Radio-controlled outdoor mobile platforms, Micro ATRV and ATRV-2, are produced by Real World Interface, part of iRobot of Somerville, MA. (ATRV stands for All-Terrain Robot Vehicle.) Their main purpose: to carry equipment in and out of areas difficult for human beings to navigate. Looking at the liquid-crystal display for the Micro ATRV, a Real World staffer directs it toward its larger cousin. From the book Robo sapiens: Evolution of a New Species, pages 142-143.
