Hi there!

I am trying to let a robot with omni-directional drive (ridgeback) follow a global path generated with global_planner::GlobalPlanner from navigation package. I am using the ridgeback_gazebo simulation for this. The local planner is dwa_local_planner::DWAPlannerROS. I am using standard parameters for both global and local planners as well as the cost maps from ridgeback package (see here), but also tried to modify multiple parameters. However, I get the strange behavior that sometimes the robot stops even if no object is near and turns on point. This can be seen here at 0:20 : Video.

I would love to know why this occurs. I also tried TrajectoryPlannerROS and set the weights such that following the global path has extremely high priority, but unfortunately with the same behavior.

Platform: Ubuntu16.04 with ROS Kinetic Versions: Everything installed from apt in the last 7 days

Video description: This is a recorded map from the ridgeback_gazebo standard simulation environment, yellow displays the global path, blue the local path and the local costmap can be seen. I am using amcl / map_server for localization. Thank you for your time!
