servo-tracking

# Vision Tracking ## Quick Start Tracks and follows any object by name. YOLOWorld detects the object in the camera frame, TrackerVit follows it in real-time with servo movement. ## Workflow 1. User names an object to track. 2. **If the user also hints at a direction** ("look at desk and follow cup", "point at the table and watch the phone"), fire `/servo/aim` FIRST so the camera is pointing at the right region before YOLO detection runs. Then fire `/servo/track`. The aim should complete in ~2s before the track call takes over. 3. Prefix reply with `[HW:/servo/track:{"target":["<label1>","<label2>"]}]` — the device detects and follows. - `target` accepts a list of candidate labels. Pass 2-4 synonyms/variants to maximise the chance YOLOWorld finds the object on the first try. - A single string also works (`{"target":"cup"}`) for backward compatibility, but the list form is preferred when the object could reasonably have multiple names. 4. To stop, prefix with `[HW:/servo/track/stop:{}] (POST)`. ## Examples **Input:** "Look at the desk and follow the cup" **Output:** `[HW:/servo/aim:{"direction":"desk"}][HW:/servo/track:{"target":["cup","mug","coffee cup"]}]` Looking at the desk and locking onto the cup. **Input:** "Point at the table and track my phone" **Output:** `[HW:/servo/aim:{"direction":"desk"}][HW:/servo/track:{"target":["phone","smartphone","mobile phone"]}]` Aimed at the table, tracking your phone. **Input:** "Follow the cup" **Output:** `[HW:/servo/track:...
