One thousand feet underground, a four-legged creature scavenges through tunnels in pitch darkness. With vision that cuts through the blackness, it explores a spider web of paths, remembering its every step and navigating with precision. The sound of its movements echos eerily off the walls; it is an autonomous rescue robot. Initially designed to find survivors in collapsed mines, caves, and damaged buildings, that is only part of what it can do. Created by a team of University of Colorado Boulder researchers and students in 2021. Two years later, they are pushing the technology even further. The team developed an advanced system of sensors and algorithms to allow the robots to function on their own; once given an assignment, they make autonomous decisions on how to best complete it. The team is also integrating new sensors to make the robots more effective in challenging environments. The robots excel in clear conditions but struggle with visual obstacles like dust, fog, and snow.
