Ask your robot questions in plain English with NASA JPL's ROSA

Sim, Easy

ROSA (ROS Agent) from NASA JPL is a LangChain-based assistant for ROS 1 and ROS 2 that lets you inspect and operate a robot with natural-language queries.

ROSA wraps common ROS tools (list nodes, echo topics, check params, call services) as agent tools, so you can ask 'why is my robot not moving?' and it investigates. JPL demoed it on a Spot robot in its Mars Yard. It ships a TurtleSim demo.

Hardware & cost: A laptop with ROS; $0 software plus LLM API usage.

Difficulty: Easy.

Agent install prompt (paste into Claude Code, Cursor or Codex): "Install ROSA from https://github.com/nasa-jpl/rosa (`pip install jpl-rosa` per the README), run the TurtleSim demo, then adapt it to my ROS 2 robot's topics."
