This presentation discusses the building of a task-driven, message-synchronized execution abstraction layer on top of ROS’s message passing, aiming to mimic a deterministic system while continuing to use a non real time operating system. We discuss the overall structure of the framework, as well as the details of various capture and synchronization policies, and the profiling and diagnostics of task executions. We further discuss methods for using simulators and bagfiles in conjunction with the synchronization framework for repeatable testing and issue reproduction.
