LeRobot Studio

LeRobot Studio parses LeRobot datasets in the browser, for checking whether multi-view images, states, and action curves are aligned before export or training. The page offers two data entry points: LeRobot export records completed by the current account, and a local folder or archive.

Prerequisites

Item	Details
Menu entry	Data → LeRobot
Route	/lerobot
Visible roles	Administrator, Project Manager
Related permission	View Export List (view the export list and read export records and download URLs)
Dependencies	The browser supports directory selection, which Chrome and Edge provide; remote data must be directly reachable from the browser and its link must not be expired

Browsing Data

Data Entry Points

Entry	Supported sources	Notes
Export history	LeRobot export records with the Completed status	Selecting a record loads its download URL and opens it in the browser
Local folder	Directory selection	Read a LeRobot dataset from a local directory
Local archive	.zip, .tar, .tar.gz, .tgz	Drag it onto the page or open it through the file picker
Remote address	A reachable LeRobot data address	The page loads the address through the url query parameter

Export history shows only the export records of the current account, and each card shows the dataset name and export time.

Browsing and Playback

Area	Contents
Export history	A paged list of completed export records, 10 per page by default
Browse Local Data	Select a local file or folder, or enter a remote address
Sidebar	The episode list and metadata of the dataset
Playback bar	The episode timeline and playback controls
Back to data selection	Return from the viewer to the data entry page

Constraints and Limits

Item	Value / condition	Notes
Export history scope	Status is Completed	Unfinished exports do not appear in the list
Export history paging	10 per page by default	Adjustable through paging
Export history ownership	Current account only	The list is filtered by account, and an administrator does not see the records of others
Remote address	Must allow cross-origin access and the link must not be expired	Otherwise a message says the remote data cannot be loaded
Directory selection	Depends on the browser capability	When the browser does not support it, a message suggests Chrome or Edge
File format	Archive extension is restricted	Extensions other than .zip, .tar, .tar.gz, and .tgz get an unsupported message

Troubleshooting

Symptom	Possible cause	Resolution	Owner
Export history is empty	The current account has no completed LeRobot export	Create and complete a LeRobot export in Data Export	Project Manager
A message says the remote data cannot be loaded	Cross-origin restriction, a network failure, or an expired link	Open it from a local folder or archive instead	Project Manager
"Exported data cannot be visualized yet" is shown	The export record lacks a usable download URL	Run the export again	Project Manager
"Exported data cannot be visualized yet" is shown with a failed status	The backend failed to read the download URL	Retry later; if it keeps failing, have operations check storage connectivity	Operations, Project Manager
A directory cannot be selected	The browser does not support directory selection	Use Chrome or Edge	Project Manager
"Unsupported file format" is shown	The archive extension is not in the allowed range	Switch to .zip, .tar, .tar.gz, or .tgz	Project Manager
