My Gazebo hospital-auction simulation runs three TurtleBot3s under ROS 2 Humble on Ubuntu 22.04. The nodes launch without crashing, NLP commands publish correctly, yet nothing appears or moves in RViz. RViz throws its usual “Global Options → Fixed Frame does not exist” warning, so the TF tree clearly is not reaching the visualiser; after that the robots ignore the velocity messages as well. I need someone experienced with ROS 2 Humble, TF2, Gazebo / Ignition, and TurtleBot3 launch stacks to jump in, inspect the running graph, and eliminate the missing-frame problem so the three bots become visible and responsive again. I have all launch files, URDFs, and NLP command source ready to share over a screen-share or repo. You’d trace the TF broadcasts, confirm the ...

1. Project Overview(Backend Microservices System (SPRING FRAMEWORK ONLY)) We are developing a large-scale, enterprise-level digital commerce platform on a Java-based microservices architecture (Spring Ecosystem).
