All, I recently gave a ROS crash course for my lab at Johns Hopkins University, and thought I'd share some of the slides I used. https://jshare.johnshopkins.edu/jbohren1/public_html/ros_cc_1_intro.pdf https://jshare.johnshopkins.edu/jbohren1/public_html/ros_cc_2_patterns.pdf If anyone wants to build on these or extend them, I can give you the LaTeX beamer and figure sources, but right now they're in a private svn. Additionally, is there a good (public) repository for collecting presentations such as these? best, -j -- Jonathan Bohren PhD Student Mechanical Engineering Dept.
