Overview
Overview
SGT Agribots are autonomous tracked field robots that drive crop rows, identify weeds vs crop plants with AI vision, and remove weeds mechanically, with a low-power laser, or with precision spot-spray — cutting herbicide use by 70-95% versus blanket application.
Built for row crops (vegetables, cotton, soybeans, sugar beet) and high-value organic plots where chemical residue, labour cost, or both, are pain points. Robots run day or night on solar + battery, send live progress and weed counts to a cloud dashboard, and the farmer schedules the next mission from a phone.
- AI weed/crop classifier — 96%+ accuracy on common species, on-device inference
- Three treatment modes — mechanical hoe, low-power laser, or precision spot-spray
- Solar + battery — multi-shift autonomy, automatic charging dock
- Herbicide cut 70-95% — only weeds get treated, not the whole row
How It Works
- Map — the bot RTK-maps the field on first pass, learns row spacing and crop type.
- Detect — a downward-facing stereo camera runs U-Net segmentation + classifier on each frame (38 FPS on an embedded Jetson).
- Decide — for each detected plant the bot picks an action: ignore (crop), mechanical hoe, laser shot, or 5-ml spot-spray.
- Act — a 3-DOF arm reaches the target in < 0.5 s; the bot continues at 2-4 km/h.
- Report — every weed hit and crop kept is logged, geo-tagged, and pushed to the cloud for the field report.
Features
- Computer vision — RGB-D camera, U-Net segmentation, WeedNet classifier v6 (96.4%)
- Tri-mode treatment — mechanical hoe, 30 W laser, 5-ml spot-spray nozzle
- RTK-GPS + IMU — centimetre accuracy, headland turning, row following
- Solar canopy — 200 W on top of chassis, extends runtime 30-50%
- Auto charging dock — solar-fed field dock; bot returns when battery low
- Edge fleet OTA — new models pushed in batches, rollback on failure
- Web dashboard — fleet status, weed counts, herbicide saved, per-bot reports
- Open API — REST + MQTT integration with farm-management systems
Use Cases
- Vegetable rows — carrot, onion, lettuce, brassica weeding without chemical residue
- Cotton & soybean — early-season weeding before canopy closes
- Sugar beet & corn — high-value crops where herbicide cost is significant
- Organic farms — chemical-free weeding meets organic certification
- Trial & research plots — repeatable, logged treatments for agronomy data
- Contract weeding — service-bureau billed per acre
