In August 2025, Nvidia and Carbon Robotics announced a partnership to launch a new robotic farming system that clears weeds automatically. The technology combines high-power lasers with advanced computer chips to identify and destroy unwanted plants.
The main model, the LaserWeeder G2 600, is a 20-foot wide machine towed by a tractor. Carbon Robotics reported that the machine uses 24 computer chips to control its 24 lasers. The company says the device can destroy 600,000 weeds per hour—about 167 weeds every second. At this speed, one unit can do as much work as 75 farmworkers.
The weeding system also includes a self-driving feature for tractors. This technology aims to solve the global shortage of tractor drivers by allowing the machines to operate on their own. To ensure safety during long shifts, workers monitor the system from a remote control center.
To keep crops safe, the technology uses a specialized AI program to tell the difference between weeds and crops. The system is accurate to less than a millimeter. This precision ensures that lasers hit only the weeds while the crops remain untouched.
Other Models
Carbon Robotics also developed the G2 200, a more compact version for use in smaller fields or different crop layouts. This unit is roughly 9 feet long, 7 feet wide, and 10 feet tall. It requires a 110-horsepower tractor strong enough to lift the 6,500-pound machine.
While the technology saves a lot of work, using high-power lasers on farms carries risks. Potential hazards include eye or skin injuries to people nearby and the danger of field fires in dry conditions. There are also performance limits; if the laser does not destroy the entire root, the weed may grow back.
