Hi,

Mr. Labbe

Thanks for your advise to the previous problem.These days I am doing the experiments about the 2D navigation only using kinect or Xtion. And I found serious problem which may cause the failure.

As show in the picture 1,I put the turtlebot in the center of house.Then I turned the robot to right in a small angle,but the edge of fake_laser in the rviz move to the left as shown in the picture 2.When I turned robot left,the edge in the rviz turned to right.When I was mapping,the map was always accumulating rotating clockwise.
I guess that it may be the matter of calibration of turtlebot? But there is a error information :Please point me at a wall.

Thanks For the Helps.
