Awesome stuff at first glance, but - I do have to bud in.
While this does potentially save lives of rescuers, it doesn't necessarily do the same for the people waiting to be rescued. Adding the time that the robot will go in (because after it finds the victims, humans still need to actually get there) might also be adding the time someone under that rubble doesn't have.
Not to mention, while I'm sure the software in this little guy is fantastic, I don't really see a robot having as easy a time navigating and moving through rubble, thus leading to even more time for a robot to find a survivor than a human would (not to mention the possibility for it to get stuck). Maybe it's just my imagination, but I don't think collapsed buildings tend to have a constant flat surface for a robot to move through. What if something requires it to climb/jump over something? Or worse even, move something out of the way?
Perhaps I'm underestimating the robot's hardware, dunno. Wouldn't it be more useful if the rescue crews were given thermal imaging equipment or something similar to help them simply locate the victims visually rather than physically?
