Farmers can set a geofence with GPS coordinates beyond which the machine won’t travel. While the machine is self-driving in a field, it’ll require human intervention to move between fields or do anything really complicated, since Carbon Robotics is erring on the side of safety. And so our machines know what it’s actually looking at and can say, ‘Okay, it’s onion time, let’s kill the carrots.’”Ī Carbon Robotics autonomous laserweeder in a farmer's field. If there’s any leftover carrots you want to kill them and protect the onions.

In the second scenario, the carrots are now weeds. So in the first scenario, the carrots were the crop and everything that’s not a carrot you want to kill. You grow the carrots, harvest them, send them to market, hopefully make a nice profit. “It’s important for us to be able to know weeds and crops because these farmers do rotations. ‘this is a spinach,’ which is a crop that somebody might grow, and ‘this is a purslane,’ which is a weed that somebody may want to kill,” Mikesell told me. It drives 5 miles/hour and can clear 15-20 acres in a day. The Laserweeder drives itself with computer vision, finding the furrows in the fields, positioning itself with GPS, and searching for obstacles with LIDAR. They’re guided by 12 high-resolution cameras connected to AI systems that can recognize good crops from bad weeds. It boasts no fewer than eight independently-aimed 150-watt lasers, typically used for metal cutting, that can fire 20 times per second. The weeding machine is a beast at almost 10,000 pounds.

Until Carbon Robotics’ autonomous Laserweeder. “What happens to the land over time, where we wind up stripping out a lot of the essential micro bacteria that’s down there in the ground, we’re changing the way that things are composting in the ground and it’s causing a bunch of longer term issues with soil health,” says Mikesell.īesides human labor, which is not scalable, herbicides are pretty much the only answer.
