Hi everyone,
I have some issues while trying to use DWB local planner.
I'm using it with move_base using [this answer]( https://answers.ros.org/question/312524/how-to-use-the-dwb-local-planner/?answer=312527#post-id-312527).
But when I start the navigation, I get these errors:
[ WARN] [1464825005.450915057]: Critic "ObstacleFootprint" failed to prepare
[ERROR] [1464825005.457386149]: computeVelocityCommands exception: No valid trajectories out of 63!
[ERROR] [1464825005.550973984]: Footprint spec is empty, maybe missing call to setFootprint?
I've tried to add in my "base_local_planner_params.yaml" file the "ObstacleFootprint" parameter :
critics:
ObstacleFootprint: [[-0.3, 0.45], [0.97, 0.45], [0.97, -0.45], [-0.3,-0.45]]
But now, my robot goes around in circles with no errors instead of moving towards the destination...
Thanks for your help!
