Kodama turns heavy gear used for forest thinning into autonomous or remotely operated machines. | Supply: Kodama Programs
The U.S. is at the moment dealing with a wildfire disaster. In 2022, wildfires burned over 7.5 million acres of land, in keeping with the National Centers for Environmental Information (NCEI). The Cybersecurity & Infrastructure Safety Company has estimated that wildfires have caused $81.6 billion in damage from 2017 to 2021, an almost tenfold enhance from 2012 to 2016. Kodama Programs Inc. is one firm providing a doable answer.
A number of elements have contributed to the present disaster. These embody a warming local weather and a rising variety of houses within the wildland-urban interface, in keeping with the U.S. Division of Agriculture (USDA) Forest Service. However you could be shocked to study that overgrown forests are additionally a key contributor, particularly within the Western U.S.
Traditionally, forests within the West had been a lot much less dense than they’re right now. Overstocked forests have resulted in better competitors for assets amongst vegetation in these areas, making them extra susceptible to drought and different stressors.
Scientific consensus additionally means that these overgrown forests are a key contributor to the present wildfire disaster. An abundance of smaller, typically weaker, bushes is able to burn.
Forestry is labor-intensive
Many authorities businesses and personal landowners at the moment are centered on eradicating materials from the forests to scale back potential gas hundreds. They’re turning to forest-thinning strategies that use machines to take away extra and unsafe vegetation. Their objectives are to enhance forest well being circumstances and hold wildfires from spreading uncontrolled.
Forest thinning isn’t a easy job. First, foresters are required for challenge planning and environmental evaluate. Subsequent, they create prescriptions for logging crews to chop choose bushes and different vegetation.
Then, a crew of staff hauls this materials out of the forest and hundreds it onto vehicles to move to varied locations like sawmills or processing amenities. A single challenge cycle might take months, and even years.
It’s a labor-intensive and bodily demanding job, and there aren’t sufficient organizations to fulfill state and federal remedy objectives. There are even fewer utilizing robotics.
Kodama Programs, a Sonora Calif.-based startup, is introducing applied sciences together with teleoperation and automation to enhance forest administration operations.
“Our mission is to revive forests for future generations, assist promote forest well being for the long run, and speed up the work that the state and federal businesses are calling for proper now,” James Sedlak, co-lead for operations and communications at Kodama, instructed The Robot Report.

Kodama works to forestall wildfires from burning uncontrolled
Whereas a number of corporations are utilizing robotics and synthetic intelligence to detect and suppress wildfires, Kodama is without doubt one of the few taking a extra proactive method by specializing in forest thinning.
“My background is in robotics and agriculture, and I’ve seen a whole lot of know-how adoption within the agriculture area,” mentioned Merritt Jenkins, co-founder and CEO of Kodama. “And after I began exploring forest administration, I didn’t see the identical price of know-how adoption.”
Forest thinning at scale requires varied kinds of heavy equipment. In a single method known as “whole-tree” thinning, a feller buncher cuts down bushes and bunches the logs collectively in a bundle. As soon as they’re bunched collectively, a skidder comes alongside and drags the bundle of logs from the reducing website to a touchdown.
On the touchdown, a processor delimbs and cuts the logs into merchantable lengths. After this, a loader makes use of a grapple to type, stack, and cargo the logs onto a truck for transportation. As soon as the bushes are reduce down, just a few issues might occur, in keeping with Jenkins.
“If you’re inside a cost-effective transport distance from a sawmill, and it’s stable, high quality materials, then you definitely take that materials to a sawmill,” he defined.
Nonetheless, if the supplies have imperfections, or the diameter of the tree is just too small, a sawmill received’t settle for them. If the corporate is working inside a cost-effective transport distance of a biomass energy plant, it could actually take this materials there.
However most of this small-diameter materials finally ends up being piled and burned. Because of this Kodama is developing a challenge to retailer this materials as carbon storage, mentioned Jenkins. The state of California recently estimated that roughly 84% of fabric is left within the woods.
“We’re growing what we name a ‘wooden vault,’ which is a technique of storing that materials underground for tons of of years in dry, anaerobic storage,” Jenkins mentioned. “With pile burning, virtually all of that carbon that’s saved within the biomass finally ends up going into the environment as CO2 emissions. As an alternative, you may lock that carbon away for tons of of years.”
Kodama mentioned its key differentiator can be aboveground. It’s growing remote-controlled and autonomous know-how for equipment within the woods to enhance the protection and productiveness of forest operations.
“Our purpose is to have semi-autonomous processes all through a forest-thinning operation,” Jenkins mentioned. “The preliminary focus is the skidder.”

Kodama Programs builds an autonomous skidder
“The skidder is usually touring alongside the identical trails many instances,” Jenkins mentioned. “That is a chance for automation as a result of you may map it after which comply with inside a map.”
The Kodama staff equips its semi-autonomous skidders with two major sorts of sensors: cameras and lidar. Because the skidder travels by means of the forest, it builds a 3D map of its environment.
“We’re introducing automation for these lower-hanging, tedious duties in order that we might release these very expert operators to do different high-value work on the challenge websites,” mentioned Sedlak.
“The skid path navigation is autonomous, and there are specific extra dexterous points of the operation the place we take over teleoperation,” Jenkins mentioned. “And that teleoperation continues to be native, so that you’re on the challenge website once you’re teleoperating.”
Kodama integrates its know-how with the machine’s controls. Something an operator can management from inside the cab, the corporate can management remotely, Jenkins mentioned.
Labor is a significant problem for this trade, he added. There aren’t a whole lot of younger folks wanting to enter the sphere, and working heavy equipment may be laborious on the physique, noticed Jenkins.
Kodama mentioned it’s additionally working to allow teleoperation from offsite places to get rid of lengthy commutes to websites and increase the operator workforce. Based on the staff, some staff drive as much as two hours to get to the work website day by day.
To this point, the Kodama staff has efficiently demonstrated its semi-autonomous skidder in industrial forest-thinning settings. Whereas the winter is a slower time for the corporate, significantly when it begins to snow within the Sierras, they’re gearing up for a busy spring.
Kodama mentioned its focus extends past the skidder, with plans to automate processing and loading operations.

Forest thinning shifting to the forefront of presidency coverage
Lately, authorities businesses have established initiatives aimed toward stopping catastrophic wildfires, and lots of of them embody forest-thinning objectives.
In 2020, California and the U.S. Forest Service established a shared long-term technique to handle forests and rangelands concentrating on 1 million acres of susceptible forest land per 12 months beginning in 2025.
The technique goals to scale back wildfire dangers, restore watersheds, defend habitat and organic variety, and assist the state meet its local weather targets. It cited a transition towards unnaturally dense forests as a danger issue.
Two years later, in January 2022, the Forest Service launched a 10-year technique to handle the nation’s wildfire disaster. It plans to hold out discount work on 21 landscapes throughout 134 “firesheds” within the Western U.S.
All of which means there may be extra work than guide labor can accomplish alone. Kodama claimed that its techniques are extra essential than ever.
“I was a wildland firefighter. I spent three seasons out within the entrance strains on a number of the largest fires in California state historical past,” Sedlak mentioned. “I noticed a pattern that emergency response assets can solely accomplish that a lot, and with a purpose to actually handle the wildfire disaster, we have to not solely maintain that suppression workforce. We [also] really want to give attention to the wildfire mitigation work.”
