“BurnBot is part of a nascent but fast-growing ‘fire tech’ sector that’s focused on preventing, detecting and suppressing wildfires. San Francisco-based Pano AI uses artificial intelligence-enabled cameras to spot fires earlier, while Santa Monica, California-based Rain makes autonomous helicopters to target blazes from above and France’s Shark Robotics builds firefighting robots for the frontlines.

BurnBot’s signature machine aims to make prescribed burns easier and safer. In addition to reducing manpower needs, the robot keeps combustion within its burning chamber, where propane torches and air blowers bring flame temperatures up to 1,000C (1,832F). Industrial-scale fans create upward airflow, trapping the flames and embers and reducing the risk of fire spreading outside.

That’s a key concern: Igniting vegetation is easier in dry weather, but fire services often prohibit it because of the risk a blaze will spin out of control. In 2022, escaped fire from two prescribed burns turned into the largest wildfire in New Mexico’s history.

BurnBot’s burns are also largely smoke-free. The intense heat, combined with a high-concentration stream of oxygen, destroys particulate matter.”
