TXR Robotics demonstrates wildfire robot that builds firebreaks on steep terrain

Building firebreaks — rapidly clearing vegetation to stop flames from spreading — is considered one of the most critical tools in wildfire response.

Early action of this kind can determine the scale of damage a wildfire causes. But in mountainous and steeply sloped terrain, equipment is hard to deploy and workers are often sent in directly, creating serious safety risks.

A robotic solution to these challenges was recently put on display. A wildfire-response robot designed to build firebreaks was demonstrated Thursday at a forest site in Yonghyeon-dong, Uijeongbu.

The robot unveiled that day by TXR Robotics is equipped with a high-output rotary cutter running at 2,500 RPM, capable of clearing trees up to 100 millimeters in diameter to carve out firebreaks. Powered by a 48-horsepower diesel engine, it can operate for up to four hours continuously.

"With a tracked, low-center-of-gravity design and dual rubber tracks, the robot can travel and work in rugged terrain including mountain slopes of up to 55 degrees and valley floors," the company said. "Remote control of up to 150 meters allows it to operate in hazardous areas inaccessible to personnel."

The company added that beyond rough terrain, the robot can also be deployed at national and provincial parks, traditional Buddhist temples and military facilities in mountainous areas. The demonstration showcased the robot performing unmanned firebreak construction in such conditions.

Eom In-seop, chief executive of TXR Robotics, said the company plans to expand its robot business into public disaster-response sectors, including local governments and forestry agencies.
