# LeRobot Example Datasets
# LeRobot example datasets

This directory contains minimal usage examples for recording, visualizing and
analyzing LeRobot datasets.
Minimal examples for recording, visualizing and analyzing
[LeRobot](https://github.com/huggingface/lerobot) datasets from Isaac Teleop.

## Prerequisite

```
pip install lerobot
```bash
uv pip install -e ./examples/lerobot # add [viz] for the rerun viewer
python -m isaaccapture_examples.lerobot.record
```

## Examples

- **record.py**
Record a dataset in the LeRobot format from live human data. Currently it only
captures head and hands position for demonstrations purpose.
| Module | What it does |
| --- | --- |
| `record` | Records a LeRobot-format dataset from live human data — head and hand positions only, for demonstration |
| `visualize` | Plots a dataset with [rerun](https://rerun.io) (needs the `viz` extra) |
| `analyze` | Parses and summarizes a recorded dataset |

Note: the record.py script always create a new dataset. You must remove
existing one before running it again:
Datasets are written to `./local_datasets/` relative to where you run the
command, and the other two modules read from the same place. `record` always
creates a new dataset, so remove an old one before re-running:

```bash
rm -rf local_datasets
```

- **visualize.py**
A basic rerun visualizer to plot out the dataset.
```bash
rm -rf local_datasets
```

- **analyze.py**
A quick sample to parse and analyze the LeRobot dataset.
> The SO-101 teleoperation example referenced from the Isaac Teleop docs lives
> in the [LeRobot repository](https://github.com/huggingface/lerobot) under
> `examples/isaac_teleop_to_so101/`, not here.

Select the timestamped dataset in visualize.py.

record.py writes each dataset to local_datasets/teleop_tracking_<timestamp>, but visualize.py always passes local_datasets/teleop_tracking as root and has no fallback or selection logic. It cannot load a newly recorded local dataset. Reuse analyze.py’s timestamped-directory selection, or remove the timestamp from the recording path.

In `@examples/lerobot/python/isaacteleop_examples/lerobot/record.py` at line 74,
Update visualize.py’s dataset-root selection to locate and use the timestamped
local dataset directories produced by record.py, reusing analyze.py’s existing
selection logic where applicable; ensure newly recorded datasets are loadable
without changing the recording path.
