TERRA ROVER: ENSURING SAFETY THROUGH ROBOTIC EXPLORATIONS

Abstract: Coal mines are prone to dangerous conditions such as gas leaks, structural failures, water flooding, and lack of proper communication during emergencies. This paper presents "Terra Rover," a compact, semi-autonomous six-wheel rover system built specifically for underground coal mine safety and rescue operations. It is designed to detect hazardous environments using an array of sensors (gas, water, temperature, ultrasonic crack detection), mark unsafe zones, and transmit live data to rescue teams. The rover is capable of navigating rough terrains with a custom mechanical suspension and can deliver rescue kits while maintaining real-time communication. Our system uses Arduino Mega and Esp32, integrated with wireless transmission and cloud logging. The rover also includes a fallback system to transmit last-known coordinates in case of destruction. The result is a robust, field-deployable, affordable platform for early hazard detection and safety support in coal mining zone
