Nice find on the laser.

I've ordered one of each (there is 600mm version)

note mm is the proper Engineering measurement, and cm is a dressmakers measurement.

So whenever you hear how much snow there was, you know they make dress'es [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-46fb01f4-d330-430f-b4a7-cd325fa24a43/contentimage_5F00_938.png:16:16]

You haven't specified what the intended purpose of RoboBobLet is, so I wonder if you actually need to know about anything other than the object in front.

The spec sheet states the field fo view FOV is 25 degrees, so you're likely to pick up objects wider than the bot at reasonable close distances.

The User Manual states there are 4 modes of operation and the API information is here

I imagine the library is using the default range mode, which might explain your results.

Very nice update on your project. The measurements that you have taken do look promising. I agree, that with some filtering (maybe even as simple as median filtering) the data would be quite usable.

Good luck on your project.
