try adding robot model from rviz.Maybe your rviz is searching for robots in a different topic.

2020-02-17 04:10:11 -0500 marked best answer Follow the straight global plan

Suppose I want to go to point B from A. Global plan initially publishes a straight plan. But whenever, a dynamic obstacle is in the path, DWA will try to drive around the obstacle.

However, I would want to stop for some time and then follow the initial global plan after the obstacle moves away from the plan. I've tried to play with goal_distance_bias, path_distance_bias and other parameters with no success. Is there some straight-forward way to classify dynamic obstacle from the cost map, so I can send zero_velocity from DWA upon detecting one?

Or do I have to write a custom local planner? If yes, could you guys point me towards something to achieve this functionality?

Edit

This question asks a similar question with no answer but some helpful comments.

thank you so much for your help. looks like implementing a PD controller is the best way for me.
