Last year’s record heat wave worsened drought and dry conditions across the globe, a particularly calamitous situation for California, which has seen 13 of the state’s 20 most destructive wildfires in history break out since 2017.
In South San Francisco, a small startup is working on a high-tech approach to wildfire prevention.
Anukool Lakhina and Waleed “Lee” Haddad founded BurnBot in 2022 to develop robotics and remote-controlled vehicles that can munch up and burn away invasive plants or other dry vegetation that can fuel fires if left fallow.
BurnBot has just raised a $20 million funding round led by climate-focused ReGen Ventures, for expansion, hiring, and to develop new machines that can traverse steeper hills and get into tighter spaces.
Before BurnBot, firefighters and land owners had to use expensive, time-consuming and more dangerous options like grazing away the vegetation (typically with goats), burning it, applying herbicides or removing vegetation mechanically with a mix of equipment and manual labor.
“The sort of traditional way to do a prescribed burn is with drip torches, and that requires a large number of people,” said Lakhina, BurnBot’s CEO. “A drip torch is like a diesel watering can. You go around, you drop diesel, then ignite it.”
Burnbot’s current model, the RX, is a remote-operated vehicle that looks a cross between an oversized Zamboni and a steel cooking range with a set of fire extinguishers strapped to its back. Like other agricultural and construction equipment, the RX rolls forward on tank-like tracks and wheels, which enable it to maneuver through rough fields.
Within the chambers of the RX are several rows of torches that emit blue flames, and adjust the heat levels precisely to zap away unwanted vegetation or other fuels on the ground below. The chambers of the BurnBot RX also trap and torch away the smoke that comes from burning vegetation, so it doesn’t pollute the air in surrounding communities. When the torching is done, the RX sprays water repeatedly to extinguish any remaining embers.

Lakhina said BurnBot’s systems can be put to use where traditional controlled burns won’t work. For example, drip torch burns produce a good deal of smoke, which is conductive enough it would interfere with the proper functioning of power lines or high-voltage equipment. BurnBot’s machines can be used even under power lines.
The company is aiming to make every person who works in fire prevention 10 times more effective than they were with old methods, Lakhina said.
Haddad, BurnBot’s chief technology officer, noted that land isn’t always ready to “receive fire” in a prescribed burn. So the company has programmed equipment, which it procures from another supplier, to roll ahead of the RX to crunch up the vegetation in an area of concern before it’s ready for torching.
BurnBot plans to conduct a prescribed burn this Friday in San Diego, a project for CalTrans, the state’s transportation agency. It also plans for another burn for Pacific Gas & Electric, the state’s major utility, in June.
PG&E spends upward of $1 billion on “vegetation management” each year. Kevin Johnson, who leads the company’s Wildfire Resilience Partnerships, said PG&E is always “looking for opportunities to do this work safer, faster, cheaper and to be more environmentally friendly.”
BurnBot has already completed one demonstration of its controlled burn machine underneath PG&E transmission lines.
Brice Muenzer, a battalion chief with CalFire in Monterey, California, said massive fires in the state and throughout the U.S. over the past decade have been partly caused and certainly exacerbated by overzealous elimination of smaller fires, including ritual fires from indigenous communities.
“We removed fire from the ecosystem for the last 150 years and are living through that reality now,” the chief said.
CalFire has worked with BurnBot personnel, machines and additional drones overhead, to create what’s known as a control line in the field in at least one location. Muenzer says the group hopes to do more with the startup.
Creating a control line, or blacklining the land, involves firefighters strategically burning areas when the weather is calm and where flames can be controlled to create scars that will block other fires from jumping in and reaching areas with lots of new material to burn.

BurnBot aims to eventually expand its operations beyond California, with offices and fleets of its machines wherever vegetation management is needed and wildfire risk is highest.
“There are 50 million acres that the U.S. Forest Service has said need treatment every year and that’s just forest land,” said Lakhina. In the U.S. there are 237 million acres that need treatment overall. And grazing can cost $1,000 an acre.”
Childrens’ health is at stake along with property and healthy forests, Lakhina added. According to the Harvard School of Public Health, wildfire smoke can be more toxic than air pollution from other sources, leading to more emergency room visits, especially for children who are exposed.
Because BurnBot offers greater precision than grazing, herbicides and mechanical removal, its systems should prove ecologically more beneficial as well, Haddad said. The BurnBot RX is able to help prevent the spread of seeds from invasive species, for example, without causing any of those species to develop resistance to an herbicide.
ReGen was joined in BurnBot’s funding round by investors including AmFam Ventures, which is the venture arm of an insurance company, Toyota Ventures, and earlier backers including robotics fund Pathbreaker, Convective Capital and Chris Sacca’s Lowercarbon Capital.

Driverless WeRide robotaxis for Uber.

