2023-10-18 ROSCon Workshop: ros2_control on Steroids
- Summary:
If you already know that the ros2_control framework acts as a Kernel for ROS 2 robotics systems, you are using it but struggling with application complexity, then this workshop is for you. The workshop covers the use of ros2_control in products from various industries and shows solutions for all the little issues when running 24/7.
You will get a practical overview of concepts like controller chaining, hardware modularization, multi-robot architectures and debugging of complex systems. On top of showcasing these functionalities, we expect your involvement in the discussion by bringing your complex application and discussing existing and potentially missing tooling in ros2_control.

2023-09-19 ROSCon Spain Talk: Introduction to ros2_control
Presentation: Introduction to ros2_control
- 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.

2023-07-07 ROS Developers Day 2023: Configure a Mobile Manipulator with ros2_control
TBD add Construct rosject link
- Summary:
In this hands-on presentation, we demonstrate how to set up a mobile manipulator with ros2_control in steps. First, we take a robot mobile base and demonstrate setting up ros2_control simulation for it in the URDF. Once done, a robot arm will be added to the mobile base, turning it into a mobile manipulator robot. The existing ros2_control configuration will be adjusted to accommodate for the new robot parts. Finally, the rosject concludes with a demonstration in Gazebo moving the robot using some off-the-shelf ros2_control controllers.
Attendees will learn
how to prototype a mobile manipulator with URDF and ros2_control
how to configure a gazebo simulation with a given URDF and ros2_control

2022-12 ROS-Industrial Conference 2022
Presentation: ros2_control - Kernel for ROS 2 controlled robots
- Summary:
ros2_control is 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 “kernel” functionality for robots by abstracting the hardware and doing heavy low-level management, for example, hardware lifecycle, communication and access control.

Presentation: A practitioner's guide to ros2_control
- Summary:
ros2_control is 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.
This talk delves deeper into ros2_control, showcasing new features and what they could be used for, such as explicit lifecycle management, chaining controllers, emergency-stop handlers and mock components. Finally, we showcase different usages of ros2_control on openly accessible examples.

Presentation: What is new in the best (and only) control framework for ROS2 - ros2_control
- Summary:
ros2_control is a hardware-agnostic control framework with a focus on both real-time performance and sharing of controllers. The framework has become one of the main utilities for abstracting hardware and low-level control for 3rd party solutions like MoveIt2 and Nav2 systems.
The presentation provides practical tips to use ros2_control, from creating a robot description, writing hardware drivers to configuring standard controllers. Some hot-new features, like controller chaining, will be shown. Furthermore, you will get introduced to concepts like modular reuse of hardware drivers, multi-robot architectures and parameters injection for controllers.

Presentation: ros2_control - The future of ros_control
- Summary:
ros2_control is a robot-agnostic control framework with a focus on both real-time performance and sharing of controllers. The framework offers controller lifecycle and hardware resource management, as well as abstractions on hardware interfaces.
Controllers expose ROS interfaces for 3rd party solutions to robotics problems like manipulation path planning (moveit2) and autonomous navigation (nav2). The modular design makes it ideal for both research and industrial use. A robot made up of a mobile base and an arm that supports ros2_control needs no extra code, only a few controller configuration files and it is ready to go.

Presentation: Making a robot ROS 2 powered - a case study using the UR manipulators
- Summary:
With the release of ros2_control and MoveIt 2, ROS 2 Foxy finally has all the “ingredients” needed to power a robot with similar features as in ROS 1. We present the driver for Universal Robot’s manipulators as a real-world example of how robots can be run using ROS 2. We show how to realize multi-interface support for position and velocity commands in the driver and how to support scaling controllers while respecting factors set on the teach pendant. Finally, we show how this real-world example influences development of ros2_control to support non-joint related inputs and outputs in its real-time control loop.

Presentation: Online Trajectory Generation and Admittance Control in ROS2
- Summary:
One of the top reasons to upgrade from ROS1 to ROS2 is better suitability for realtime tasks. We discuss the development of a new ROS2 controller to handle realtime contact tasks such as tool insertion with industrial robots. The admittance controller handles trajectories and single-waypoint streaming commands, making it compatible with MoveIt and many teleoperation frameworks. Part of the work involved ensuring kinematic limits (position/velocity/acceleration/jerk) are obeyed while limiting interaction forces with the environment. Finally, we give practical recommendations and examples of the admittance controller. A live demo will be shown at our booth.

2021-10-07 Weekly Robotics Meetup #13
Meetup presentation: Getting started with ros2_control
- Summary:
ros2_control is a robot-agnostic control framework with a focus on both real-time performance and sharing of controllers. The framework offers controller lifecycle and hardware-resource management, as well as abstractions on hardware interfaces.
Controllers expose ROS interfaces for 3rd party solutions to robotics problems like manipulation path planning (moveit2) and autonomous navigation (the ROS2 navigation stack). Hardware components on the other side provide a unified interface for robotic hardware, enabling standardized life-cycle and access management. The modular design makes ros2_control ideal for both research and industrial use. For example, a robot made up of a mobile base and an arm that supports ros2_control needs no extra code, only a few controller configuration files, and it is ready to go.
In this talk, we will discuss concepts of ros2_control framework compared to ros(1)_control framework and show examples of their use in the wild.

Presentation: Getting started with ros2_control
- Summary:
The presentation gives a quick overview on the basic concepts and some simple implementation examples. We show implementing a simple Hardware Abstraction Layer (aka SystemComponent) and a forwarding controller. Once done, we also look into modifying the controller with the example goal of changing the type of the command topic.
