This paper proposes a novel method to rescue humans trapped after an earthquake. It revolves around constructing an autonomous robot that can navigate and map the destroyed terrain and also locate any humans that are alive in that terrain. The navigation of the robot is done with the help of the on-board ultra-sonic sensor and is localized using Velocity Motion Model . The trapped humans are located through an on-board PIR sensor. The ultra-sonic sensors and the PIR sensors are connected to the Arduino UNO board and are interfaced with a Raspberry Pi b+ micro controller through serial USBcommunication. The algorithm for navigation of the robot and mapping the unknown terrain is done using Velocity Motion Model, which will be run in the Raspberry Pi after the robot has finished moving through the terrain. On the whole, this paper illustrates how robotics can be used for humanitarian purposes and also provides a cheap alternative to the traditional means of human body detection. © Research India Publications.
