World-to-Wrist: LeRobot Training Data

This dataset contains the LeRobot action trajectories paired with the public W2-VLA-CoT annotation release. The files are directly expanded into standard LeRobot directories and can be used after download without an additional archive-extraction step.

RoboTwin	50	2,500	549,787
Real world	4	380	220,148
Total	58	4,573	1,043,400

Episode identifiers and frame counts were checked against the matching offline CoT files. The action datasets and CoT annotations are released separately so that text labels can be revised without duplicating videos.
