guyuehome/ros2_21_tutorials

The project is a high-quality educational resource associated with the GuyueHome robotics ecosystem, a prominent player in the Chinese robotics education market. With nearly 400 stars and 122 forks, it has served as a standard entry point for developers. However, from a competitive intelligence standpoint, it lacks a technical moat. The repository contains standard implementations of ROS 2 patterns (Pub/Sub, Services, Actions) which are publicly documented in official Open Robotics manuals. The primary threat is not from frontier labs building competing tutorials, but from the rapid advancement of LLMs (ChatGPT-4o, Claude 3.5 Sonnet) and coding assistants like GitHub Copilot. These tools can now generate specific, context-aware ROS 2 boilerplate and debug node logic on the fly, rendering static tutorial repositories increasingly obsolete for intermediate and advanced developers. Furthermore, as ROS 2 evolves through its release cycles (from Foxy/Humble to Jazzy), static tutorials without high velocity risk becoming deprecated due to breaking changes in build dependencies or API signatures. The 0.0 velocity indicates this repository is currently in a maintenance or dormant state, further increasing the risk of bit rot.
