## Summary

This tutorial explains how to build a robot simulation environment with ROS2 and Gazebo, covering URDF modeling, lidar and differential drive plugin configuration, SDF world editing, and sensor noise injection. It highlights common pitfalls such as use_sim_time, the TF tree, and physical parameter calibration, and presents advanced directions including multi-robot simulation, hardware-in-the-loop, and CI automated testing, helping developers validate algorithms such as Nav2 and SLAM in simulation before migrating to real hardware.
