Egocentric Wrist-View Camera + IMU Data for Physical AI
Wrist-mounted camera + synchronized 6-axis IMU. The view a robot's wrist camera actually has — close to the hand, moving with it, object filling the frame.
Free 30-episode sample. Task: folding and organizing cloth. LeRobot v3.0, loads in one line.
Why wrist view
Most egocentric datasets are head-mounted: they watch the hand from the outside, several tens of centimeters away, with the whole room in frame. A robot arm's wrist camera does not see that. It sees the object it is about to touch, filling the frame, moving as the hand moves.
That gap is why head-mounted data transfers poorly to wrist-camera policies. This data is recorded from the wrist.
What it's for
- Pre-training visual encoders for wrist-camera manipulation policies
- Studying hand–object interaction from the manipulator's own viewpoint
- Sim-to-real work that needs the real optical and motion characteristics of a wrist-mounted sensor (rolling shutter, motion blur, fixed focus)
What's inside
| Episodes | 30 (sample) · 300 in the full pack |
| Length | ~19.9 s each (598 frames @ 30 fps) |
| Video | 640×480, 30 fps CFR |
| IMU | LSM6DSO, 6-axis, 104 Hz raw |
| Format | LeRobot v3.0 |
What this is NOT
Read this before downloading.
- No action labels. These are human demonstrations, not robot teleoperation. If your pipeline needs actions, you must derive them (hand pose estimation → retargeting). We have not done this.
- No gripper states, object poses, or language annotations.
- No audio track.
Technical notes
- This sample is a curated selection from the full pack.
- Fixed-focus optics — no autofocus hardware, no focus hunting mid-clip.
- Source video is variable frame rate (~26.4 fps), resampled to 30 fps CFR. Frames are duplicated, never dropped; timing error stays within ±17 ms.
- Video/IMU sync offset was measured by cross-correlation (+548 ms) and applied.
observation.stateis filtered for single-sample sensor read artifacts.imu_raw/keeps the unfiltered 104 Hz values.
How the sample was chosen
Selection is measured, not eyeballed. Each clip is scored and the sample is spread across capture devices:
| weight | measure | |
|---|---|---|
| Sharpness | 55% | variance of Laplacian |
| Exposure | 30% | mean luma near mid-grey, few clipped pixels |
| Motion | 15% | gyro σ — mid-range scores highest; too fast means motion blur |
Spreading across devices matters more than raw score — a sample from a single wearer would not tell you much about the pack.
Load it
from lerobot.datasets.lerobot_dataset import LeRobotDataset
ds = LeRobotDataset("inhandplus/egocentric-wrist-view-camera-IMU-data")
print(ds.meta.info)
print(ds[0]["observation.state"]) # 6-axis IMU at frame time
imu_raw/ holds the untouched 104 Hz CSVs if you need the original rate.
Collection and consent
Recorded by consenting participants in home environments on our own hardware. Clips were reviewed one by one before release; anything with identifiable people, screens, or documents was removed.
Full pack
300 episodes with a commercial, non-exclusive license: https://inhandplus.com/data/task/cloth
Custom collection for a specific manipulation is also available — we can record a new task in about a week.
