East Harlem Building Collapse: role of ground robots

It doesn’t appear that small ground rescue robots are being used to assist in the search and rescue of the terrible East Harlem building collapses-if you know of any being used please let me know. We offered our robots to DHS the same day and also New Jersey Task Force 1 and the New Jersey UASI team have small robots that they used in the 2010 Prospect Towers parking garage collapse. All of our thoughts and prayers go out to the families of the 7 victims and missing- as well as to the responders working their way through this disaster.

Ground robots have been used  8 times between 2001 and 2013 for search and rescue in structural collapses- crawling underground in building collapses and mine disasters since the 9/11 World Trade Center collapse.  For building collapses shoeboxed sized robots such as the Inuktun VGTV are a popular choice because that are small and the power/communications tether serves as a belay line for lowering the robot. Ground robot have video cameras but can often be outfitted with a thermal camera. The thermal camera is useful for looking for heat signatures of possible survivors and also smoldering fires or live electrical outlets. A robot typically needs both because thermal radiation produces a fuzzy image, not always good for navigation or for structural assessment. We’ve often velcro-ed a thermal camera to a robot and run a separate tether.

Gas leaks are similar to mine explosions in that there is a worry as to whether the electronics of the robots will set off another explosion. The is referred to as whether the robot is “intrinsically safe.” There are different standards for intrinsically safe depending on the industry so that makes it harder for a robotics company to create a certified explosion proof robot.  I know of only one robot that is certified as intrinsically safe- the Mine Safety and Health Administrations very large “sumo” V2 robot, a variant of the Remotec Wolverine.
