The roots of the Carbon Robotics LaserWeeder implement lay in their autonomous LaserWeeder. The implement deploys 30 150 Watt CO₂ 10.6 μm lasers with tracking cameras assisted by 9 led bedtop lighting bars and 12 hi-res predict cameras. The LaserWeeder has a 6.1 m (20 feet) working width while the wheel tracks are adjustable for 60-84 inch rows. It can target almost any weed unless the weed is completely covered by dirt or plants. The implement has been very effective in targeting and eliminating weeds very close to the crops, much closer than any previous method. This prevents damage to the crop and its root system. Each of the 30 lasers outputs 150 Watt, consuming roughly 750 Watt each, while the entire implement consumes about 40 kW.

The LaserWeeder can handle weeds up to 5 cm (2 inch) in diameter, depending on the species. The size of the weed will dictate how long the laser is applying thermal energy to the weed. The larger the weed, the longer the laser will target it. The patented lighting system, creating light that is 4 times brighter than the sun, enables the LaserWeeder to operate day and night.
