Interacting with a fleet of robots is getting much easier these days. Georgia Institute of Technology researchers have created a system that allows a single person to control a group of robots with the swipe of a finger. They used a tablet and a red beam of light to accomplish this. Robots roll toward the illumination and communicate with each other to decide how to cover the lit area.
As the person drags the light across the floor with a swipe on the tablet, the robots follow. Using two fingers in different locations on the tablet leads to the robots splitting into teams. Pretty cool, isn’t it?
