Once calibration is complete, the system will save the calibration to `/Users/your_username/.cache/huggingface/lerobot/calibration/teleoperators/homunculus_glove/red.json`

#### Visualizing Teleoperator Glove
|
||||
|
||||
After calibration, you can visualize the glove movements in real-time. Open the visualizer by navigating to the visualizer directory and opening the HTML file in your browser:
|
||||
|
||||
```bash
|
||||
open examples/hopejr/visualizer/index.html
|
||||
```
