Project preview
PreviewReserved for a hero capture, product walkthrough, or marketing frame.
Technologies used
- Python
- YOLOv8
- Computer Vision
- Robotics
Key features
- YOLOv8n pipelines tuned for field imagery and edge-friendly inference budgets
- Dataset curation and augmentation oriented toward crop and weed diversity
- Control paths that pair detections with actuation logic for safe field trials
- Python tooling for training, evaluation, and reproducible experiment tracking
Challenges solved
- Operating under variable lighting, dust, and occlusions common in outdoor rows
- Trading off model accuracy against latency on compute-limited robot hardware
- Grounding detections in reliable spatial frames for safe mechanical response
Architecture & engineering highlights
Diagram
Sense–decide–act loop: camera frames through a vision stack, fused with motion state, before commands reach the elimination mechanism.
Engineering highlights
Edge-first vision
Model choices and input resolutions aimed at dependable inference where cloud offload is not guaranteed.
Field realism
Training signals that reflect messy outdoor conditions instead of idealized lab captures alone.
