This project is developed for the users to operate a Robot through Bluetooth. The user can control all the movements like forward, reverse, left and right etc. The Bluetooth receiver is connected with the PC. A cell phone is used as Bluetooth transmitter.

First the transmitter and the receiver are synchronized. When the user presses a specific button of the cell phone, the Bluetooth receiver receives the signal and accordingly the software in the PC generates a digital signal and sends to the microcontroller through serial port.

The microcontroller controls the operation of the Robot through external electronic circuit like drivers and relays. The relay is used as a switch to operate the particular motor in the Robot. By this way the user can control any of the operations of the Robot.

The design and port programs are written in Visual Basic. The microcontroller program is written in assembly language
