Safety of the personnel is the primary focus in underground coal mining industry. Underground communication is necessary to monitor underground environmental parameters such as temperature, humidity, toxic gas, metals etc. and take necessary actions accordingly to avoid any types of hazard. In this project, a robot based wireless monitoring and safety system for mines using wireless communication and android applications is proposed, which will acquire the data of environmental parameters of underground mine using different sensors and send the data to control room using camera. The whole system is placed on a robot(quadx) which is operated by remote or android application. Use of wireless robot reduces the human intervention in security system and improves the safety of the personnel.
