Doing Real-Time with ROS 2:
Capabilities and Challenges
Overview
Deterministic behavior is crucial for many aspects of successful robot systems; from industrial welding robots following an exact path deterministically for consistent production quality, to safety-critical robots deployed in missions such as drone package delivery, autonomous driving or warehouse conveyance. This workshop will introduce participants to the on-going work to make ROS 2 usable as a foundation for soft, firm and hard real-time robot systems. Participants will learn what the current capabilities are of ROS 2 for real-time robotics, what still remains to be done, and how they can contribute to making ROS 2 usable in these applications.

Work that remains to be done before ROS 2 is usable in a real-time robot system, as well as work that is non-essential but would improve the usefulness of ROS 2 in such systems.
