## Summary

RobotMCP is aimed at letting general-purpose large models discover, subscribe to, and call an existing ROS/ROS2 system without modifying the robot's source code. The core conflict it addresses is that, in the past, connecting large models to robots often required changing code on the robot side. The original article breaks down RobotMCP's dependency chain and protocol layers.
