A NEW weeding robot that uniquely uses lasers to 'exterminate the enemy', has been released by Carbon Robotics in the US.

The Seattle-based company has released its third generation Autonomous Weeder and this one uses a combination of robotics, artificial intelligence (AI), and laser technology, to safely and effectively allow it to drive through crop fields to identify, target and eliminate weeds.

However, if you are on the market for one of these robots, you will have to wait until 2022 as all the 2021 models have already sold out. New models for the 2022 growing season are available for pre-order.

Unlike other weeding technologies, the robots utilise high-power lasers to eradicate weeds through thermal energy, without disturbing the soil. Also, farmers who use these automated robots have the ability to reduce their herbicide use, reduce labour and costs while at the same time improving crop yields.

Carbon Robotics CEO and founder, Paul Mikesell, told The SF: “AI and deep learning technology are creating efficiencies across a variety of industries and we’re excited to apply it to agriculture. 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 these robots created, farmers can experience benefits such as:

* 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 labour as well as reduce the use of crop inputs such as herbicides and fertilisers. Labour 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 labour provides farmers with a more realistic path to classifying their crops as organic.

Carbon Robotics’ ground-breaking technology is designed for use in row crops with 200 acres to thousands of acres. A single robot can weed 15-20 acres per day and replace several deployments of hand weeding crews which are sometimes used on organic units.

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.

James Johnson, of Carzalia Farm, has used the laser weed killing technology on his farm and has been well pleased. He said: “This is one of the most innovative and valuable technologies that I’ve seen as a farmer. 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 labour.

"These robots can work with a variety of crops, are autonomous and organic. The sky’s the limit for this technology,” pointed out James.
