Oscar vs Prospr
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.New Zealand-engineered autonomous spraying vehicle for orchards and vineyards, built by Robotics Plus (Tauranga, NZ) and sold/supported today through Yamaha Agriculture, formed when Yamaha Motor completed its acquisition of Robotics Plus in 2025. A hybrid diesel-electric drivetrain (Tier 4 generator + battery pack + independent wheel motors) drives RTK-GPS-guided autonomous spraying with quick-swap Q Series (foliar) and H Series (under-canopy herbicide) sprayers. Commercially deployed in the US, Australia and New Zealand; a published case study (Treasury Wine Estates, NZ) shows two units covering 300 ha of vineyard across eight 15-hour operating days.
Best for: Larger commercial orchard or vineyard operations in the US, Australia or New Zealand — the Treasury Wine Estates case study (two units, 300 ha, NZD 115,000/year net savings after subscription costs) shows the economics working at estate scale, backed by a real Yamaha Agriculture / Croplands / Burrows Tractor dealer network.| Oscar Verified 2026-07-19 | Prospr Verified 2026-07-19 | |

| Specifications | ||
| Power source | Electric — 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 source | Hybrid diesel-electric — Tier 4 diesel generator + regenerative braking + high-capacity battery pack, powering independent electric drive motors at each wheel |
| Required tractor power | Not required for operation (self-propelled); road transport between fields via tractor tow, with regulatory approval for that still pending per one source | Not required (self-propelled) — hybrid diesel-electric drivetrain, ~50 kW drive output |
| Dimensions | 5.08 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) | 5,240 x 1,950 x 3,600 mm (206 x 77 x 141 in, L x W x H); minimum row spacing 1.85 m (6.07 ft); minimum headland 7.1 m (23 ft), spot-turns around the rear axle |
| Weight | 12,000 kg | 2,000 kg / 4,409 lb (unladen, without payload) |
| Min farm size | Roughly 25 ha (economic break-even point cited by French distributor Verhaeghe Irrigation) | Not disclosed |
| Productivity | Roughly 25-40 ha irrigated per week (sources vary), applying about 20-30 mm of water per week; water flow up to 60 m3/h | 300 ha (740 ac) covered by two units across eight 15-hour operating days in the Treasury Wine Estates case study — about 1.3 ha/hr (3.2 ac/hr) per unit, up from 1 ha/hr (2.4 ac/hr) with a conventional tractor-mounted sprayer |
| Max speed | 100-250 m/h field travel speed | Not disclosed |
| Sensors | RTK-GNSS plus inertial measurement unit for centimetre-level autonomous navigation; onboard cameras for plant growth and soil-moisture monitoring | RTK GPS precision navigation; LiDAR + camera sensor fusion for obstacle detection and collision avoidance |
| Price & model | ||
| Price (EUR) | €250,000 | Not disclosed |
| Native price | €250,000 | Not disclosed |
| Business model | Direct 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. | Contact-sales / subscription-inclusive model — Yamaha Agriculture's own case study nets savings "after subscription costs" but no purchase price or subscription terms are published; sold direct and through the Yamaha Agriculture / Croplands (AU, NZ) / Burrows Tractor (US) dealer network. |
| Ongoing cost | Not disclosed — no published subscription, per-hectare service fee, or consumables schedule found beyond the buyer-configured hardware options at purchase. | Subscription-style cost referenced in published case studies but exact terms not disclosed; parts and preventative-maintenance kits supplied through the dealer network. |
| Key outcome | ||
| Best verified result | Water use vs. conventional hose-reel/cannon irrigation ~-30% (vendor commitment) · vendor | Vineyard spraying work rate +34% · vendor |
| EU context | ||
| CE marking | Not 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. | Not confirmed — no CE-marking evidence found; the product is not marketed or sold in the EU (deployment is US, Australia and New Zealand only) |
| Machinery Regulation | Placed 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. | Not applicable — no EU market presence found; would fall under Regulation (EU) 2023/1230 autonomous-machine provisions if ever placed on the EU market |
| CAP subsidy | Precision water and fertiliser dosing could support CAP eco-scheme water-efficiency measures; no direct CAP linkage has been published by Osiris. | Not applicable — outside the EU, no CAP relevance; sold in the US, Australia and New Zealand only |
