At the 2015 DARPA Robotics Challenge Finals, robots built by teams from around the world are preparing to face off in a competition that tests their ability to assist humans during a simulated natural or manmade disaster.

The competition, funded by the Defense Advanced Research Projects Agency, the military's R&D branch, takes place Friday and Saturday (June 5 and 6) at Fairplex in Pomona, California.

Here are some photos of the bots strutting their stuff during the competition finals and the months leading up to them.
