AX-1
Kilter AS · Norway
Norwegian ultra-precision weeding robot for open-field vegetables — an AI vision system detects individual weeds and a patented Single-Drop nozzle (SDT) fires one micro-droplet of herbicide directly onto each weed at 6x6mm resolution, cutting herbicide input by a manufacturer-claimed average of 96.6%. Independently tested by Wageningen University & Research at over 99% spray-drift reduction (Dutch DRT99, the system's highest class), and commercially deployed since 2021 across Norway, Sweden, Germany, the Netherlands and Australia, with a 2025 Kubota partnership now expanding EU dealer-network sales.
At a glance
Best for
Open-field vegetable and root-crop growers (carrots, onions, beets, celery/celeriac, spinach, salads, parsley and similar) in Norway and neighbouring EU markets who still spray herbicide and want to sharply cut volume and drift without switching to purely mechanical or laser weeding.
Avoid if
You need one machine to also seed, till or harvest — AX-1 only detects weeds and micro-doses herbicide onto them; it doesn't replace mechanical weed control or other field operations, and Kilter does not publish a price list (quotes are consultative, farm-by-farm).
Not suitable for
Cereals and broadacre row crops (maize, soybeans), orchards and vineyards — Kilter's trained classifiers currently cover open-field vegetables and root crops only; and farms wanting a single machine for multiple operations beyond weeding.
Specifications
Power sourceElectric drive with a small onboard petrol generator (per GOFAR robotics database; not itemized on the manufacturer's own site)
Required tractor powerNot required (self-propelled autonomous unit)
DimensionsApprox. 220 x 215 x 150 cm (third-party listing; not published by Kilter)
Weight280 kg dry / 365 kg wet (GOFAR database; distributed to minimise soil compaction)

ProductivityNot disclosed — third-party estimates conflict (0.33-1 ha/hr) and Kilter does not publish a figure
Max speedUp to 2 km/h (third-party listing; not published by Kilter)
SensorsAI vision with a deep-learning neural network for real-time weed/crop detection at 6x6mm targeting resolution; RTK-GNSS (dual-antenna) and IMU for autonomous navigation (third-party listing)
ConnectivityWi-Fi and cellular connectivity; NTRIP corrections for centimetre-level RTK positioning (third-party listing)
Compatible toolsSingle Drop Technology (SDT) spray module — current generation SDT-N2 — applying a 1,150-micron VMD herbicide droplet every 6mm onto individually detected weeds; mechanically classified as a boom sprayer, compatible with any crop-registered agrochemical usable in a boom sprayer (avoid powdered formulations, which risk blockages)

EU context
CE markingNo explicit CE-marking statement found on Kilter's public materials; the AX-1 is sold and in active commercial/pilot use in EU member states (Sweden, Germany, Netherlands) and passed independent Dutch DRT99 spray-drift certification (WUR/TCT)
EU Machinery RegulationNot explicitly addressed by the manufacturer; as an autonomous field-spraying machine placed on EU markets, would fall under the autonomous-machine provisions of Regulation (EU) 2023/1230 if formally assessed
AI Act relevanceLimited-risk; onboard deep-learning vision system for real-time weed/crop detection and targeting
CAP subsidyPrecision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectives
