Hello everyone, I'm using navigation stack on a turtlebot-based robot. When launching move_base.launch, I can send 2d nav goal in Rviz and robot cannot find its way to the goal, it just makes small movements. It only reaches it when it is a orientation change but not position one. I looked for errors with roswtf and I get:

ERROR The following nodes should be connected but aren't: * /move_base->/move_base (/move_base/global_costmap/footprint) * /move_base->/move_base (/move_base/local_costmap/footprint)

How can I fix it?

Thank you for your help. There wasn't any problem with topics. Tuning navigation parameters solved my issue.

I suggest you look at this thread: https://github.com/ROBOTIS-GIT/turtle...

Looks it may be caused by either your odometer not reset or sending multiple /cmd_vel messages. So one way to dig deeper is to take a look at rostopic list
