Prospr vs Solix
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.Solar-powered scouting and spot-spraying robot from Brazilian-founded Solinftec (global HQ West Lafayette, Indiana) — lives in the field 24/7, monitors up to 2 million plants a day and applies herbicide plant-by-plant; 100+ robots deployed, US acreage up 243% year-on-year into 2026.
Best for: Large US corn-belt and Brazilian row-crop operations wanting continuous in-field scouting plus targeted herbicide application without diesel or an operator.| Prospr Verified 2026-07-19 | Solix Verified 2026-07-16 | |
