Abstract

To address the issues of high cost and large size of mainstream firefighting robots, which make them difficult to adapt to small fires and confined-space firefighting needs, this paper designs an intelligent firefighting robot with an STM32 microcontroller as its control core. The robot integrates multiple functional modules, including path tracking, obstacle avoidance, flame detection, and fire extinguishing apparatus. By employing a modular and top-down software design approach, the program enables functions such as path tracking with obstacle avoidance, fire source recognition, automatic fire extinguishing, and remote-controlled fire extinguishing. Experimental results indicate that the robot can extinguish fires within 50 s, 70 s, and 90 s in scenarios with 4, 8, and 12 fire sources, respectively. Moreover, the firefighting success rate increases with the number of trajectory laps: the number of fires extinguished after two laps increases by at least 12.5% compared with one lap, and that after three laps increases by at least 25%. This demonstrates that the robot can efficiently meet the firefighting needs of small-scale fire scenarios.
