# China’s Embodied Dataset Bet — Open Trajectories for Physical AI

> Chinese research/industry consortium open-sourced a large multimodal embodied dataset (March coverage): 10M+ trajectories, multi-morphology robots, vision/force/audio/proprioception, CN/EN language annotations — claimed among world’s largest open physical-interaction sets. Strategic open-data move; ‘largest’ is claimant language.

Sim-to-real still dies on missing real trajectories. China’s proprietary play: **open a national-scale embodied multimodal corpus** so physical AI training is not only a closed lab asset — and claim global “largest” status while doing it.

A consortium of Chinese research institutions and companies released what they **claim** is among the world’s largest open multimodal datasets focused on physical interaction and robotics. Reported contents: **over 10 million** trajectories; multiple robot morphologies; synchronized **vision, touch/force, audio, proprioception**; natural language annotations in **Chinese and English**. Access via national research platforms and open-source communities; builds on standardized embodied-data efforts (coverage cites PaXini and related national programs around early 2026). Pandaily and industry reports carried the March window.

## Claims vs checks

Release existence and scale claims are **consortium / secondary press** (Pandaily, industry). “World’s largest” is **claimant** — not independently measured here against Open X-Embodiment-class corpora. Annotation quality and license terms need primary dataset cards.

## Limits

- Trajectory count ≠ task diversity or success-rate labels.
- Export/access controls may limit non-China researchers in practice.
- Embodied progress still needs hardware and policy, not only data.
