Founded in 2018 by Paul Mikesell, the company aims to address labor shortages, reduce costs, and promote sustainable farming practices. Its flagship product, the LaserWeeder, is an autonomous or tractor-pulled robotic system that uses computer vision, AI deep learning, and high-powered lasers to identify and eliminate weeds with precision. The LaserWeeder targets weeds at the sub-millimeter level, avoiding crops and reducing the need for chemical herbicides or manual labor.
Effectiveness of Carbon Robotics' Solutions
The effectiveness of Carbon Robotics' technology, particularly the LaserWeeder, can be evaluated based on its impact on weed control, cost reduction, crop yield, and environmental sustainability. While comprehensive, independent, long-term studies are limited due to the technology’s relatively recent introduction, available data from the company and user feedback provide insight:
-
Weed Control Efficiency:
-
The LaserWeeder uses AI to distinguish weeds from crops and targets them with lasers, reportedly killing over 100,000 weeds per hour with its earlier autonomous model (featuring 8 laser modules). The 2022 model, with 30 lasers, claims an average capacity of 2 acres per hour. This precision and speed suggest a significant improvement over traditional methods like hand-weeding or mechanical tilling, which can be slower and less selective.
-
-
Cost Reduction:
-
Carbon Robotics claims the LaserWeeder can reduce weed control costs by up to 80%. This is attributed to eliminating herbicide expenses and reducing labor needs—potentially replacing the work of dozens of farm workers. Farmers report a payback period of 1-3 years, depending on farm size and usage, which aligns with testimonials from large-scale growers like Grimmway Farms and Duncan Family Farms.
-
-
Crop Yield and Soil Health:
-
By avoiding herbicides, the LaserWeeder supports healthier soil ecosystems and reduces chemical residues, potentially leading to improved crop quality and yield over time. The non-invasive laser approach also minimizes soil disturbance compared to mechanical weeding, preserving soil structure. However, specific quantitative data on yield increases is not widely published and may vary by crop and region.
-
-
Sustainability:
-
The technology promotes organic farming by offering a chemical-free weed control alternative, aligning with growing consumer demand for sustainable produce. It also reduces the carbon footprint associated with herbicide production and application, though the energy use of the lasers themselves (powered by diesel generators or tractor systems in some models) could offset some of these gains if not sourced renewably.
-
Comparison to Traditional Methods
-
Manual Weeding: Far less efficient (e.g., a human worker might weed 1-2 acres per day versus the LaserWeeder’s 2 acres per hour) and increasingly impractical due to labor shortages.
-
Herbicides: Effective but costly, environmentally damaging, and facing regulatory scrutiny (e.g., glyphosate concerns). The LaserWeeder avoids these downsides but requires a significant upfront investment (pricing isn’t public but likely in the tens to hundreds of thousands of dollars).
-
Mechanical Weeding: Cheaper initially but less precise, often damaging crops or soil, and requiring more frequent passes than the LaserWeeder’s targeted approach.
Are They More Effective?
Carbon Robotics’ LaserWeeder appears more effective than traditional methods in terms of precision, labor savings, and environmental impact, particularly for large-scale specialty crop farms (e.g., 500+ acres). Its ability to cut weed control costs by up to 80% and handle tasks equivalent to 75 farm workers (as claimed by the company) suggests a strong return on investment for such operations. However, effectiveness depends on context:
-
Pros: High efficiency, scalability, and sustainability benefits make it a game-changer for farms facing labor shortages or seeking organic certification.
-
Cons: High initial costs, reliance on suitable farm infrastructure (e.g., row crops), and limited independent data on long-term yield impacts mean it’s not universally superior. Smaller farms or those with diverse crops may find it less practical.
In summary, Carbon Robotics is a leader in AI-driven agricultural robotics, and the LaserWeeder is likely more effective than traditional weed control for large, tech-adopting farms. Its full potential will become clearer as adoption grows and more data emerges. For now, it’s a promising step toward efficient, sustainable farming, backed by strong anecdotal evidence from users and the company’s rapid expansion (e.g., tripling demand in 2023).
The American manufacturer Carbon Robotics is introducing the LaserWeeder G2 to the market. This is the second generation of the weed control machine that operates with laser beams. According to the manufacturer, this version is faster, lighter, and available in various working widths.
Like its predecessor, this latest generation of autonomous field robots from Carbon Robotics is designed for precision weed control without herbicides. According to the American manufacturer, the LaserWeeder G2 operates faster and is lighter than the first generation. Due to its modular design, the LaserWeeder G2 is available in different working widths.
The field robot combines computer vision, AI deep learning technology, robotics, and lasers to distinguish crops from weeds and eliminate the weeds using laser beams.
LaserWeeder G2 works twice as fast
According to the American company Carbon Robotics, the LaserWeeder G2 operates twice as fast in the field as the first version. This is made possible by new 240-watt lasers (previously 150-watt) and more advanced graphics processors (GPUs) that analyse large volumes of images more quickly. The more powerful lasers require less time to irradiate and eliminate a weed plant.
The LaserWeeder is available in working widths ranging from 2 to 18.3 meters. The smallest version weighs 1.9 tons, while the 6-meter-wide model now weighs 3,266 kg (previously 4.3 tons).
