Carbon Robotics - Autonomous Laserweeder
Carbon Robotics™ launched its Autonomous LaserWeeder™ in 2021 to provide farmers with an efficient and cost effective weed management solution. Leveraging deep-learning-based computer vision, the Autonomous LaserWeeder identifies, targets and eliminates weeds while driving autonomously over crop rows. Since its founding in 2018, Carbon Robotics has worked closely with farmers to develop this precision laserweeding technology, which supports sustainable and reliable weed elimination for both conventional and organic farmers. Carbon Robotics’ Autonomous LaserWeeders now serve as demo units, allowing specialty crop growers to see laserweeding’s proven efficiency, precision, and benefits when adopted.

Weeding Process
PATROL
The Carbon Robotics Autonomous Weeder runs day and night, using its GPS and computer vision guidance system to stay within the bounds of your field, navigate furrows, and automatically turn around for the next row.
IDENTIFY
High-resolution cameras scan your field, crops, and weeds in real time. A rugged, onboard supercomputer uses machine learning to identify invasive weeds (green) among your valuable crops — in milliseconds — all while rolling.
DESTROY
High-powered lasers target thermal energy at each weed’s meristem. The Autonomous Weeder can kill over 100,000 weeds/hour using eight simultaneously operating laser modules that deliver quick zaps on emerging weeds.
BENEFITS FOR FARMERS
By deploying Autonomous Weeder robots created by Carbon Robotics, farmers will experience the following benefits:
Laser-weeded onions (top) compared to herbicide-treated onions (bottom). Laser weeding improves crop quality and yield.
Lasers leave the soil microbiology undisturbed, unlike tillage. The lack of herbicides and soil disruption paves the way for a regenerative approach, which leads to healthy crops and higher yields.
A REDUCTION IN OVERALL COSTSAutomated robots enable farmers to reduce the highly variable cost of manual labor as well as reduce the use of crop inputs such as herbicides and fertilizers. Labor is often farmers’ biggest cost and crop inputs account for 28.2% of their total expenses. Reducing costs in both these areas is a huge benefit.
ADOPTION OF REGENERATIVE FARMING PRACTICESTraditional chemicals used by farmers, such as herbicides, deteriorate soil health and are tied to health problems in humans and other mammals. A laser-powered, autonomous weed management solution reduces or eliminates farmers’ needs for herbicides.
AN ECONOMICAL PATH TO ORGANIC FARMINGOne of the largest obstacles to organic farming is cost-effective weed control. A solution to weed management that doesn’t require herbicides or an increase in manual labor provides farmers with a more realistic path to classifying their crops as organic.
