AX-1 vs Robovator
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.
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.Tractor-mounted, vision-guided intra-row hoeing implement from Danish manufacturer F. Poulsen Engineering — a camera above each row spots individual plants and hydraulically swings weeding knives out and back around them, removing weeds between plants without touching the crop. Commercially sold since the early 2010s and independently trialled in US vegetable production; configurable from 5 to 31 rows and adjustable to 25–75 cm row spacing.
Best for: Vegetable, sugar-beet and row-crop growers with a suitable PTO tractor who want camera-guided mechanical in-row weeding to cut herbicide use and hand-weeding labour, across a wide range of farm scales (5- to 31-row configurations).| AX-1 Verified 2026-07-18 | Robovator Verified 2026-07-18 | |

| Specifications | ||
| Power source | Electric drive with a small onboard petrol generator (per GOFAR robotics database; not itemized on the manufacturer's own site) | Tractor-mounted implement, PTO-driven hydraulics (~1 hp per row) |
| Required tractor power | Not required (self-propelled autonomous unit) | 3-point-hitch mounted; requires tractor PTO shaft speed of at least 420 rpm (hydraulic pressure and lamps cut out below ~360 rpm) |
| Dimensions | Approx. 220 x 215 x 150 cm (third-party listing; not published by Kilter) | Configurable 5 to 31 rows; row spacing adjustable 25–75 cm (9–30 in); US-market spec sheet lists 6–12 lines per bed with 60–84 in bed spacing |
| Weight | 280 kg dry / 365 kg wet (GOFAR database; distributed to minimise soil compaction) | 700 kg (1,500 lb) base weight |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | Not disclosed — third-party estimates conflict (0.33-1 ha/hr) and Kilter does not publish a figure | Roughly 1.5–2 acres/hour depending on soil and plant conditions (per Pacific Ag Rentals, US distributor); manufacturer-stated field speed 2–8 km/h (1.2–5 mph) |
| Max speed | Up to 2 km/h (third-party listing; not published by Kilter) | 2–8 km/h (1.2–5 mph) |
| Sensors | AI 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) | One plant-detection camera per row for image-based crop location, functions in low light; automatic self-centring side-shift (±40 cm range, engages after ~1 m of travel) |
| Price & model | ||
| Price (EUR) | ≈€130,000 | Not disclosed |
| Native price | ≈€130,000 (third-party: Future Farming robot database — Kilter quotes individually) | Not disclosed |
| Business model | Buy — direct from Kilter AS (Langhus, Norway) via a consultative sales process (farm details submitted for a quote; no public price list), or through regional distributors such as Croplands (Australia). A Kubota partnership (announced at Agritechnica 2025) is expanding dealer-network sales in Germany and the Netherlands through 2025-2026. | Buy — tractor-mounted implement sold direct from F. Poulsen Engineering (Denmark) and via distributors, including Agri Evolution (Netherlands, EU) and Pacific Ag Rentals (Salinas, California, western US) |
| Ongoing cost | Herbicide/bio-herbicide refills (any crop-registered agrochemical usable in a boom sprayer, e.g. pelargonic acid); Single-Drop nozzle module (SDT-N2) wear parts. Specific service cost figures not disclosed. | Wear parts (weeding knives/blades, camera lens care), hydraulic fluid and PTO shaft maintenance; no software subscription published |
| Key outcome | ||
| Best verified result | Spray drift vs. a conventional reference sprayer More than 99% spray-drift reduction — qualifies for DRT99, the highest class in the Dutch drift-reduction classification system · independent | Intra-row weed removal vs. a standard cultivator +18 to +41 percentage points · independent |
| EU context | ||
| CE marking | No 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) | No CE-marking statement found in the manufacturer's public materials, so compliance is listed as not confirmed — although CE marking is legally required to place machinery on the EU market and F. Poulsen actively sells within the EU (Denmark, and via Netherlands distributor Agri Evolution) |
| Machinery Regulation | Not 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 | Tractor-mounted implement falling under the EU Machinery Regulation (EU) 2023/1230; the tractor operator remains in control at all times |
| CAP subsidy | Precision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectives | Herbicide-free/reduced mechanical in-row weeding supports CAP eco-scheme and organic-conversion measures |
