What autonomous weeding taught Kilter ↗

AX-1 has helped farmers avoid spraying more than 1 million litres of herbicide mixture in under 8 months, across 5 countries. Kilter (Anders Brevik) says the figure is telemetry — droplets logged at 1 µL each — compared with what conventional broadcast spraying would have used on the same area.

Kilter’s AX-1 is an autonomous in-row weeding robot that sprays micro-droplets of herbicide onto weeds rather than broadcasting a field. AI finds weeds and patented droplet technology aims herbicide at 6×6 mm accuracy, typically using pelargonic acid. With typical weed pressure around 5%, Kilter states an average 96.6% reduction in input use. The frame is modular and light; Kilter currently makes a distributed dry weight of 300 kg.

260 kg dry weight; 50 L tank; 6×6 mm Single Drop Technology; about 1 ha/hour; up to 95% herbicide reduction versus broadcast spraying; 24/7 operation; compatible with standard herbicides and bio-herbicides such as pelargonic acid.

Kilter’s own blog says AX-1 launched in 2021 and is in use in Norway, Sweden, Germany, and the Netherlands (carrots, onions, salad, beets), with three robots operating in Australia. CEO Anders Brevik is quoted there. An official Kilter YouTube video, “Kilter AX 1 Product Demo,” shows the Remote app and 6 mm outlets.
