The U.S. is presently going through a wildfire disaster. In 2022, wildfires burned over 7.5 million acres of land, in line with the Nationwide Facilities for Environmental Info (NCEI). The Cybersecurity & Infrastructure Safety Company has estimated that wildfires have prompted $81.6 billion in injury from 2017 to 2021, a virtually tenfold improve from 2012 to 2016. Kodama Programs Inc. is one firm providing a attainable answer.
A number of elements have contributed to the present disaster. These embrace a warming local weather and a rising variety of properties within the wildland-urban interface, in line with the U.S. Division of Agriculture (USDA) Forest Service. However you could be shocked to be taught 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 immediately. Overstocked forests have resulted in higher competitors for sources amongst flora 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 masses. 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 activity. First, foresters are required for mission planning and environmental assessment. Subsequent, they create prescriptions for logging crews to chop choose bushes and different vegetation.
Then, a crew of employees hauls this materials out of the forest and masses it onto vehicles to go to varied locations like sawmills or processing amenities. A single mission cycle may 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 therapy 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, advised The Robotic Report.

Kodama works to stop wildfires from burning uncontrolled
Whereas a number of firms are utilizing robotics and synthetic intelligence to detect and suppress wildfires, Kodama is likely 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 numerous 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 fee of know-how adoption.”
Forest thinning at scale requires numerous sorts of heavy equipment. In a single method referred to 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 chopping 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 kind, stack, and cargo the logs onto a truck for transportation. As soon as the bushes are minimize down, a number of issues may occur, in line 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 simply too small, a sawmill gained’t settle for them. If the corporate is working inside a cost-effective transport distance of a biomass energy plant, it might take this materials there.
However most of this small-diameter materials finally ends up being piled and burned. Because of this Kodama is creating a mission to retailer this materials as carbon storage, mentioned Jenkins. The state of California not too long ago estimated that roughly 84% of fabric is left within the woods.
“We’re creating 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 ambiance as CO2 emissions. As a substitute, you possibly can lock that carbon away for tons of of years.”
Kodama mentioned its key differentiator can be aboveground. It’s creating remote-controlled and autonomous know-how for equipment within the woods to enhance the protection and productiveness of forest operations.
“Our aim 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 occasions,” Jenkins mentioned. “That is a chance for automation as a result of you possibly can map it after which observe inside a map.”
The Kodama staff equips its semi-autonomous skidders with two main 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 may liberate these very expert operators to do different high-value work on the mission websites,” mentioned Sedlak.
“The skid path navigation is autonomous, and there are specific extra dexterous facets of the operation the place we take over teleoperation,” Jenkins mentioned. “And that teleoperation continues to be native, so that you’re on the mission website while you’re teleoperating.”
Kodama integrates its know-how with the machine’s controls. Something an operator can management from throughout the cab, the corporate can management remotely, Jenkins mentioned.
Labor is a serious problem for this trade, he added. There aren’t numerous younger individuals trying to enter the sector, and working heavy equipment will be exhausting 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 employees drive as much as two hours to get to the work website daily.
Up to now, 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, notably 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 geared toward stopping catastrophic wildfires, and lots of of them embrace forest-thinning objectives.
In 2020, California and the U.S. Forest Service established a shared long-term technique to handle forests and rangelands focusing on 1 million acres of susceptible forest land per yr beginning in 2025.
The technique goals to scale back wildfire dangers, restore watersheds, defend habitat and organic range, and assist the state meet its local weather targets. It cited a transition towards unnaturally dense forests as a threat 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 because of this there’s extra work than handbook labor can accomplish alone. Kodama claimed that its programs 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 sources can solely achieve this a lot, and so as to actually deal with the wildfire disaster, we have to not solely maintain that suppression workforce. We [also] really want to deal with the wildfire mitigation work.”
