Local costmap overlaps in real robot lab

Course Support ROS Navigation In 5 Days

Hi all!

Do you have any idea why am I seeing this behavior in the real robot lab?

It seems the local costmap overlaps with itself as the robot moves.
This doesn’t happen in the simulation, so I guess the parameters should be well.

Of course, this overlapping produces the costmap to increase up to the point that the robot considers everything to be an obstacle. I don’t know why is this happening.
Thank youu!

Hi, I can see that this happens when you try to send a navigation goal through rviz?

Did this behavior happened as you were localizing the robot? remember that the amcl particles should be somewhat like they are in the picture before sending a goal.

Lastly, do you get any errors from the terminal where you launched your navigation packages? they might be insightful as what is happening if there are some
