A social robot is a robot that interacts and communicates with humans or other autonomous physical agents by following'social behaviors and rules attached to its role. This book provides a socially involved, yet sober, insight into the questions of robotics. Which robot technologies are coming? What are they capable of? Which ethical and regulatory questions will they consequently raise? The authors examine the social significance of the new generation of robots in five areas: home robot, care robot, auto robot, police robot, and military robot.
