Four Growers, Inc. · United States

Pittsburgh-built autonomous greenhouse tomato harvester running the first operational robot fleets in Dutch greenhouses — snack, plum and cherry tomatoes picked by suction with stereo vision at up to 43 kg/h and 98% ripe-detection precision. Fits existing commercial greenhouses with minimal modification; used by grower Westburg and at Syngenta's TomatoVision research facility.

Best for: Large glasshouse tomato operations in the Netherlands or US wanting fleet harvesting of snack/cherry tomatoes plus per-row yield heatmaps and forecasting.
MetoMotion Ltd · Israel

Israeli dual-arm greenhouse robot that harvests vine tomatoes on pipe-rail systems using an AI 3D vision system, developed with Dutch greenhouse-tech partner Ridder. Running in Dutch greenhouses — validated at grower Lans in the 2025 NPPL-R trial by Wageningen UR (up to ~90% of eligible vines harvested, operator supervision still required) and picking ToBRFV-resistant varieties at Axia Vegetable Seeds' demo greenhouse.

Best for: Large Dutch-style vine-tomato greenhouses on pipe rails wanting to automate harvest labour, with tolerance for a validation-stage machine that needs supervision and a crop structure adapted to robotic picking.