Uber on Wednesday rolled out fully driverless rides in its fourth market, launching the service in Abu Dhabi in partnership WeRide, a Chinese autonomous vehicle company.
The ride-hailing company said the launch in the United Arab Emirates capital represents the first driverless robotaxi service in the Middle East. In the U.S., Uber already offers robotaxi services in Austin, Phoenix and Atlanta through Alphabet’s Waymo.
Riders in Abu Dhabi can book a WeRide robotaxi when requesting an UberX or Uber Comfort ride, the ride-hailing company said.
WeRide, which is listed on the Nasdaq, formed its partnership with Uber in September 2024 and began offering autonomous rides with an operator on board in Abu Dhabi last December. Uber and WeRide also debuted robotaxi rides with a safety operator on board in Riyadh, Saudia Arabia, in October. In May, Uber said it plans to roll out the WeRide service to 15 more cities, including in Europe, over the next five years.
In recent years, Uber has bet big on autonomous vehicle technology through partnerships.
Uber started offering a robotaxi service in Austin and Atlanta earlier this year, and in Phoenix in late 2023. In July, the company landed a six-year robotaxi deal with electric vehicle maker Lucid and AV startup Nuro.
WeRide, meanwhile, has launched full driverless robotaxi services in China’s Beijing and Guangzhou, according to its website.
Uber has not said how it splits revenue from robotaxi rides with its partners.
Competitors have also readily adopted the technology, with Lyft announcing a deal with Waymo in September to launch robotaxis in Nashville next year.
Uber said the driverless vehicles in Abu Dhabi will operate in certain areas of Yas Island. Riders can boost their chance of a robotaxi drive by selecting the autonomous option. On-board support is available during the ride through the app and an in-vehicle tablet.

Amazon is facing a federal probe after one of its delivery drones downed an internet cable in central Texas last week.
The probe comes as Amazon vies to expand drone deliveries to more pockets of the U.S., more than a decade after it first conceived the aerial distribution program, and faces stiffer competition from Walmart, which has also begun drone deliveries.
The incident occurred on Nov. 18 around 12:45 p.m. Central in Waco, Texas. After dropping off a package, one of Amazon’s MK30 drones was ascending out of a customer’s yard when one of its six propellers got tangled in a nearby internet cable, according to a video of the incident viewed and verified by CNBC.
The video shows the Amazon drone shearing the wire line. The drone’s motor then appeared to shut off and the aircraft landed itself, with its propellers windmilling slightly on the way down, the video shows. The drone appeared to remain in tact beyond some damage to one of its propellers.
The Federal Aviation Administration is investigating the incident, a spokesperson confirmed. The National Transportation Safety Board said the agency is aware of the incident but has not opened a probe into the matter.
Amazon confirmed the incident to CNBC, saying that after clipping the internet cable, the drone performed a “safe contingent landing,” referring to the process that allows its drones to land safely in unexpected conditions.
“There were no injuries or widespread internet service outages. We’ve paid for the cable line’s repair for the customer and have apologized for the inconvenience this caused them,” an Amazon spokesperson told CNBC, noting that the drone had completed its package delivery.
The incident comes after federal investigators last month opened a separate probe into a crash involving two of Amazon’s Prime Air drones in Arizona. The two aircrafts collided with a construction crane in Tolleson, a city west of Phoenix, prompting Amazon to temporarily halt drone deliveries in the area.
For over a decade, Amazon has been working to realize founder Jeff Bezos’ vision of drones whizzing toothpaste, books and other goods to customers’ doorsteps in 30 minutes or less. The company began drone deliveries in 2022 in College Station, Texas, and Lockeford, California.
But progress has been slowed by a mix of regulatory hurdles, missed deadlines and layoffs in 2023 that coincided with broader cost-cutting efforts by Amazon CEO Andy Jassy.
The company has previously said its goal is to deliver 500 million packages by drone per year by the end of the decade.
The hexacopter-shaped MK30, the latest generation of Amazon’s Prime Air drone, is meant to be quieter, smaller and lighter than previous versions.
Amazon says the drones are equipped with a sense-and-avoid system that enables them to “detect and stay away from obstacles in the air and on the ground.” The company recommends that customers maintain “about 10 feet of open space” on their property so drones can complete deliveries
The company began drone deliveries in Waco earlier this month for customers within a certain radius of its same-day delivery site who order eligible items weighing 5 pounds or less. The drone deliveries are supposed to drop packages off in under an hour.
Amazon has brought other locations online in recent months, including Kansas City, Missouri, Pontiac, Michigan, San Antonio, Texas, and Ruskin, Florida. Amazon has also announced plans to expand drone deliveries to Richardson, Texas.
Walmart began offering drone deliveries in 2021, and currently partners with Alphabet’s Wing and venture-backed startup Zipline to make drone deliveries in a number of states, including in Texas.
