About ZenO

ZenO Labs builds an egocentric data pipeline for training Physical AI and robot learning policies. Head-mounted GoPro / smartphone footage is processed into LeRobot v2.1 datasets with multiple modalities aligned frame-by-frame:

• 6-DoF head trajectory (visual-inertial SLAM)
• Hand pose — 21 keypoints × 2 hands, with temporal post-processing
• Depth — per-pixel depth maps as video
• Action segments (where annotated)

This release is a free sample — a small preview of what we collect. For larger / customized datasets we offer:

• Longer recordings + more episodes per domain (cooking, assembly, laundry, dishwashing, bartending, …)
• Custom task scenarios on demand
• Higher framerate (60 fps), 4K source, synchronized multi-camera
• Stricter QA + curation tier

Quick use

from lerobot.common.datasets.lerobot_dataset import LeRobotDataset
ds = LeRobotDataset("zeno-labs/sample-gopro-v1")
# Or after local download:
# ds = LeRobotDataset.from_root("./sample-gopro-v1")

Modalities

• head trajectory (6-DoF, x,y,z + quaternion)
• hand pose (21 keypoints × 2 hands)
• depth (per-pixel depth map video)

Hand pose — how to access

Each frame stores 21 MediaPipe keypoints per hand in two separate parquet columns. These are not embedded in the videos — they are numeric data.

Column	Shape	Meaning
observation.hand_pose.left	[21, 3] (float32)	21 keypoints, [x_pixel, y_pixel, z_relative]
observation.hand_pose.right	[21, 3] (float32)	same, right hand

• x_pixel, y_pixel: pixel coordinates in the source video resolution (e.g. 1920×1080 for GoPro Hero 9 wide). Already aligned to observation.images.head frame.
• z_relative: MediaPipe's relative depth (~ −1..+1, not metric). Smaller = closer to camera. Use observation.images.depth if you need metric depth.
• Missing detection → all 63 values are 0.0 (not NaN). Detect with np.allclose(kp, 0) per frame.

Keypoint order follows the standard MediaPipe Hands topology (0=wrist, 4=thumb tip, 8=index tip, 12=middle tip, 16=ring tip, 20=pinky tip).

Quick visualize (per-frame overlay)

import cv2, numpy as np, pyarrow.parquet as pq

t = pq.read_table(
    "https://huggingface.co/datasets/zeno-labs/sample-gopro-v1/resolve/main/data/chunk-000/episode_000000.parquet"
)
df = t.to_pandas()

# pick a frame
i = 100
left  = np.asarray(df["observation.hand_pose.left"].iloc[i],  dtype=np.float32)  # (21, 3)
right = np.asarray(df["observation.hand_pose.right"].iloc[i], dtype=np.float32)

img = cv2.imread("frame_100.png")  # extract the same frame from the head video
for kp_set, color in [(left, (0, 255, 0)), (right, (0, 0, 255))]:
    if np.allclose(kp_set, 0): continue
    for x, y, _z in kp_set:
        cv2.circle(img, (int(x), int(y)), 4, color, -1)
cv2.imwrite("overlay.png", img)

Quick load (LeRobot)

ds = LeRobotDataset("zeno-labs/sample-gopro-v1")
sample = ds[0]
left  = sample["observation.hand_pose.left"]   # tensor [21, 3]
right = sample["observation.hand_pose.right"]

Interactive trajectory viewer

Each episode has an interactive 3D path viewer (head pose + original video + QA metrics). Click a link below — opens directly in your browser.

Episode	Task	View
000000	egocentric manipulation	view trajectory
000001	egocentric manipulation	view trajectory

⚠ Access codes are embedded in these links and may be rotated without prior notice. If a link returns an error, the code has been refreshed — please contact ZenO Labs for new codes.

Limitations

• Hand pose detection rate varies per video (sideways / occluded hands have lower recall).
• Body keypoints are not included — hands only.
• Coordinate frame is ROS REP 103 (X=forward, Y=left, Z=up); remap if your stack uses a different convention.
• Episodes may be re-published; pin to a specific commit SHA for strict reproducibility.

Reproducibility

This dataset may be updated with new commits. To pin a specific snapshot, reference an explicit HF revision (commit SHA):

ds = LeRobotDataset("zeno-labs/sample-gopro-v1", revision="<commit-sha>")
