Dataset Details

Dataset Description

50 GELLO-teleoperated demonstrations (31,960 frames, 30 fps) of one instruction ("Unscrew the cap from the bottle held by the person and place the cap on the table.") on the intern_gello_7dof_robotiq robot schema. The source is a community LeRobot v3.0 repo with two RGB views, two tactile image streams, and force/torque channels. All source episodes are imported, with no success filtering (per the source README).

Uses

Direct Use

Per the source README, training with the InternVLA A-series project (two RGB views mapped; tactile/force channels retained as auxiliary data).

Dataset Structure

Topology. media_type: multimodal, 50 samples, one per episode, 30 fps, 527-1,305 frames (17.6-43.5 s), 31,960 frames total. Samples hold a media_reference to the per-frame parquet data and 4 video streams.

Field	FiftyOne type	Description
`media_reference`	`LeRobotEpisodeReference`	Pointers into `data/` parquet and the 4 video streams
`episode_index`	`IntField`	Episode index (0-49)
`task`	`StringField`	The single task instruction
`tasks`	`ListField(StringField)`	All task strings of the episode
`length`	`IntField`	Frames in the episode
`duration`	`FloatField`	Episode duration in seconds
`robot_type`	`StringField`	`intern_gello_7dof_robotiq`
`fps`	`FloatField`	30

Data behind media_reference (per-frame, from meta/info.json):

Feature	Shape	Description
`observation.state`	(8,)	7 measured joint angles + Robotiq knuckle angle (rad)
`action`	(8,)	7 absolute GELLO joint targets + commanded gripper open fraction (0 closed, 1 open)
`observation.eef_pose`	(6,)	Original six-value pose, no coordinate conversion
`observation.wrench`	(6,)	Force/torque
`observation.wrench_valid`	(6,)	Per-axis validity flags for `observation.wrench`
`observation.gripper_command`	(1,)	Recorded follower gripper command
`source_timestamp`	(1,) float64	Original timestamps
`observation.images.cam_high`, `cam_front`	480x640x3	RGB views (H.264 after re-encode; MJPEG in the source)
`observation.images.tactile_left_aug_diff`, `tactile_right_aug_diff`	700x400x3	Tactile touch images (H.264 after re-encode; MJPEG in the source)

Label types and why. The importer produces episode-level samples with a media_reference; numeric streams (state, action, wrench) are read through the viewer and are not stored as FiftyOne label fields. The source has a single task, so task is constant. No custom fields were added, so the FiftyOne dataset matches what the LeRobot export contains.

Parsing decisions.

All episodes imported from the full repo (3.2 GB).
Metadata repair: meta/tasks.parquet stored the task text as the pandas index (task_index column only). It was rewritten with real task_index and task columns before import.
Video transcode: the source videos are MJPEG in MP4 (remuxed from original JPEG packets, per the source README), which browsers cannot decode, so they did not play in the FiftyOne App. All 200 files (50 episodes x 4 streams) were re-encoded in place with ffmpeg to H.264 (libx264, -crf 18, -g 2, yuv420p; full-range yuvj420p converted to limited range). This is a lossy re-encode of the source pixels. Summed frame counts of cam_high and tactile_left_aug_diff match total_frames in meta/info.json, and video.codec / video.pix_fmt in meta/info.json were updated to h264 / yuv420p. The original MJPEG files are not part of this dataset.

Dataset Creation

Source Data

Data Collection and Processing

The source README describes the original upload, before the H.264 re-encode covered under Parsing decisions. JPEG packets were remuxed into MJPEG MP4 with no resize or re-encode, and every recorded frame is kept. Timestamps are frame_index / 30, not wall-clock resampled; the capture FPS is in the source manifest. Numeric fields were compared to source values, and JPEG bytes were SHA256-checked per stream. Validation records are in meta/validation.json, meta/source_manifest.json and meta/conversion.json.

Annotations

Annotation process

A single natural-language instruction states the intended goal. Per the source README, it does not mean every demonstration succeeded.
