Bluetooth is a wireless module which transfers data two Bluetooth devices. This module enables you to transmit & receive wireless data in serial format. It is an advanced technology which can is widely used now-a-days in mobile data sharing and within network communications like modem to printer, etc. Allowing transparent two way data communication. In our project we can simply use it for transmitting wireless serial data to establish connection between MCU or embedded project and PC. Our project is designed for surveillanceapplications, for which we are using a wireless camera and a Bluetooth modem for navigating the robot. Here we control the robot through PC hyper terminal or .net c# application. Bluetooth modem is connected to micro controller serially with 9600 baud rate. The range of Bluetooth modem is 10 meters with frequency 2.4 GHz. Blue tooth Transmit power is 4dBm and sensitivity is 84 dBm. Here in our project Bluetooth modem acts as receiver and an android application acts as transmitter which is paired to the Bluetooth module. In this way we can control the robot
