In the video I move the robot, and the laser readings seem to move along with the robot, when in fact they should be more stationary. I then increase the delay on the /scan topic, and I get a really thick wall, in the direction in which the robot is moving.

Any idea what might cause it? It seems that algorithms like gmapping are producing a pretty decent map.

I did a tf view_frame, and the tf's are all publishing at about 5hz, the robot is defined in a urdf.

Thank you in advance!

Here is the tf_view file, the laser scan comes from veldyne: $C:\fakepath\frames.png$

Could you post the view_frames.py output?

Ive updated the original post with the view frames output

The issue was indeed the odometry was scaled exactly how you said, by half of what the robot moves at.

I had changed the motor controlled/ encoders and did not update the code to properly reflect this.

Thank you
