LabDex: A Hierarchical Benchmark for Dexterous Manipulation in Laboratories

Project Page   |   Paper   |   Code

Overview

LabDex is a large-scale dataset and benchmark for dexterous manipulation in chemistry laboratories, designed to support the training and systematic evaluation of robotic policies across different levels of task complexity.

LabDex provides unified real-world and simulation platforms and organizes laboratory manipulation into three hierarchical levels: Atomic Skills, Compositional Skills, and Long-Horizon Laboratory Workflows. The dataset contains 30+ atomic skills, 10+ compositional skills, 20+ laboratory assets, 8,000+ demonstration episodes, and over 1 million trajectory steps.

Each demonstration includes synchronized multi-view RGB observations, robot proprioceptive states, robot actions, and hierarchical task annotations, providing a standardized foundation for research on laboratory dexterous manipulation and autonomous laboratory robots.
