The U.S. is at present going through a wildfire disaster. In 2022, wildfires burned over 7.5 million acres of land, in line with the Nationwide Facilities for Environmental Data (NCEI). The Cybersecurity & Infrastructure Safety Company has estimated that wildfires have induced $81.6 billion in harm from 2017 to 2021, an almost tenfold enhance from 2012 to 2016. Kodama Programs Inc. is one firm providing a doable resolution.
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 line with the U.S. Division of Agriculture (USDA) Forest Service. However you is perhaps shocked 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 present. 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, usually weaker, bushes is able to burn.
Forestry is labor-intensive
Many authorities businesses and personal landowners are actually targeted on eradicating materials from the forests to cut back potential gas hundreds. They’re turning to forest-thinning strategies that use machines to take away extra and dangerous vegetation. Their objectives are to enhance forest well being circumstances and maintain wildfires from spreading uncontrolled.
Forest thinning isn’t a easy process. First, foresters are required for undertaking 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 vans to move to varied 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 satisfy 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, informed 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 likely 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 a variety of expertise adoption within the agriculture house,” stated Merritt Jenkins, co-founder and CEO of Kodama. “And after I began exploring forest administration, I didn’t see the identical price of expertise adoption.”
Forest thinning at scale requires numerous forms 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 slicing web site 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 line with Jenkins.
“In case you are inside a cheap transport distance from a sawmill, and it’s strong, high quality materials, then you definately 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 cheap transport distance of a biomass energy plant, it could 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 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 growing 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, nearly all of that carbon that’s saved within the biomass finally ends up going into the environment as CO2 emissions. As an alternative, you possibly can lock that carbon away for lots of of years.”
Kodama stated its key differentiator can 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 aim 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 instances,” Jenkins stated. “That is a chance for automation as a result of you possibly can 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 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 facets 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 web site if you’re teleoperating.”
Kodama integrates its expertise 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 a variety of younger folks wanting to enter the sphere, and working heavy equipment will be laborious 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. In line with the group, some staff drive as much as two hours to get to the work web site day by day.
Up to now, 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, significantly 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 shifting to the forefront of presidency coverage
Lately, authorities businesses have established initiatives geared 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 focusing on 1 million acres of susceptible forest land per yr beginning in 2025.
The technique goals to cut 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 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’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 traces on a number of the greatest fires in California state historical past,” Sedlak stated. “I noticed a development that emergency response sources can solely achieve this a lot, and with a purpose to actually tackle the wildfire disaster, we have to not solely maintain that suppression workforce. We [also] really want to give attention to the wildfire mitigation work.”
