CRASAR heading home

We’re in the airport now (painfully early in the morning at the Cologne airport, making our way home. The firemen found one of the victims early Sunday morning, the old fashioned way by slow, tedious extrication. As of this morning (Monday), it doesn’t look like the second victim has been found. We were not called out on Sunday but continue to learn more about robots that would be suitable for these conditions. It was a bit embarrassing, the Mayor, Deputy Mayor, and the Chief all shook our hands and were very enthusiastic, despite us doing nothing tangible. Indeed, we are very grateful because we learned so much.

The one photo that “got away” was that of a dozen women with cardboard boxes working in the light rain, picking up documents from the rubble a few meters from the rescuers carefully excavating for victims in the dangerous, unstablized rubble. The women looked like they about to weep from the lost and damage to the Archives, while the fire rescue workers were grim. A sad moment

Looking forward to sleeping on the plane!

Day 1.5 at Cologne

Quick notes before getting some sleep… we have been on standby since going to the site on Friday around noon. City of Cologne and fire department (still fuzzy on naming translations) have been terrific and the Fraunhofer Institute IAIS incredibly supportive.

The Archives buildings was a new, modern multistory commercial building surrounding by multistory residential buildings. When it collapsed into the hole, some of the surrounding buildings were damaged. The one where the two victims are missing is an older (like more than a 100 years old looking) brick building. When brick buildings collapse, the brick crumbles into sand and small pebbles, filling every possible void. Even the ASC couldn’t get in.

The robots were requested this afternoon for the mixed rubble from the houses and the Archives, but it wasn’t a good fit. There were small voids but we couldn’t stand at the face of the rubble due to safety reasons- and the ASC requires us to be right there. The voids big enough for the larger Extreme, which we could operate from the safe location ~10m away, were shallow and thus didn’t require a robot. More notes on how to build better robots.

We’re back on site tomorrow- a huge crane is being brought in to do more excavations and more voids may open. It looks like the old fashioned tedious manual rubble removal is the best technology for this job for now.

Lots of pictures but haven’t gotten permission to release them yet, here’s link to pics from the media and gratuitous coverage 😉
