Wireless Mesh Underground Rescue Robot for Post-Disaster Mine Emergency Response

Post-disaster underground mine rescue requires environmental perception and remote operation before personnel can enter hazardous areas. In this article, we describe the system-level integration of a tracked detection robot, a 1432–1442 MHz wireless Mesh link, three deployable relay beacons, a handheld terminal, and multi-parameter sensing. The radio modules use 0.5 W transmit power, a nominal 30 Mbps data rate, and vertically polarized 5 dBi omnidirectional antennas, while the analytical formulation links differential-drive commands, path-loss and link-quality estimates, and a consecutive-sample beacon deployment rule. Physical records from three mine rescue test facilities document manual motion, navigation interface operation, Mesh topology formation, environmental data display, and audio/video return. While these records establish prototype feasibility and functional-chain continuity, they do not provide retained quantitative RSSI, packet loss, latency, trajectory error, stopping distance, endurance, or repeated-trial statistics. Accordingly, the proposed models are presented as design and measurement frameworks rather than validated predictors or evidence of performance superiority.
