DARPA Subterranean Challenge: Urban Circuit Preview

The Urban Circuit of the DARPA Subterranean Challenge is the second of four robotics competitions that send teams of state-of-the-art robots into challenging underground environments in an attempt to seek out artifacts while creating detailed maps. Last August, the robots explored a man-made tunnel system in the NIOSH research mine near Pittsburgh, Pennsylvania. And starting this Thursday, the teams will be taking on the urban underground, at Satsop Business Park in Elma, Wash.
