The document describes a proposed coal mining safety robot. The robot would detect toxic gases, monitor temperature and humidity, detect and extinguish fires. Its objectives are to improve worker safety in hazardous coal mine conditions. It would contain components like sensors, an Arduino, motors and would use technologies like Bluetooth, Zigbee and digital modulation to function remotely. While improving safety, its range and mobility are limited but it could enable capabilities like exploration, fire detection and rescue operations. In conclusion, as coal mines become more automated, safety monitoring robots will play a greater role in inspection.

8. MODULATION USED IN OUR
PROJECT
Digital Modulation Techniques such
as frequency-shift keying (FSK) or phase-
shift keying (PSK) are commonly used
modulation techniques in industrial
applications for signal transmission and
reception, including robotics.
• Uses Binary code tp transmit data and
can provide high data rates and low
error rates.

9. ADVANTAGES
• Improved security.
• Increased efficiency.
• Increased accuracy
• Remote operation
• Data collection

10. LIMITATIONS
• Sensor can be sense in limited range.
• It can control the movement of vehicle upto a certain range.
• They have limited mobility.
• Dependence on communication infrastructure.

11. POTENTIAL FEATURES
• Exploration and Mapping in Mines.
• Robots can be equipped with sensors to detect gases.
• Fire Detection and Suppression.
• Rescue Operations.
• Hazardous Material Handling.

12. CONCLUSION
As national coal mines become intelligent and the
unmanned strategy is gradually advanced, the coal mine safety
monitoring robot will play a greater role in the field of coal mine
safety inspection, and the technical development of coal mine
safety monitoring robot will change quickly.
