The arguments for your callback should be const std::shared_ptr<const...>&, so in your case const std_msgs::ms

We are working on the development of a custom differential drive robot using ROS 2 Foxy. Until now, our development was in simulation only and we are now transferring our code to the actual physical robot. I was looking into ros2_control to describe our hardware components and I thought it would be logical to use the diff_drive_controller. So, I have been looking for examples using this approach. However, I have not found any repositories that use ros2_control with the diff_drive_controller. Is anyone aware of physical robots that uses ros2_control with the diff_drive_controller controller in ROS 2 Foxy?

That was not available at the time of writing the question, but that is indeed what we were looking for.

Are there examples of robots using diff_drive_controller in ros2_control? We are working on the development of a custom
