The finalists in the DARPA Robotics Challenge faced off this weekend in a series of eight tasks meant to tease out which machines had the right stuff to help humans respond to natural and man-made disasters. Here's a look at how the robots, and their human controllers, fared in the competition's tasks that had to be completed within an hour: drive a utility vehicle, exit the vehicle, open a door, drill a hole in a wall, complete a surprise task, walk over a pile of rubble or clear a path through debris, and walk up a short flight of stairs.
