Abstract: The paper proposes a new approach for detecting alive human beings in devastating environments using a low cost autonomous robot. The proposed alive human body detection system uses a specific set of sensors that gives information about the presence of an alive human body and a low quality camera to acquire a video of scene of the environment. Having detected an obstacle or alive human body, the set of sensors trigger the camera to show live scene. The video is then displayed on a PC or a laptop at base station and processed at MATLAB for further analysis. The alive human detection system proposed in this paper is highly reliable as it is using a set of sensors for detection. The data and information required to be acquired and processed for rescue operation are less. So, it is very cost effective and faster to be applied in real-time operating environment.
