Surrounded by the robots used in his Georgia Institute of Technology laboratory, computer scientist Ronald C. Arkin specializes in behavior-based robots, he's written a textbook with that name. Concerned more with software than hardware, he buys robots from companies and modifies their behavior, increasing their capacities. But outside such places, what Arkin calls "the physical situatedness" of the robot is "absolutely crucial" to its ability to act and react appropriately. Like many of his colleagues, he has been inspired by the way insects and other nonhuman life forms have adapted to their environment. From the book Robo sapiens: Evolution of a New Species, page 153.
