The Carbon Robotics LaserWeeder is a weeding robot by Carbon Robotics, priced at $750K-$1000K. It is commercially available and deployed on farms worldwide. Compatible crops include onions, carrots, broccoli, lettuce. It delivers up to 80% labor cost reduction.

The Carbon Robotics LaserWeeder is a cutting-edge agricultural implement that uses 30 high-power CO2 lasers to eliminate weeds with millimeter precision, achieving a kill rate of 200,000 weeds per hour. The system is pulled behind a standard tractor and uses 12 high-resolution cameras paired with deep-learning AI to distinguish weeds from crops in real time, even at speeds up to 6 mph. Because it uses thermal energy rather than chemicals, it delivers 100% chemical-free weed control, making it ideal for both organic and conventional operations. The LaserWeeder can operate day and night, with its computer vision system performing equally well in darkness using its own lighting array. It has seen rapid commercial adoption across onion, carrot, broccoli, and cotton farms in the western United States.
