🦾 LeLab
The official graphical interface for LeRobot.
LeLab is a web app that puts the full LeRobot workflow — calibrate, teleoperate, record, train, replay — into a single browser UI. Plug in your arm, open the app, and go. No CLI gymnastics, no keyboard prompts.
🤗 A web-native front door to LeRobot, designed so newcomers can get from "unboxing" to "training their first policy" in minutes.
🤗 Install and run everything with a single command.
Quick Start
Grab the one-liner from the LeLab Space — it installs and runs LeLab + LeRobot in a single command.
A page will automatically open in your browser and you are ready to go.
