Recently, this initiative has developed a group of self-guiding robots (created by the Georgia Tech team) which interact with each other using inertial sensors. They guide themselves using a camera and laser scanner. In order to interact with each other, the robots use a technique called SLAM (Simultaneous Localization and Mapping) where they can keep track of their own movements to determine their location instead of relying on GPS. The robots work on a team without any kind of hierarchy. The more robots that there are on the team, the faster the data is accrued.
The future of these team-oriented robots includes airborne robots that would be able to see and locate specific buildings and targets.
