teb generated trajectory has positive z value

Hi I might be missing some concepts here, but for 2D car like robot why is the output trajectory has pose with non-zero z values? Thank you

Could you update your question and tell which topic you're referring to by saying "output trajectory". And maybe copy rostopic echo message as example?

Are you referring to the visualization markers for the poses?

More of a feature to visualize time. Can be set to 0 to obtain a flat marker topic.
