In the current technological world, the technologies are evolving day by day. In the modern world, there is continuous development of skyscraper buildings & dwellings, which increases the risk of losing life by natural calamities and man-made disasters. During earthquakes, landslides, and building collapse, a lot of times, humans are trapped under debris and it becomes impossible to detect their presence by the rescue team. There are some cases where it is impossible for rescue teams to reach certain locations in affected areas. The Proposed system is a raspberry pi based human detection robot, which is used to detect live human beings trapped under debris in a affected environment. The robot navigates through the zigzag path and it is controlled by an android application. The set of sensors assembled to the raspberry pi are Microwave radar sensor, Ultrasonic sensor, Temperature sensor and Gas sensor. The Microwave radar sensor is also used to detect the human being behind the obstacle. The Temperature sensor is used to detect the temperature and Gas sensor is used for gas leakage respectively. And the camera module is used to analyze the current scenario.
