Error of a map made by gmapping
I'm trying to run a waffle pi along a path of 60cm width. During the test, I noticed that there is difference between a map made by gmapping and local map made during navigation.
Please see the attached image or link. Black line is made by gmapping and green dotted line is made during navigation. These lines are misaligned and the difference is approximately 20cm.
This phenomenon still happens after update of a Turtlebot3 package (v1.0.0) and a OpenCR firmware (v1.2.0).
Please give me your comment and/or advise.
BRs.
I don't see any error in mapping. I see an offset in localization. Are you running any nodes to locate the robot in the map like AMCL?
Thanks. There is an offset between a map made by gmapping and local map made during navigation. I think this offset has a bad influence for navigation. I'm not sure why the offset occurs and how to minimize the offset. I use AMCL particles for localization. Thank you in advance.
