Abstract
This literature review examines research related to robotic exploration, environmental monitoring, hazard detection, navigation and safety inspection in underground and other confined environments. The reviewed studies cover ground robots, aerial robots, multimodal systems, sensor fusion, gas monitoring, mapping, localization, autonomous exploration and robotic inspection. The findings provide a technical background for the development of a low-cost cave hazard detection robot using ultrasonic distance sensing, air-quality monitoring and temperature-humidity sensing. The difficulties of constrained and irregular environments such as poor sight, uneven terrain, poor communication, unpredictable weather conditions, and the presence of potentially dangerous gases are given special emphasis. The evaluation also considers how autonomous navigation and sensor integration might enhance operational safety, situational awareness, and obstacle avoidance during exploration. The usefulness of integrating environmental sensors with distance measuring and control mechanisms is demonstrated by current robotic systems; yet many sophisticated solutions need expensive implementation, intricate hardware layouts, or computationally demanding algorithms. These drawbacks emphasize the necessity for a flexible and reasonably priced robotic platform that can be used for initial cave investigation and danger detection. The literature study demonstrates the value of incorporating temperature-humidity monitoring, air quality testing, and ultrasonic sensing into a small mobile robot. Such a device can facilitate distant monitoring, offer early warning signs of environmental dangers, and lessen the necessity of direct human exposure to potentially dangerous confined places.
