Hi everyone,

I have turtlebot2 and I am using the gampping package to implement SLAM.

When I remote turtlebot to use kinect to scan the environment, I watch the RVIZ to check the map result. But even I just let turtlebot turn around in situ to scan, its location on RVIZ map still jumps from one position to another irregularly.

And finally I get a weird map by overlapping,

Can anyone explan why?

Many thanks
