A building collapse is almost always terrible, a building collapse of a maternity ward is unthinkable. All of us send our thoughts and prayers to the families of this horrible event.
Although there is no news about any robots being used, robots were first used in disasters for commercial multi-story building collapses– notably the 9/11 World Trade Center. Commercial multi-story buildings present unique challenges for searching because the concrete floors can be densely pancaked in some areas with just inches of space and leave survivable voids in others.
Small robots like the shoe-boxed sized micro VGTV and micro Tracks by Inkutun were used the most at the WTC because they could go into the rubble where a person or dog could not fit and could go further than a camera on a wand. That is still the case, with small robots being used to go between tightly packed layers of rubble at the Berkman Plaza II collapse in Jacksonville (2007) and the Prospect Towers collapse in New Jersey (2010).
Bigger robots such as the IED robots like iRobot Packbot and QinetiQ Talon are often too big for the size of voids in the rubble of a pancake collapse. Really large, “maxi” robots such as the REMOTEC series are not only too big, but the weight poses a problem- as in they are so heavy they could cause a secondary collapse.
If anyone knows of other multi-story building collapses where robots were used, please let me know and a reference and I’ll send a CRASAR patch.
In the meantime, our thoughts and prayers to the families in Mexico…
