The DARPA Robotics Challenge (DRC) is motivated by disasters such as the Fukushima Daiichi hydrogen explosion, the Deepwater Horizon underwater oil spill, and the Yarnell, Arizona wildfires. DARPA challenges teams of robotics researchers to develop dexterous mobile robots that can move through and within disaster zones and perform useful tasks, with minimal guidance from remote human operators remaining safely out of harm's way.
Each qualifying Track B team must make a humanoid robot (supplied by DARPA) walk over uneven terrain, climb stairs and ladders, enter and drive a small utility vehicle, handle debris and other objects, and use tools. See DARPA's Challenge page for more about the competition goals and rules, the schedule of the "qualifiers" in May 2013, the "virtual" challenge (to be run inside a DARPA-provided simulation) in June 2013, and the real-world "physical" challenges scheduled to occur in December 2013 and December 2014.
Finally, here is DARPA's media fact sheet about the VRC.
