Coal mine disaster is a common occurrence in mines after which rescue operations are immediately needed which is a risky one. The disaster results in increased level of harmful gases like CO and CO2 resulting in decreased O2 level and high temperature. Moreover the explosion might recur, making direct human intervention impossible inside the tunnel for rescue operation. To prevent human and material loss after mine explosion, a Robot is deployed inside the tunnel, which can travel inside the tunnel to sense gas contents, temperature and transmit the signals to the control room. The robot also has a wireless camera which will transmit live video signal to monitor the status inside the tunnel and to control the movement of the robot. The robot is a conveyor belt type robot enabling it to climb up the obstacles and move across debris. The ZigBee technology is used along with RF transceivers to carry out cheap and efficient wireless communication. With the help of this mobile robot, the loss due to coal mine disaster can be reduced and efficient rescue operation can be carried out.
