Very strange turn behavior with TEB planner

asked 2018-12-04 03:54:47 -0600

I use TEB as the local planner for the robot's navigation. The path of the original TEB planner is very reasonable, as Fig 1 shows.

But as it moves forward, the path becomes very strange. The path first knotted and then became complicated. image description

Clearly the initial path is the best, why will it change?

I'd like to know:

  1. Causes of this problem.
  2. Possible ways to improve.

Can anyone give me some suggestion? Thanks in advance ;-)

Hi,

Were you able to solve the problem? I'm facing similar issues and I don't know what's wrong with my parameters.

Thank you!

Tentative solution: try to increase weight_optimaltime to 10 or more

Hi, Had similar issue, Solved by switching the global_plan_overwrite_orientation parameter to False. Extended answer about why this solution works is mentioned in http://wiki.ros.org/teb_local_planner... under the "Following global plan backwards" headline. Best Regards
