The possibility of robot overlords? Fortunately, we don’t have to worry about that for a while. For now, scientists and engineers are focused on  improving basic human-robot interaction to perform simple tasks and  better understand and support humans. For Tom Williams, assistant professor of computer science at Colorado School of Mines, that means developing a robot’s working memory to improve robotic communication skills. Williams explains the process of teaching robots to think and act like humans  and the technical, social and moral challenges scientists must contend  with when doing so.
