control robotic car automatically.
