Seattle-based, Carbon Robotics, unveils its third-generation Autonomous Weeder robot. The solution is designed to drive through a field, identify unwanted weeds from the crop plants, and then individually destroy the unwanted plants. The machine leverages robotics, artificial intelligence (AI), and laser technology to safely and effectively drive through crop fields to identify, target and eliminate weeds. The platform is so popular that the company completely sold out its production units for 2021 and is now taking orders for 2022.

At the core of the machine is a high-power laser that “zaps” the weeds using high intensity thermal energy to destroy an individual plant, without disturbing the soil. As a result, farmers can become more eco-friendly and use fewer herbicides. The result is a solution that help farmers achieve or maintain organic growing certification, while reducing the costs in manual labor, chemicals and other resources.

“AI and deep learning technology are creating efficiencies across a variety of industries and we’re excited to apply it to agriculture,” said Carbon Robotics CEO and Founder, Paul Mikesell. “Farmers, and others in the global food supply chain, are innovating now more than ever to keep the world fed. Our goal at Carbon Robotics is to create tools that address their most challenging problems, including weed management and elimination.”

By deploying robots created by Carbon Robotics, farmers will experience the following benefits:

  •  A significant increase in crop yield and quality: 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 costs: Automated 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 practices: Traditional 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 farming: One 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.

Carbon Robotics’ groundbreaking technology is designed for row crops with 200 acres to tens of thousands of acres. A single robot will weed 15-20 acres per day and replace several deployments of hand weeding crews. Since its founding in 2018, the company has worked closely with farmers to develop its technology, which supports effective and efficient weed elimination for both conventional and organic farmers. The robots have undergone beta testing on specialty crops farms, working on fields with a variety of crops, including broccoli and onions.

The robot weighs 4,350 kg (9,500 lbs), has a track width of 2,032 mm (80 in), a wheelbase of 2,794 mm (110 in). It can drive autonomously through the field at speeds up to 2,235 mm/sec (5 mph), and cover approximately 15-20 acres/day.

“This is one of the most innovative and valuable technologies that I’ve seen as a farmer,” said James Johnson of Carzalia Farm, who has utilized Carbon Robotics’ technology on his farm. “I expect the robots to go mainstream because of how effectively they address some of farming’s most critical issues, including the overuse of chemicals, process efficiency and labor. These robots work with a variety of crops, are autonomous and organic. The sky’s the limit.”

Carbon Robotics’ 2021 models have already sold out, but new models for the 2022 growing season are available for pre-order. Carbon Robotics offers a leasing option, which makes the robots more accessible to smaller farms with less acreage. The company will continue to explore new robot models and capabilities to help farmers improve efficiency and reliability across a variety of tasks.
