FEEL-Benchmark

A multimodal egocentric manipulation dataset combining Project Aria smart-glasses recordings (RGB video, eye gaze, hand tracking, IMU) with synchronized Paxini tactile-glove force readings. Released in LeRobot v3.0 format (GR00T path variant).

Overview

26 trials, 700 episodes, ~65.8 min of segmented manipulation, ~2.0 GB
Recording dates: 2026-01-10, 2026-01-21, 2026-01-28, 2026-04-30, 2026-05-06
Camera: Project Aria RGB (1408×1408, 10 fps, H.264)
Tactile: bilateral force totals (action.tactile.left.force_total, action.tactile.right.force_total)
Hand pose: Aria MPS hand tracking (left + right, validity flags, confidence)
Gaze: Aria MPS general eye gaze (yaw/pitch + depth)
Mean episode length: 5.6 s (39,497 frames @ 10 fps)

By object category

Category	Trials	Episodes	Frames	Duration (min)
Bottle	5	237	10,811	18.0
Jelly	6	115	10,232	17.1
Sponge	3	107	6,548	10.9
Water	4	70	4,860	8.1
Wangzai	4	116	4,294	7.2
Coke	2	19	1,512	2.5
Chip	2	36	1,240	2.1

The Bottle category includes a fill-level gradient (Empty_bottle_1, P25_bottle, P50_bottle, P75_bottle, Full_bottle_1) for studying tactile cues of liquid mass and slosh.

Layout

Datasets are grouped by recording session date. Trial names encode the manipulation outcome where relevant (e.g. Chip_intact = potato chip not crushed, Chip_crushed = chip crushed during grasp).

Each *_lerobot/ directory follows LeRobot v3.0:

<trial>_lerobot/
├── meta/
│   ├── info.json          # feature schema, fps, episode counts
│   ├── episodes.jsonl     # per-episode metadata

└── videos/chunk-000/observation.images.main/episode_NNNNNN.mp4

Feature schema

Each row in episode_*.parquet:

Field	dtype	shape	Notes
`index`	int64	(1,)	Global frame index
`episode_index`	int64	(1,)
`frame_index`	int64	(1,)	Per-episode frame index
`timestamp` / `timestamp_ns`	float64/int		Aria device clock
`observation.state`	float32	(7,)	Right-hand pose state
`action`	float32	(2,)	Action vector
`status.hands.valid_right`	bool	(1,)	Hand-tracking validity
`action.tactile.left.force_total`	float32	(1,)	Total force, left glove (N)
`action.tactile.right.force_total`	float32	(1,)	Total force, right glove (N)
`observation.images.main`	video	1408×1408×3	Aria RGB stream

Path format note

Each meta/info.json declares "path_format": "groot". The data_path and video_path templates match standard LeRobot v3.0 (data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet), so the dataset is consumable by both stock LeRobot tooling and NVIDIA Isaac GR00T loaders.

Sensors

Project Aria (RGB, eye-tracking cameras, SLAM cameras, IMUs) with MPS post-processing for gaze + hand tracking
Paxini tactile glove for force feedback (totals exported per side; raw per-taxel data not included in this release)

Loading

from datasets import load_dataset
ds = load_dataset("FeelAuthors/FEEL-Benchmark",
                  data_files="20260506/P25_bottle_lerobot/data/chunk-000/*.parquet")

Or with LeRobot tooling, point a LeRobotDataset at a single trial directory.
