![]() In this project we used DTMF decoder, Microcontroller and motor drive integrated circuit.īLOCK DIAGRAM of Wireless controlled robotįig abpve shows the block diagram of microcontroller based mobile phone operated land rover and the important components are this rover are DTMF decoder, Microcontroller and integrated circuit motor driver. Dual tone multiple frequency mean when we press any button at that time two frequencies are generated one is low frequency and other is high frequency. This tone is called Dual Tone Multiple Frequency (DTMF). When the circuit have connected then press any button of remote location side mobile, the same tone we can hear to the receiver side mobile. When we makes a call from the mobile which is at remote location, then the mobile at the receiver side connect the circuit. In this Wireless controlled robot two mobile is used, one mobile is used as a remote control and another is used as a receiver which is attached to the robot through hands free. This provide the feature to operate the robot from remote locations. The main objective of this project is to build a mobile phone link between a transmitter and an unintelligent robot. ![]() ![]() Wireless controlled robot using mobile phone It provides the robust control, large working range and easy to use at everywhere. The mobile phone robotic control can overcome these limitations. ![]() The RF circuits which have the drawbacks limited frequency range, limited working range, limited control and cannot use at remote areas. This is one type of robot is controlled by a cell phone, conventionally wireless controlled robot using RF circuit. ![]()
