Simulation, Testing, and Deployment for ROS 2

Source: ros2-copilot-skills catalog

Why This Matters

ROS 2 projects become fragile when build, simulation, and runtime practices are treated as side concerns. Reproducibility is what turns one developer's working laptop into a robot other people can test, review, and improve.

Distilled Takeaways

  • Simulation is most useful when it validates interfaces, timing, TF, and behavior assumptions rather than trying to cosmetically mimic reality.
  • Containers are valuable for repeatability, but only if device access, networking, GUI forwarding, and runtime dependencies are modeled honestly.
  • CI should at least prove that the workspace resolves dependencies, builds, and exercises the most important packages or launch paths.
  • rosbag2 is not just for recording demos. It is one of the best tools for regression testing and offline debugging of perception and navigation behavior.
  • Production startup should be explicit and restartable. If the robot depends on a fragile manual bringup sequence, deployment is not finished.

Practical Value

  • Use simulation to catch TF, topic, and launch integration problems early.
  • Treat Dockerfiles and startup scripts as part of the robot's architecture.
  • Record representative bag files and reuse them as test assets.
  • Prefer boring, well-documented boot flows over clever shell rituals.
