The U.S. is presently dealing with a wildfire disaster. In 2022, wildfires burned over 7.5 million acres of land, in keeping with the Nationwide Facilities for Environmental Data (NCEI). The Cybersecurity & Infrastructure Safety Company has estimated that wildfires have precipitated $81.6 billion in injury from 2017 to 2021, an almost tenfold improve from 2012 to 2016. Kodama Techniques Inc. is one firm providing a potential 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 is likely to 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 larger competitors for assets amongst flora in these areas, making them extra weak 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, usually weaker, bushes is able to burn.
Forestry is labor-intensive
Many authorities businesses and personal landowners are actually centered on eradicating materials from the forests to scale back potential gasoline hundreds. 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 activity. First, foresters are required for undertaking planning and environmental evaluation. 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 vans to go to numerous locations like sawmills or processing services. A single undertaking 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 remedy targets. There are even fewer utilizing robotics.
Kodama Techniques, 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 forestall wildfires from burning uncontrolled
Whereas a number of firms are utilizing robotics and synthetic intelligence to detect and suppress wildfires, Kodama is without doubt one of the few taking a extra proactive strategy by specializing in forest thinning.
“My background is in robotics and agriculture, and I’ve seen loads of know-how adoption within the agriculture house,” stated Merritt Jenkins, co-founder and CEO of Kodama. “And once I began exploring forest administration, I didn’t see the identical fee of know-how adoption.”
Forest thinning at scale requires numerous varieties of heavy equipment. In a single strategy 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 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 kind, stack, and cargo the logs onto a truck for transportation. As soon as the bushes are lower down, a couple of issues may occur, in keeping with Jenkins.
“In case you are inside a cost-effective transport distance from a sawmill, and it’s stable, 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 simply 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 may possibly take this materials there.
However most of this small-diameter materials finally ends up being piled and burned. This is the reason Kodama is creating a undertaking to retailer this materials as carbon storage, stated Jenkins. The state of California lately 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 lots of of years in dry, anaerobic storage,” Jenkins stated. “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 an alternative, you possibly can lock that carbon away for lots of of years.”
Kodama stated its key differentiator can also 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 stated. “The preliminary focus is the skidder.”

Kodama Techniques builds an autonomous skidder
“The skidder is mostly touring alongside the identical trails many instances,” Jenkins stated. “That is a chance for automation as a result of you possibly can map it after which comply with inside a map.”
The Kodama crew 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 unlock these very expert operators to do different high-value work on the undertaking websites,” stated Sedlak.
“The skid path navigation is autonomous, and there are particular extra dexterous points of the operation the place we take over teleoperation,” Jenkins stated. “And that teleoperation continues to be native, so that you’re on the undertaking website if 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 stated.
Labor is a serious problem for this trade, he added. There aren’t loads of younger folks wanting to enter the sphere, and working heavy equipment could be exhausting on the physique, noticed Jenkins.
Kodama stated it’s additionally working to allow teleoperation from offsite places to eradicate lengthy commutes to websites and develop the operator workforce. In accordance with the crew, some staff drive as much as two hours to get to the work website each day.
Up to now, the Kodama crew has efficiently demonstrated its semi-autonomous skidder in business 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
In recent times, authorities businesses have established initiatives aimed toward stopping catastrophic wildfires, and plenty 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 weak forest land per 12 months 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 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 that there may be extra work than handbook labor can accomplish alone. Kodama claimed that its methods are extra essential than ever.
“I was a wildland firefighter. I spent three seasons out within the entrance strains on among the largest fires in California state historical past,” Sedlak stated. “I noticed a pattern that emergency response assets can solely accomplish that a lot, and with a view to actually handle the wildfire disaster, we have to not solely maintain that suppression workforce. We [also] really want to deal with the wildfire mitigation work.”
