A mobile robot has been created that can measure individual distances and roll over to notify them that they are too close together. Although it isn’t quite Robocop, perhaps computerized rule monitoring must begin somewhere. Adarsh Jagan Sathyamoorthy, a Ph.D. student at the University of Maryland, College Park, and associates present a robot they constructed with spatial awareness, enabling it to detect distances between objects or humans in PLOS ONE. Because the robot is movable, it can use the same vision to make its way through a busy environment, alerting those who are too close together to move to a safe distance. The study states that this is done “discreetly, employing a mounted display,” but we wouldn’t bet on no one noticing a robot elbowing its way through a crowd.
