Agrobot (Soluciones Robóticas Agrícolas S.L.) · Spain

Spanish robotic strawberry harvester from Huelva with up to 24 independent picking arms that grip and cut the stem so fruit is never touched, guided by colour/infrared depth sensors and LiDAR. A long-running pioneer (field work in Huelva and California, early Driscoll's trials) — but Agrobot itself still labels the E-Series pre-commercial and 'not for sale, project on development' as of 2026, with thin recent public evidence of commercial deployments.

Best for: Watching, not buying — large strawberry growers tracking robotic harvest maturity; Agrobot remains one of the longest-running dedicated strawberry-harvest programmes in Europe.
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.
