In this talk we give a short introduction to Mozilla rr, a powerful C/C++ debugging tool for Linux, and show how to more effectively debug ROS nodes by republishing messages from rr recordings. Mozilla rr serves as a gdb (GNU debugger) replacement which efficiently records the execution of a process and then provides repeatable deterministic debugging of the recording, enabling a very powerful debugging experience with reverse execution.
