This document discusses human robot interaction (HRI) and provides examples of modern robots. It begins by defining HRI and outlining Isaac Asimov's three laws of robotics, which aim to ensure safe interaction between humans and robots. Examples are then given of three robots: Valkyrie, a humanoid robot designed by NASA; Schaft, a robot that won a DARPA competition; and CHIMP, a tracked mobile robot. The document concludes by asking what future robots may look like.
