# DexBench — Single-Hand
Single-hand dexterous manipulation demonstrations from **DexBench**, replayed through Isaac Lab and packaged as a LeRobot v2.1 dataset. Each frame ships with third-person + wrist RGB video (256×256 @ 30 fps), proprioception, and the corresponding joint-space action.
## Summary

## Usage
```python
from lerobot.common.datasets.lerobot_dataset import LeRobotDataset
ds = LeRobotDataset("dexbench/single-lerobot")
print(ds.num_episodes, ds.num_frames)
frame = ds[0]
# frame["observation.state"], frame["action"]: torch.Tensor(28,)
# frame["observation.images.third_person"], frame["observation.images.wrist"]: torch.Tensor(3, 256, 256)
# frame["task"]: str (one of the 15 task ids above)
```
## Companion dataset
- **[dexbench/bimanual-lerobot](https://huggingface.co/datasets/dexbench/bimanual-lerobot)** — bimanual subset (746 ep, 56-dim action, additional left/right wrist cameras).
## Source
Replayed from teleop trajectory pickles in the gated [`dexbench/DexBench_dataset`](https://huggingface.co/datasets/dexbench/DexBench_dataset) repo (`teleop_dataset/{rigid, articulation, dexterous, grasping}/...`) using DexBench's `scripts/create_demo_files_sequential.py` (one Isaac Sim env per task, episodes replayed serially within the env, per-episode HDRI / table-texture randomizers disabled for visually stable demos). Then converted with `scripts/convert_to_lerobot.py` (h264 video at CRF 18).
