Earth Rover sells first 10 CLAWS light-weeding robots at £150,000 each

British robotics firm Earth Rover has sold its first 10 CLAWS weeding robots, with another 15 under construction for customers — the moment the company crosses from prototype to paying deployments.

The autonomous machine kills weeds with concentrated pulses of light rather than lasers, herbicides or mechanical tools. CEO James Miller confirmed the pilot-production sales. CLAWS — Concentrated Light Autonomous Weeding and Scouting — uses cameras and AI to tell weeds from crops, then fires a short pulse of concentrated light at the weed's growing point, heating the tissue enough to kill it.

Why light pulses instead of lasers?

Unlike laser weeders, CLAWS focuses light at a specific point rather than using a collimated laser beam. Earth Rover claims this approach needs less energy than laser-based systems, though the company hasn't published independent comparative figures. A claim, in other words. A promising one, but a claim.

The distinction matters for anyone comparing robot weeding options. Energy consumption drives both battery sizing and running costs, and light-pulse systems position themselves as the thriftier alternative to the laser kits already on the market.

What are the machine's working specs?

The lightweight robot runs on batteries supported by solar power and can operate for up to 16 hours without a battery change — a full double shift in practice. Its adjustable track width ranges from 1.5 to 2 metres (4.9–6.6 ft), which suits bed configurations typical of vegetable and salad crops.

The cameras do double duty. Alongside weeding, they collect crop-monitoring data, including plant counts and crop health indicators — the scouting half of the acronym earning its keep.

What does it cost, and what does this change for growers?

The purchase price sits at approximately £150,000 (€170,000 / US$195,000, indicative conversions). Earth Rover claims a payback period of 1 to 3 years, depending on a farm's existing weeding costs. Handy caveat: independently verified figures for field capacity, weed control efficacy and operating costs per hectare are not yet available. Buyers are, for now, working largely on the manufacturer's numbers.

The company initially targets vegetable farms of around 100 hectares (247 acres), though it reports sales to smaller growers too. That's worth noting — early adoption trickling below the target segment suggests demand among specialised growers who face high hand-weeding and herbicide-restriction costs.

What happens next?

Earth Rover plans to expand into broadacre crops and seek additional investment in 2027. The immediate milestone, though, is already banked: first customer deliveries of a light-based weeder that isn't a laser, isn't a sprayer and isn't a hoe.

For vegetable growers weighing chemical-free weeding options, the practical watch-point is simple: independently verified capacity and per-hectare cost data. Until that lands, the 10 buyers are effectively running a very expensive — and very interesting — field trial.
