Legions of lunar landers, and why we make robots that look like people

Staff Writer Paul Voosen talks with host Sarah Crespi about plans for NASA’s first visit to the Moon in 50 years—and the quick succession of missions that will likely follow.  Next, Eileen Roesler, an engineering psychologist at the Technical University of Berlin, discusses the benefits of making robots that look and act like people—it’s not always as helpful as you would think.  This week’s episode was produced with help from Podigy.
