AI-Driven Sustainable Weed Managing Mobile Robot
Bibliographic record
Abstract
This study introduces a compact, autonomous mobile weed management robot designed to promote sustainable agricultural practices and enhance crop protection through effective early-stage weed management. Equipped with a laser-based system, the robot enables precise weed removal tailored to specific agricultural contexts. It employs an AI-driven image classification approach for weed detection, achieving a mean average precision (mAP) of 0.32 and a detection rate of 118 ms on a Raspberry Pi 5 platform. The robot features a two-degree-of-freedom arm for accurate laser positioning, with exposure duration dynamically adjusted based on identified weed species to minimize energy consumption and protect neighboring crops and soil. Field trials in Vancouver, Canada, and Arusha, Tanzania, demonstrated the robot’s effectiveness, achieving weed removal success rates of 97% and 96%, respectively, in a maximum of 60 seconds targeting pigweed, purslane, and nutsedge. Designed to be cost-efficient and scalable, this innovative system offers an environmentally sustainable solution for effective weed management, significantly reducing herbicide use and enhancing weed targeting precision. This research underscores the dual benefits of integrating autonomous technology into agriculture, improving productivity and sustainability while protecting crop health and ecosystems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
