Voxel51/rcs_utn_green_box

Dataset Card for RCS UTN Green Box (FiftyOne)

rcs_utn_green_box is a grouped FiftyOne video dataset of a multi-view robot manipulation task — "pick the green box" — collected with the Robot Control Stack (RCS) ecosystem from the University of Technology Nuremberg. Each episode is a group with one synchronized video per camera, plus dense robot proprioception and action data on every frame.

Installation

If you haven't already, install FiftyOne:

pip install -U fiftyone

Usage

import fiftyone as fo
from fiftyone.utils.huggingface import load_from_hub

dataset = load_from_hub("Voxel51/rcs_utn_green_box")
session = fo.launch_app(dataset)

Dataset Details

Dataset Description

Robot Control Stack (RCS) is a lean, modular ecosystem for robot learning at scale, with a unified interface for simulated and physical robots to facilitate sim-to-real transfer. This dataset captures a single cube-picking task recorded from five camera perspectives, with per-frame joint states, end-effector poses, gripper state, actions, and the tracked cube pose — the kind of multi-view, multi-modal trajectory data used to train and evaluate Vision-Language-Action (VLA) policies.

This FiftyOne version is a grouped video dataset: each episode links the five camera streams so they can be scrubbed together in the App, with robot state and actions rendered as per-frame numeric fields.

FiftyOne Dataset Structure

Dataset name: rcs_utn_green_box

Media type: group

Default group slice: side_wide

Summary

Property	Value
Groups (episodes)	143
Video samples (total)	715
Group slices	side_wide, wrist, side_right, bird_eye, side
Language instruction	pick the green box

Groups and slices

Each episode is one demonstration. The five linked slices are the camera perspectives recorded during that episode:

Slice	Description
side_wide	Wide side view (default slice)
wrist	Wrist-mounted camera
side_right	Right-side view
bird_eye	Top-down bird's-eye view
side	Side view

Videos are encoded as H.264 / yuv420p (30 fps) from the source JPEG frames for in-App playback.

Sample-level fields

Field	Type	Description
episode_id	string	Episode identifier (from the source parquet shard)
camera	string	Camera/slice name for this sample
language_instruction	string	Natural-language task description
intrinsics	list	Camera intrinsics for this view
extrinsics	list	Camera extrinsics for this view

Frame-level fields

Field	Type	Description
step	int	Step index within the episode
timestamp	float	Frame timestamp
reward	float	Per-step reward
success	bool	Success flag
joints	list(float)	Robot joint positions
tquat	list(float)	End-effector pose (translation + quaternion)
xyzrpy	list(float)	End-effector pose (xyz + roll/pitch/yaw)
gripper	float	Gripper state
action_tquat	list(float)	Commanded end-effector action (translation + quaternion)
action_gripper	float	Commanded gripper action
cube_pos_tquat	list(float)	Tracked green-cube pose (translation + quaternion)
