This week, Humbert's team known as MARBLE and听11 other teams are engaging in the first of three DARPA subterranean challenges. They will be sending drones on a mock search and rescue operation down miles of NIOSH Coal Mine steam tunnels in Pittsburgh, part of the Tunnel Circuit Event.听The goal听is to autonomously navigate and map these unknown spaces;听correctly identify DARPA-specified artifacts which include听backpacks, fire extinguishers, and other relevant items; and report artifact听positions and three-dimensional听maps to DARPA during each听deployment.
"It's听a significant challenge due to austere conditions such as mud, rocky terrain and low light,听lack of GPS听and poor device communications," said Humbert. "We are excited to be in second place out of 11 teams after the first two days of deployments."
The competition will continue through the week and will be .听
After the close of the Tunnel Circuit Event, the teams have two more subterranean challenges to go before they are finished. In six months, they will graduate to larger tunnels, such as those that make up the New York subway system. As their听final challenge, they will navigate natural caves which add hazards, including mud, rocks and potential cave-ins. The DARPA Subterranean Challenge is set to end in fall 2021.听
