[SOLVED] Holonomic Robot Not Moving

In addition to what @albertoezquerro, you can check if the publisher is ready before sending data to it, instead of sleeping some random seconds (which does not guarantee that the topic would be ready anyways).

It’s a good idea to include this “publisher ready?” logic in your robotic applications as this will make it more robust.

I will update the ROS Basics notebook with this idea sometime.
