Dear ros player,

I have been experimenting with a live car after taking the ros navigation course and have found a problem that I would like to ask you about.

Every time I finish building a map and prepare to start navigation, I have to manually put the cart back to the starting point of the build, otherwise, the cart cannot accurately estimate its initial position during navigation. So, my question is: Is there any way to eliminate the “manually put the cart back to the starting point” step, after all, it seems a bit redundant.

I look forward to hearing you!

Thank you, Bests.
