The project aims in designing robot for patrolling which moves towards the sound using sensors and raspberry pi.    Sound sensors are attached to the four sides of robot which is used to detect the sound from surroundings. DC motors along with l293d driver is used to moves and change the directions of robot. The Raspberry Pi is a low cost, credit-card sized computer that can be used in electronics projects. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. A DC motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by an alternator, generator or dynamo. The main controlling device of the project is raspberry pi processor .pi camera, GPS, Four sound sensors and DC motors along with L293d motor driver is interfaced to the raspberry pi. When the sound sensors detects the sound this data process to the raspberry pi then raspberry pi will start moves the robot towards the sound and then start the live streaming through pi camera and send this video along with location to the registered mail ID.
