[Dprglist] Chris N's lidar presentation

[David P. Anderson]

So, I went by hand and looked through all the RBNV videos starting in 
January 2021.  Basically scanning through the videos looking for Chris' 
face, and stopped and listened to what he was saying.   It took hours.   
Still didn't find what I'm looking for.   Maybe if we could put all the 
chat logs in a big data base, where they could be searched, it might be 
easier to find things. Or maybe it's not there.

So did I just imagine this?   Does anyone else remember a presentation 
from Chris where he showed that the Lidar detections were affected by 
the rotation of the robot?   That it made the walls appear to curve and 
bend while the robot was rotating?  And that he developed code to do a 
correction for that warping?   Did I just dream that?  I sure can't find it.

thanks

David
