Unable to navigate robot in rviz - Is Problem regarding move_base, Lattice Planner and Timed Path follower params !?

[chetanchandc]

Hello @marinaKollmitz,
Firstly, thanks for this project.

Concerning the issue, I have implemented this package with respect to the robot (a simple robot with chassis, 2 wheels and a hokuyo link) I have created. Also, I have created a map and world - with some static and dynamic obstacles according to my requirements.

Here the problem is,

1. when I launch rviz w.r.t to the map (playground_new.yaml) that you provided, the robot (which I created) navigates fine.
2. But, when I launch rviz w.r.t to the map (I created), the robot (I created) doesn't start navigating and produces the following errors.

I assume the error is related to Lattice Planner(global_planner_params.yaml) and Timed Path follower (local_planner_params.yaml).

• If yes, would you please let me know where the exact issue arises? I tried to sort out the error but didn't find any solution. Maybe I was missing something!
• If not, would you please let me know what is the exact issue and help with that?

Your answer would help me a lot. Thank you! @marinaKollmitz
