1) The document describes the design of a rescue robot for use in coal mines. Coal mine environments can be dangerous due to toxic gases, high temperatures, fires, and structural collapses that threaten human lives during disasters. 2) The proposed rescue robot would be equipped with sensors to detect gases, temperatures, and transmit video to rescuers to assess conditions and locate trapped miners before entering. It aims to reduce loss of life by providing information to first responders. 3) The robot design incorporates a Raspberry Pi computer controlled remotely via an Android phone app. Sensors would transmit data on gas levels, heat, and other factors wirelessly to rescuers for safety planning in hazardous post-disaster zones
