Last Saturday, we spent the day scanning a small railroad bridge located in “Robot City.”  Robot City is located on the site of the LTV Cokeworks, and is in the process of being redeveloped as prime real estate close to downtown. In the meantime, we use it for robot testing.

The robot city bridge is a good test case for us because it is a relatively small bridge but with interesting geometry.

The day started out good, and we set up fiducials on various points around the environment.  We had some paper targets as well as some professional and home made spherical targets.

We used our Faro scanner to scan from various positions under, around, and even on top of the bridge.  In parallel, we scanned parts of the bridge with the ARIA UAV. That part went much faster, but the data will be lower resolution.

After lunch, it began to rain, and we had to bring in the equipment. We were able to get in a few more scans between rainstorms, but it was a challenge.  At the end of the day, we found that our car battery died! We all sat in the car in the storm while we waited for a jump.
