SATSOP, Wash. — Amid the ruins of what was meant to be a nuclear power plant, a robot catches a whiff of carbon dioxide — and hundreds of feet away, its master perks up his ears.
“I think I’ve got gas sensing,” Fletcher Talbot, the designated human operator for Team CSIRO Data61 in DARPA’s Subterranean Challenge, told teammates who were bunkered with him in the bowels of the Satsop nuclear reactor site near Elma.
Moments after Talbot fed the coordinates into a computer, a point appeared on the video scoreboard mounted on a wall of the bunker. “Hey, nice,” one member of the team said, and the whole squad broke into a short burst of applause.
Then it was back to the hunt.
The robot’s discovery marked one small step in the Subterranean Challenge, a multimillion-dollar competition aimed at promoting the development of autonomous robots to seek out and identify victims amid the rubble of an urban disaster area, or hazards hidden in the alleys of a hostile cityscape.
