ROS Developers Live-Class #53: ROS Control Introduction - Controllers Types

[@vitalram1985]

Hi, Thanks for your lecture. Apart from PID can we apply sliding mode or adaptive or some kind of model based control. If yes how do we apply it.

[@TheConstruct]

Yes you can apply those kinds of controllers but you will have to build the ROS Controller with that type of controller in the inside. Watch this video to learn how to build your own controller: kzbin.info/www/bejne/bXOvlGRuobR5gNk

Thanks for your reply. I will go through the video.

@@vitalram1985 hey brother , i have the same issue. Can you recommend me some ressources ? i wan't to implement a neural network / backstepping method inside my controller

Please make 1080p video quality, it is difficult to read the content on your screen

Hi! thank you so much for the tutorial. Just a quick question, does ros_control work on SDF model? or do I have to convert it to URDF?

[@jesusdanielolivaresfiguero4752]

Excellent video. I just have one question... Is there a way to do the same for a drone? I already have my own urdf from a drone and now I want to simulate it in Gazebo. But I don't know if it is possible to control it with ROS_Control or if I should use another tool... I hope someone can answer me, that would help me a lot. Thanks!!!

These courses are left half when it comes to going from theory to practice trying to connect a robot created in a laboratory

1:03:42 From your IDE it looks like everything below line 13 is commented out (judging by the color of the code). Perhaps that's the issue?

[@TheConstruct]

No that is not the problem. The code is not commented even if the color indicates so (it is an error of the IDE). The problem is that we did not include a remap in the launch of the joint_state_publisher. You can see the remap properly done in the robot_state_publisher launch line
