It does not look like the SKURBOT will be at Intergeo 2015.

Just found this one while looking at Zeb1 videos. It's called the ZebRA.

Another impressive piece of work from 3D Laser Mapping :geek:

SKUR had a booth at REAL2016.

FARO also had a presentation of their scanning robot from the FARO Research Labs. Many people viewing the presentation said that it looked very similar to the one that Autodesk did not place into production.

Dug up this old thread to post a practical use of our scanning robot:
RailBot1 (Large).jpg

Our "RailBot" enables us to scan overpasses without the need for a temporary road closure or traffic control, which is less costly and eliminates potential accidents. As you can see in the video most drivers don't even realize it is there.

The only mishap was that the first version was stolen off the side of the road while I was not watching(my fault :oops: ). After getting over the embarrassment, we quickly constructed a new and better version to complete the work. On top of that, we have already heavily modified and improved the current version to tackle the next bridge that has more complicated rails.

Needless to say, I had a ton of fun with this project and am very proud of our team who made it all possible :mrgreen:

How much of an issue is the wind from a truck passing by? I've never scanned a roadway (we do interiors), but I would be so worried about getting weird results from that!

Very cool design, also! Impressive!

Thanks guys!
What would the world of laser scanning be without you, Jonathan?
Thanks Oliver, but honestly I sometimes wonder if we take too many risk. The good thing with taking some risk is that typically learn from small mistakes and improve upon our methods for the next time. I don't want anyone to think this was a perfect operation with perfect results. It certainly was not, but it did get the job done sufficiently.

With regard to wind...Funny that you ask, because I had the same concern while modifying the original robot in preparation for this project. I sought the advice of our structural engineers that have strong background in wind related engineering. While wind from a truck is certainly a concern it is quickly overshadowed by the effect the movement to the bridge can impart. From our experience bridges are like a wet noodle sitting on a vibrating washing machine...everything is not just vibrating, but in motion so the negative effects on scans can be very high. Successful use of scanning in this environment becomes a balancing act between many factors, some within our control and some not. The good news is that most of our "use" of the data occurs at very short ranges reducing the amount of error we have to contend with. At far ranges the data is the not good, but that was our expectation before the robot hit the rails. In the end, I think I can confirm the expectations of our engineers in that wind is not the issue, because the normal motion of the bridge created the larger problem.

I could go on forever about all the other issues we studied during this adventure as there are many more worth noting, but I would burn up a keyboard in the process :lol:
