Stage 10 · ROS 2 & Robot Software Architecture (Fundamentals)

Parts 1–4 complete: why robots need ROS 2 through TF2/QoS/full stack, plus Capstone — Build a ROS 2 6DOF Robot System (pick-and-place architecture validation). Educational ROS 2 communication / architecture simulators only (not a live runtime). Soft-recommend Stages 3/9; hard locks cleared; no payment gating.
