Element vs AX-1
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
US solar-powered autonomous weeding robot from Aigen (Redmond, WA) that eliminates weeds mechanically with AI-guided ground strikes — no herbicide. The current gen2 platform (launched April 2025) widened its working crops to cotton, soy and sugar beet and runs a mesh-networked robotic "crew"; roughly 50 units were in field trials in North Dakota/Minnesota (Grand Farm) and California (Bowles Farming) through 2025; the 2024 and 2025 preorder rounds sold out in a day, and 2026 orderability is not independently confirmed.
Best for: US row-crop growers (cotton, soy, sugar beet) wanting to cut herbicide spend and pursue organic certification, and willing to run a multi-robot fleet rather than a single machine (Aigen's own example — ~5 robots to cover 160 acres / 65 ha in a season).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.| Element Verified 2026-07-18 | AX-1 Verified 2026-07-18 | |

| Specifications | ||
| Power source | Solar-electric — onboard solar panel with battery backup (gen2 carries ~50% more solar capacity than gen1); no fuel used | Electric drive with a small onboard petrol generator (per GOFAR robotics database; not itemized on the manufacturer's own site) |
| Required tractor power | Not required (self-propelled) | Not required (self-propelled autonomous unit) |
| Dimensions | Not disclosed | Approx. 220 x 215 x 150 cm (third-party listing; not published by Kilter) |
| Weight | Not disclosed | 280 kg dry / 365 kg wet (GOFAR database; distributed to minimise soil compaction) |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | Illustrative fleet example from Aigen: ~5 robots to cover 160 acres (65 ha) in a season; a single robot's seasonal capacity is 20-40 acres depending on weed density | Not disclosed — third-party estimates conflict (0.33-1 ha/hr) and Kilter does not publish a figure |
| Max speed | Not disclosed | Up to 2 km/h (third-party listing; not published by Kilter) |
| Sensors | Onboard stereo depth-vision cameras and onboard AI (gen2 has 4x the compute of gen1) for row-following and weed identification; mesh network lets robots coordinate as a "crew" | 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) |
| Price & model | ||
| Price (EUR) | ≈€44,000 (indicative conversion) | ≈€130,000 |
| Native price | $50,000 | ≈€130,000 (third-party: Future Farming robot database — Kilter quotes individually) |
| Business model | Buy — $50,000 per robot (confirmed on TechXplore, quoting Aigen). A working deployment is typically several robots (Aigen's own illustrative example — ~5 robots per 160 acres / 65 ha). 2024/2025 preorder rounds sold out in a day; 2026 orderability not independently confirmed. | 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. |
| Ongoing cost | Not disclosed — Aigen has not published ongoing service/software costs on its own materials. One third-party business-model summary cites an additional ~$20,000 per-fleet coordination/software fee, but that figure could not be confirmed on any primary or trade-press source, so it is not carried into this field. | 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. |
| Key outcome | ||
| Best verified result | Herbicide spend and organic-certification eligibility Zero-herbicide mechanical weeding in Grand Farm (ND) trial deployment — growers avoid herbicide spend and can pursue organic certification / premium pricing · independent | 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 |
| EU context | ||
| CE marking | No CE marking evidence found — no EU sales or service presence identified (US-only — ND, MN, CA field trials/deployments) | 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) |
| Machinery Regulation | Not applicable — not placed on the EU market | 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 |
| CAP subsidy | Not applicable — US-only company; no CAP relevance found | Precision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectives |
