A multi-task UR3 manipulation dataset in LeRobot v2.1 format, covering
pick-and-place, unstacking, and pushing primitives.

| task_index | description |
|:----------:|:------------|
| 0 | pick up the white glass and put on a brown coaster |
| 1 | Remove cup from nested cups |

## Source datasets
This dataset was assembled by splitting and merging from:
- [`zestcode5/ur3-multiple-task-trimmed-idle`](https://huggingface.co/datasets/zestcode5/ur3-multiple-task-trimmed-idle) - split into per-task subsets; all three tasks above were extracted from it
## Format
- LeRobot v2.1
- Robot: UR3
- One parquet file per episode under `data/chunk-*/`
- One mp4 file per camera per episode under `videos/chunk-*/<camera>/`
- Episode metadata in `meta/episodes.jsonl`, task list in `meta/tasks.jsonl`,
per-episode stats in `meta/episodes_stats.jsonl`
## Loading
```python
from lerobot.common.datasets.lerobot_dataset import LeRobotDataset
ds = LeRobotDataset("zestcode5/ur3-merged-3tasks-v1")
print(ds.num_episodes, ds.num_frames, ds.fps)
sample = ds[0]
```
