The U.S. is at the moment going through a wildfire disaster. In 2022, wildfires burned over 7.5 million acres of land, in response to the Nationwide Facilities for Environmental Info (NCEI). The Cybersecurity & Infrastructure Safety Company has estimated that wildfires have triggered $81.6 billion in harm from 2017 to 2021, a virtually tenfold enhance from 2012 to 2016. Kodama Programs Inc. is one firm providing a attainable answer.
A number of components have contributed to the present disaster. These embody a warming local weather and a rising variety of houses within the wildland-urban interface, in response to the U.S. Division of Agriculture (USDA) Forest Service. However you may be stunned to be taught that overgrown forests are additionally a key contributor, particularly within the Western U.S.
Traditionally, forests within the West have been a lot much less dense than they’re at the moment. Overstocked forests have resulted in better competitors for assets amongst plants 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 companies 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 dangerous vegetation. Their targets are to enhance forest well being situations and preserve wildfires from spreading uncontrolled.
Forest thinning isn’t a easy process. First, foresters are required for challenge planning and environmental evaluation. 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 challenge cycle might take months, and even years.
It’s a labor-intensive and bodily demanding job, and there aren’t sufficient organizations to satisfy state and federal therapy targets. 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 companies are calling for proper now,” James Sedlak, co-lead for operations and communications at Kodama, advised The Robotic 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 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 loads of expertise adoption within the agriculture area,” stated Merritt Jenkins, co-founder and CEO of Kodama. “And once I began exploring forest administration, I didn’t see the identical charge of expertise adoption.”
Forest thinning at scale requires varied varieties 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, just a few issues might occur, in response to Jenkins.
“In case you are inside a cheap transport distance from a sawmill, and it’s strong, high quality materials, you then 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 gained’t settle for them. If the corporate is working inside a cheap transport distance of a biomass energy plant, it may take this materials there.
However most of this small-diameter materials finally ends up being piled and burned. This is the reason Kodama is growing a challenge to retailer this materials as carbon storage, stated Jenkins. The state of California just lately 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 a whole lot of years in dry, anaerobic storage,” Jenkins stated. “With pile burning, nearly all of that carbon that’s saved within the biomass finally ends up going into the environment as CO2 emissions. As a substitute, you may lock that carbon away for a whole lot of years.”
Kodama stated its key differentiator can also be aboveground. It’s growing remote-controlled and autonomous expertise for equipment within the woods to enhance the security and productiveness of forest operations.
“Our objective is to have semi-autonomous processes all through a forest-thinning operation,” Jenkins stated. “The preliminary focus is the skidder.”

Kodama Programs builds an autonomous skidder
“The skidder is mostly touring alongside the identical trails many occasions,” Jenkins stated. “That is a chance for automation as a result of you may map it after which observe inside a map.”
The Kodama group equips its semi-autonomous skidders with two major sorts of sensors: cameras and lidar. Because the skidder travels via 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 liberate these very expert operators to do different high-value work on the challenge websites,” stated Sedlak.
“The skid path navigation is autonomous, and there are specific extra dexterous elements of the operation the place we take over teleoperation,” Jenkins stated. “And that teleoperation continues to be native, so that you’re on the challenge website if you’re teleoperating.”
Kodama integrates its expertise with the machine’s controls. Something an operator can management from throughout the cab, the corporate can management remotely, Jenkins stated.
Labor is a significant problem for this trade, he added. There aren’t loads of younger individuals wanting to enter the sphere, and working heavy equipment will be onerous on the physique, noticed Jenkins.
Kodama stated it’s additionally working to allow teleoperation from offsite areas to remove lengthy commutes to websites and increase the operator workforce. Based on the group, some employees drive as much as two hours to get to the work website daily.
Thus far, the Kodama group 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 stated its focus extends past the skidder, with plans to automate processing and loading operations.

Forest thinning transferring to the forefront of presidency coverage
Lately, authorities companies have established initiatives geared toward stopping catastrophic wildfires, and lots of of them embody forest-thinning targets.
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, shield habitat and organic range, and assist the state meet its local weather goals. 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 deal with 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 traces on among the greatest fires in California state historical past,” Sedlak stated. “I noticed a pattern that emergency response assets can solely accomplish that a lot, and to be able to actually handle the wildfire disaster, we have to not solely maintain that suppression workforce. We [also] actually need to give attention to the wildfire mitigation work.”
