The large, remote-controlled car — someplace between a tractor trailer, a tank and a Zamboni in look — slowly rolled throughout the dry, brittle grass rising between the tangle of freeways making up the 101 and 23 interchange in Thousand Oaks.
Contained in the beast, hearth churned. And because it rolled over the land, that fireside incinerated any brush it encountered, leaving solely a skinny smoke cloud billowing from the highest of the machine, some flashes of orange and crimson from behind its steel skirt and, in its wake, a desolate, smoldering black line.
BurnBot isn’t the quickest method to rid a panorama of dangerously flammable vegetation (it tops out at round 0.5 mph) however it will probably do one thing that conventional vegetation administration methods can’t: with nearly surgical precision, it will probably kill the flammable brush sitting inside ft of houses and highways on even the most well liked and driest days and with just about no security dangers or disruptions to every day life.
On a latest summer season afternoon, as wildland firefighters maneuvered the machine and mopped up the charred earth on a stretch of freeway about 30 miles west of Los Angeles on the 101, a who’s who of SoCal’s wildfire management appeared on — from the California Division of Forestry and Fireplace Safety, native hearth departments, Caltrans, the U.S. forest and park providers, Southern California Edison and state Legislature. The candy smoky odor of wildland hearth permeated the recent noon air. The onlookers quietly took notes.
“We have to do everything we can to try to figure out ways to lower our wildfire risk in a psychologically friendly way — we don’t want to just turn this beautiful environment into concrete,” state Sen. Benjamin Allen (D-Santa Monica) instructed the group whereas standing atop BurnBot’s steel skirt. “We’re looking for innovative solutions, and I’m just glad to see this kind of work.”

As people ignite fires with rising frequency in Southern California — and proceed to construct deeper into fire-prone areas — wildfire policymakers and scientists are racing to higher perceive tips on how to handle the disaster.
Personal buyers are throwing thousands and thousands of {dollars} on the downside, and consequently, a slew of entrepreneurs and former firefighters are attempting their hand at growing high-tech options.
Few of the rising applied sciences — together with BurnBot — have confronted rigorous scientific scrutiny but: Fireplace researchers in Southern California nonetheless haven’t collected sufficient information to decide on which broad methods are best, not to mention which corporations are greatest at carrying them out.
However, BurnBot has caught the eyes of the departments and organizations spearheading wildfire mitigation in California.
“We’re always looking at what new technologies there might be that we can utilize to enhance our vegetation management program,” mentioned Andrew Dowd, public info officer with the Ventura County Fireplace Division, which despatched a small crew to take a look at the bot.

BurnBot is the brainchild of laptop scientist Anukool Lakhina and physicist Waleed Haddad.
After the 2020 Northern California fires, the 2 put their heads collectively to develop a know-how answer for the state’s disaster. They settled on basically a “Roomba for the forest” (as one onlooker on the August demonstration put it).
Haddad constructed a prototype of BurnBot within the kitchen of Lakhina’s San Francisco house to persuade hearth scientists and buyers that the thought may really work. Its first meal: Lakhina’s yard.
As we speak, the corporate has constructed 5 full-size BurnBots — known as the RX, shorthand for the “prescribed” in “prescribed burn.”
Whereas the tech was developed and primarily examined in Northern California, Lakhina thinks it will probably assist Southern California tackle its two distinctive wildfire risk-reduction targets: decrease the variety of ignitions and create strategic gasoline breaks to gradual hearth and provides firefighters entry to the area’s fire-prone wildlands.
BurnBot hopes to thwart human–began fires by eradicating flammable grasses alongside widespread ignition factors, like roadways and energy strains. Automobiles and electrical tools have traditionally brought about roughly 2% of fires within the area. Arson, unsupervised children and varied agriculture, building and landscaping tools have been answerable for the lion’s share; nonetheless, even these are far more widespread alongside roadways and close to developments, the place BurnBot hopes to function.
At the moment, companies similar to Caltrans usually depend on routine mowing to combat the flammable grasses alongside transportation corridors and in populated areas. However mowing doesn’t fully destroy the grasses; it simply provides them a haircut. Their seeds keep hidden underground, and the grasses develop again shortly.
Herbicides, one other widespread approach for managing invasive grasses, are sometimes costly to buy and might go away poisonous chemical compounds within the atmosphere after therapy.
In the meantime, prescribed burns can cowl a number of floor and, in the event that they burn scorching sufficient, can destroy invasive seeds. Nevertheless, conventional prescribed burns can require highway closures for security causes, and hearth crews sometimes solely carry out them in cooler, wetter circumstances to restrict the danger of a robust, runaway hearth.
BurnBot RX, nonetheless, can safely run any day, Lakhina mentioned. Its most up-to-date demo was Aug. 27, throughout peak hearth season in sweltering 90-degree climate. The one visitors management was a couple of cones positioned alongside the freeway’s shoulder. No highway closures; no blocked lanes creating congestion.
The bot’s handlers also can finely management the warmth of the burn, making certain the seeds of invasive vegetation hiding the soil get scorched too.

Whereas the analysis evaluating BurnBot’s success is proscribed proper now, Lakhina mentioned his firm is working with Stanford researchers to judge how land recovers after a go to from BurnBot. To this point, they’ve seen anecdotal proof that after a burn, fire-resilient native species usually return as an alternative of invasive grasses.
The corporate plans to maintain its 5 at present functioning BurnBot RXs within the household, the place their skilled technicians and wildland firefighters will use them to finish wildfire danger discount work throughout the state. Within the coming years, they plan to aggressively develop the scale of their operation. Lakhina mentioned the corporate plans to construct 15 subsequent yr and 50 the yr after.
“Unlike other kinds of disasters, we have a lot of agency here: … Take out the fuels, reduce the risk,” Lakhina mentioned. “California has wildfires, but California also has innovators. Shame on us if we can’t sort our way out of this.”
