These commands are called by the frontend to request measurements or send data to the rover. All four are currently partially stubbed — they simulate a 1-second rover response delay and return dummy values, but the actual UDP dispatch logic is ready to be wired in. **`request_coordinates() → (i16, i16)`** Requests the rover's current GPS coordinates. Returns a `(latitude, longitude)` tuple. **`request_weight() → i16`** Requests the weight of a collected rock sample from the rover's load cell. Returns a weight value in grams. **`request_measurement(camera1, x1, y1, camera2, x2, y2) → i16`** Requests a stereo distance measurement. The frontend passes two pixel coordinates (one per camera) and the rover computes the real-world distance to that point. Returns the distance in a unit TBD. **`send_pixel(camera, x, y)`** Sends a single pixel coordinate from the frontend to the rover (e.g. operator clicking on an object in the video feed). Used to direct the rover's attention or arm toward a specific point in the image.
