Imagine a warehouse floor with rows upon rows of square, man-high racks. Now add 200 autonomous robots, scurrying about, picking up racks and moving them around. That's Kiva Systems, reinventing the warehouse so workers won't come to find goods but goods move to find workers. In the latest Robots podcast interview Raffaello D'Andrea, professor at ETH Zurich and founding member of Kiva Systems, takes us behind the scenes of the Kiva robots. Also in this episode: the second quarter of sci-fi author Jack Graham's "Selkies".
