In this project, we present the controlling of a Robot using BLUETOOTH technique. The robot is controlled by a mobile accelerometer through Android Application. In the course of the Android Application, User can use various commands like forwarding, backward, stop, left, right. These commands are sent from the Android mobile to the Bluetooth receiver. This project is built on the 8051 microcontrollers; this project is housed on a robot base, which moves forward, When the data is received from the Bluetooth to the microcontroller, according to the signal the robot moves that direction. L293D is used to drive the motors. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of the secondary 230/12V step-down transformer.
