Abstract: Now a day’s robots are use in various applications like industries, building, military etc. for surveillance and defensive purpose. The robot patrols a particular area by live video streaming operated by the controller. For defensive purpose, whenever the intruder is detected, the gun is triggered by the controller. Here USB camera and gun is varied at any angle controlled by the controller. The sensors are used here to sense smoke at surroundings, metal detector sensors used to determine the presence of metal nearby and heat sensor used if there is any fire in the surroundings. The sensing unit when detected causes LED light to turn ON. The motion of robot is controlled by the DC motor using Arduino Bluetooth technology by an Android App. For live video streaming the Raspberry pi is interfaced with the USB camera.
