Sometimes rotate in place at the corner
Hello,
My robot is planning path and controlling velocity with move_base.
In many cases, it seems to be working properly.
However, there were times when it suddenly started rotating in place.
This problem does not occur when driving in a straight corridor, but only in 90 degree right angle corner.
Furthermore, after several experiments, I found out that it does not always happen, but sometimes it does and sometimes it does not.
What we know is as follows.
- The place where it occurs is fixed.
- There are times when it does not occur, even in places where it does occur.
- The self-position estimation using amcl shows a plausible result.
- The global path outputs a nice curve to the goal at the end of the corner.
I don't know how to investigate this problem, and I would like to ask for some hints.
Thanks in advance.
