In this paper, a new approach for finding human beings trapped under debris of earthquake, landslides or in some hazardous conditions viz nuclear radiation leak region, using a robot is proposed. The proposed robot monitors the area via CO2 (Carbon dioxide) sensor as CO2 increases there because of exhaled breath. The sensor triggers a buzzer as the CO2 level in its vicinity reaches a set threshold value to indicate the presence of a human being nearby. The robot also has an audio/video monitoring ability with the aid of a camera with an adjacent torch.
