Description

The SAMI 4.0 is towed behind a tractor in multi-unit formation (usually twenty per field). Using machine vision, it detects only the broccoli heads that ready to be harvested, with the capacity in development to harvest other vegetables (lettuce expected by end of 2022). Cutting is done with a water jet. The SAMI 4.0 also inspects and classifies harvested broccoli, boxes the heads, palletizes the boxes, and places them on a trailer. Eventually, SAMI will also be adapted to perform other tasks, such as weed detection and removal, insect identification, seeding, detection and treatment of diseased plants, soil analysis (moisture, fertilizer, pH) and more.
