+
+Summary:
+  This presentation aims to introduce the audience to the ros2_control framework, a hardware-agnostic control framework focusing on the modular composition of control systems for robots, sharing of controllers as well as real-time performance. The framework provides controller-lifecycle and hardware management on top of abstractions of real or virtual hardware interfaces. The talk explains different modules within the ros2_control ecosystem, such as hardware interfaces, controllers, controller managers, and how they interact with each other.
