Osiris Agriculture · France

French autonomous field robot from Osiris Agriculture (Illies, Hauts-de-France; founded 2021) that self-navigates row crops via RTK-GNSS and delivers precision irrigation plus fertigation — nitrogen/potassium dosed into the water — through a foldable boom, generating its own electricity from the water flow as it runs (solar, diesel-generator or battery backup when off-water). Commercially sold since 2025 in northern France through distributor Verhaeghe Irrigation; Osiris itself lists crop-protection spraying as a future capability, not a current one.

Best for: Large-scale potato and vegetable growers in northern France (or similar row-crop regions) who already run hose-reel/boom irrigation and want to automate it while adding fertigation — the distributor cites roughly 25 ha as the economic break-even.
Saga Robotics AS · Norway

Norwegian autonomous UV-C robot that replaces fungicide sprays for powdery mildew control — working at night in UK tabletop strawberries (used by 13 leading growers, around 20–30% of the national tabletop crop) and California vineyards, where over 150 Thorvald 3.0 units ran the 2025 season. Delivered as a service rather than a machine sale, with a vineyard-specific model launched for 2026.

Best for: Larger tabletop strawberry and wine-grape operations in Saga's service regions (UK, US) wanting to cut fungicide programmes without buying or operating robots themselves.

Specifications
Power sourceElectric — onboard water-turbine generator produces power from the irrigation flow itself; solar panels, a diesel generator, or batteries back it up when not connected to a water sourceBattery-electric · 48 V Li-Ion 70 Ah (space for a second battery) · charges from a regular outlet
Required tractor powerNot required for operation (self-propelled); road transport between fields via tractor tow, with regulatory approval for that still pending per one sourceNot required (self-propelled modular platform)
Dimensions5.08 m long x 3.05 m wide x 3.43 m high; foldable boom extends to 40-44 m depending on configuration (sources vary between 24-40 m and up to 44 m)Modular platform; configuration-dependent, not disclosed
Weight12,000 kg~200 kg
Min farm sizeRoughly 25 ha (economic break-even point cited by French distributor Verhaeghe Irrigation)Not disclosed
ProductivityRoughly 25-40 ha irrigated per week (sources vary), applying about 20-30 mm of water per week; water flow up to 60 m3/hFleet-scale service: ~2,500 acres of US vineyard treated; ~20% of UK tabletop strawberry crop
Max speed100-250 m/h field travel speedTypically under 5 km/h in operation
SensorsRTK-GNSS plus inertial measurement unit for centimetre-level autonomous navigation; onboard cameras for plant growth and soil-moisture monitoringAutonomous navigation stack; crop-counting cameras (up to 3 million crop counts per robot per night, vendor claim)
Price & model
Price (EUR)€250,000Not disclosed
Native price€250,000Not disclosed
Business modelDirect purchase; base price ~€250,000 HT (excl. tax), indicative €200,000- 300,000 range reported depending on configuration (wheel count, boom width, hose length, tyres, guidance system) — versus roughly €100,000 HT for a traditional hose-reel-with-boom irrigator. Sold in northern France through distributor Verhaeghe Irrigation (Montdidier, Somme); Osiris Agriculture also sells and demonstrates directly.UV-C treatment as a service — Saga deploys, operates and maintains robot fleets; growers pay for treatment rather than buying machines
Ongoing costNot disclosed — no published subscription, per-hectare service fee, or consumables schedule found beyond the buyer-configured hardware options at purchase.Service fee (not published); no grower-side machine ownership

EU context
CE markingNot confirmed — no explicit CE-marking statement found on the manufacturer site or in trade press. Osiris is reported to be developing separate "autonomy certification" to run the robot without an on-site supervisor, implying current commercial operation is supervised.CE status not published; UV-C units carry light-exposure safety interlocks for night operation
Machinery RegulationPlaced on the French/EU market commercially since 2025; would fall under the autonomous-machine provisions of Regulation (EU) 2023/1230, but no explicit compliance statement was found in the sources checked.Placed on the EU/UK market by Saga Robotics; Regulation (EU) 2023/1230 autonomous-machine provisions apply
CAP subsidyPrecision water and fertiliser dosing could support CAP eco-scheme water-efficiency measures; no direct CAP linkage has been published by Osiris.Large pesticide reduction supports EU pesticide-reduction and eco-scheme goals (service currently UK/US/NO, not EU-27)
