subterranean

In a dark, wet and rocky research coal mine in western Pennsylvania, teams from around the globe put their robotic systems to the test in the Defense Advanced Research Projects Agency’s, or DARPA’s, latest contest. The agency designed the Subterranean Challenge, also known as the SubT Challenge, to spur the advancement of technologies that work well underground, including autonomous and other robotic systems, which could benefit first responders and the military, explained Timothy Chung, program manager, Tactical Technology Office, DARPA, to the media in attendance at the event.
