# Rosetta

**Rosetta** interfaces ROS 2 robots to robot-learning frameworks like
[LeRobot](https://github.com/huggingface/lerobot).

Record demonstrations to rosbag, declare in a YAML
contract how topics become training frames and how model output becomes
messages again. Rosetta executes that contract identically for training preperation and live inference.

> **Getting started?** The [rosetta_ws](https://github.com/iblnkn/rosetta_ws)
> workspace has ROS 2 Jazzy, Rosetta, and LeRobot installed.
