Robot One vs Inter-Plant Weeder SA-AI
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Solar-assisted laser weeding robot from Almkerk-based Pixelfarming Robotics — high-power laser modules burst weed cells at the two-leaf stage, chemical-free. Two frame sizes (3.20–3.60 m and 5.80–6.20 m working width) with 360°-rotating wheel units for configurable track widths; four 48 V hot-swappable batteries topped up by roof solar panels, optional diesel range extender for 24/7 work. Machines are working on farms in Europe and Canada; delivery 16–20 working weeks by production batch.
Best for: Fine vegetable and specialty growers (spinach, onion, babyleaf, leek, chicory, herbs, tulips) wanting chemical-free, no-till-disturbance weed control with an open, retrainable crop-detection platform.Tractor-mounted, chemical-free in-row weeder from SPAPPERI N.T. S.R.L. (Città di Castello, Italy; est. 1964). A hydraulic PTO-driven frame (1-4 rows) carries per-row "BOX AI" units — a 3D camera plus AI vision developed with Czech partner Ullmanna — that detect each plant's root and drive independent vertical rotary tillers or fixed knives to weed within the row. Spapperi's own brochure calls it both "SA-IA" and "SA-AI"; the product is marketed via that brochure and lead-gen listings rather than a dedicated page on Spapperi's main site as of this check.
Best for: Commercial vegetable and root-crop growers (Spapperi's own examples include lettuce, cabbage, pumpkin and sugar beet) who already run an appropriately-sized tractor with rear hydraulics and want mechanical in-row weed control without GPS guidance or chemical herbicides.| Robot One Verified 2026-07-16 | Inter-Plant Weeder SA-AI Verified 2026-07-19 | |

| Specifications | ||
| Power source | Solar + battery — four 48 V hot-swappable batteries, roof solar panels; optional diesel range extender for 24/7 hybrid operation | Tractor PTO-driven hydraulics — dedicated independent hydraulic circuit per weeding element, shared oil tank |
| Required tractor power | Is the vehicle (autonomous laser tool carrier) | Not disclosed — Spapperi specifies PTO-driven hydraulic transmission but publishes no minimum tractor horsepower figure for the SA-AI |
| Dimensions | Working widths 3.20/3.40/3.60 m (Robot One 3.60) or 5.80/6.00/6.20 m (Robot One 6.20); transport width 1.80–2.20 m | Not disclosed — modular frame (1-4 rows, single or double planting-row spacing); overall width/length vary by configuration |
| Weight | Not disclosed | Not disclosed |
| Min farm size | Not disclosed | Not disclosed — no hectare threshold published; the multi-row tractor-mounted design targets commercial vegetable/root-crop operations |
| Productivity | ~10,000 laser shots/h per laser unit; e.g. 300TR with 10 lasers ran 200 m/h in babyleaf at 90% kill rate (vendor); working speed 150–1,000 m/h | 4,500-8,500 plants/hour per row, depending on in-plant spacing |
| Max speed | Working speed 150–1,000 m/h depending on configuration and weed pressure | Not disclosed |
| Sensors | Camera-based crop/weed detection · GPS + RTK autonomous navigation · optional bedtop lighting for improved detection | 3D camera plus integrated lighting per weeding element ("BOX AI", AI vision by Ullmanna) for day/night plant-root detection; anti-collision sensors on each element arm; central "Power Box" CPU with GPS and internet connectivity |

| Native price | Not disclosed | Not disclosed |
| Business model | Quote-based purchase direct or via dealers (NL, DE, UK, Scandinavia, FR, CA); delivery 16–20 working weeks by production batch | Buy — tractor-mounted implement sold direct from Spapperi NT S.r.l. (Città di Castello, Italy); AI vision developed with Czech partner Ullmanna, integrated as Spapperi's "BOX AI - Ullmanna System" |
| Ongoing cost | Battery cycling; laser module service; 4G/5G data; optional diesel for range extender | Interchangeable rotary-tiller/knife wear parts; hydraulic oil and PTO-pump upkeep; AI crop models update automatically over the internet (Spapperi states a new crop can be added in about 6 hours) |
| Key outcome | ||
| Best verified result | Herbicide use Chemical-free laser weeding (exothermic cell burst at two-leaf stage) · vendor | In-row weeding labour Vendor testimonial states each row unit replaces about 10 manual workers · vendor |
| EU context | ||
| CE marking | CE marked — EU-built series product operating on European farms | Not disclosed — no CE-marking statement found for the SA-AI on Spapperi's site, its brochure, or the dealer-contact page |
| Machinery Regulation | Dutch-built; sold with a continuous-human-supervision requirement to meet current autonomous-machinery rules | Not disclosed — would fall under Regulation (EU) 2023/1230 as a mounted implement with AI-driven functions if placed on the EU market; no explicit compliance statement found |
| CAP subsidy | Chemical-free weeding supports CAP eco-scheme and pesticide-reduction goals; solar assist reduces energy footprint | Not disclosed — mechanical/AI in-row weeding removes herbicide use, which is relevant to CAP eco-schemes rewarding reduced chemical inputs, but Spapperi does not tie the SA-AI to CAP explicitly |
