Robots help to protect forests

Hubei has modernized its forestry management with the deployment of the province's first remote control robot for forest fire prevention, marking a leap toward integrating smart technology into ecological conservation efforts.

The cutting-edge equipment, put into service last November in Jingshan city, was developed specifically for challenging forestry scenarios and has demonstrated remarkable operational capabilities across difficult terrain. Its crawler-type transmission ensures reliable performance on steep slopes up to 60 degrees, while the 150-meter wireless control range allows safe operation from a considerable distance.

The machine's specialized cutting apparatus, constructed from high-strength steel, efficiently cuts trees measuring 15 to 20 centimeters in diameter and excels at rapid excavation of raw soil, making it particularly suitable for creating firebreaks, clearing paths for firefighters on foot and toppling burning trees.

"The robot operates continuously for eight hours and is remotely controlled by humans, greatly enhancing safety," said Chen Yong, fire prevention division director at Hubei Taizi Mountain forestry management bureau.

The technological innovation addresses critical challenges in remote and hazardous areas. Previously, workers had to dig firebreaks with traditional tools — a slow and hazardous process. Now, with robots taking over, efficiency has significantly improved, eliminating the need for personnel to risk their lives close to the flames.

"It triples operational efficiency and fundamentally enhances worker safety through remote operation," Chen said.

The Taizi Mountain area, characterized by extensive forests and complex topography, has struggled with limited access to remote zones and heightened risks during fire emergencies. Traditional manual methods often proved inadequate for rapid response requirements, particularly in establishing protective firebreaks.

The initial deployment includes two robots, with plans to distribute more units to frontline teams for broader application.

Chen said the province is conducting a training program in collaboration with the equipment manufacturer to ensure optimal utilization of the new equipment.

Beyond its primary fire prevention role, the robot supports various forestry management tasks, including land reclamation, clearing undergrowth and forest tending. This multi-functionality ensures year-round utilization, maximizing the return on technological investment.

The deployment comes as part of Hubei's broader initiative to upgrade its forest management infrastructure. The Wuhan Donghu High-Tech Development Zone has deployed 128 drone hangars, with an average of one unit per 2.5-kilometer radius, achieving comprehensive coverage without blind spots, Hubei Television reported.

Meanwhile, a multi-layered prevention and control system has been established, featuring satellite remote sensing for area-wide monitoring, ground video surveillance for close observation, and human patrols as a backup. Tao Huan, the drone project director at the zone's urban operation and management center, said the artificial intelligence algorithms for the forest fire prevention monitoring platform achieve an accuracy rate of approximately 85 percent in identification. "For alerts generated by the AI, our system is also equipped with professional personnel to conduct manual verification," Tao added.
