Working as a Team, Autonomous Swarming 'Bots Quickly Explore and Map Structures -- Popular Science
A swarm of intelligent, autonomous robots from Georgia Tech may soon be leading the charge into dangerous and uncertain situations, providing valuable mapping intel to first responders, military, or police behind them. A team of researchers there have developed a team of small, rolling robots that can autonomously communicate with one another to quickly build a detailed floor plan map of an entire structure and beam it to nearby humans.
