Autonomous Robots Prepped For Cave Search And Rescue Mission

After practicing in a former limestone mine and an abandoned hospital outside of Pittsburgh, a fleet of robots from Carnegie Mellon University is headed to Kentucky for the final test of the ability to autonomously navigate an uncertain, underground course.

The challenge: Collect as many objects as possible in one hour while navigating a cave in Louisville, Ky.

The goal: Create autonomous robots to help with search and rescue missions for military and first responders.

The kicker: There’s only one operator and a fleet that could include a dozen robots, so the machines must be able to move and make decisions on their own.

It’s hard enough to make autonomous robots useful above ground. This CMU team is trying to do it in the depths below.

“At the heart of this challenge, it’s really a problem of exploration,” said Sebastian Scherer, the colead for CMU’s team and an associate research professor at the Robotics Institute. “You’re going into an environment that you’ve never been into, so with that comes a lot of uncertainty and the robot needs to be able to decide what do I do when I face uncertainty.”

The researchers and students at CMU partnered with Oregon State University to create their fleet, dubbed Team Explorer.
