I’m doing the micro project. I want to start from the pi_robot_v2.urdf, I have created the launch files for the controllers, spawn the Gazebo model, but it shows the following error:
[WARN] [1637960432.007185, 0.000000]: Controller Spawner couldn’t find the expected controller_manager ROS interface.
In addition, it does not show the Gazebo model.
Please could you help me?
