Exploring
ROS 2
Robot middleware. Exploring: no public ROS 2 workspace in this Lab.
Simple explanation
ROS 2 is the software bus of many robots (nodes, topics, services). Reading a tutorial is not a deployment.
Technical explanation
DDS, lifecycle nodes, tf2, simulation (Gazebo / Isaac). Later link to VLA / simulation.
Evidence
None. This node keeps a Physical AI intention from being mistaken for a robot stack.
