Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, etc. Here, It is used for the automatic battery replacement of home surveillance robot. The proposed system is composed of the surveillance robot and the docking section for the automatic battery replacement of the surveillance robot. The palm-sized surveillance robot communicates with the general wireless home router through Wi-Fi. It communicates with the docking section through Zigbee and serves as a mobile sensor network gateway. The time duration capability is a critical function for the surveillance robots and it is relied on the power supply. The charging duration of the battery mounted in the robot is an important issue. Battery replacement of the surveillance robot is the best solution to increase the long term activity of robots. The robot can return to the docking section for battery replacement when the battery is too low. So the robot need not to be turned off for long duration of time while replacing the battery. MATLAB is used to implement this battery replacement process of surveillance robot.
