Introduction to the Robot Operating System (ROS) Middleware
summary
Overview of ROS installation and hands‑on build: Debian/Ubuntu install targets Lunar Loggerhead (May 2017) with ARM support for Raspberry Pi, set up via apt repos and sourcing setup.bash. Uses catkin_make to create a workspace (initial build prints ~25–30 lines), demonstrates a 10 Hz talker/listener pub/sub example and record/playback via bags, models a tank‑drive Raspberry Pi robot with LiDAR and Alexa in gazebo and RViz, and notes the ROS master is a single point of failure.
