@yuval.shlomo,

Welcome to the Community!

Please check for the following:

  • Did you create a publisher for the cmd_vel topic?
  • Also, did you take off the drone before trying to move it? You need to create a separate publisher for this as well.
  • Please also take note that publishing to a topic once might not work. See this post on how to publish once and get it to work.
