Two suggested ultimate requirements for social robots are the Turing Test to determine the robot's communication skills and Isaac Asimov's Three Laws of Robotics for its behavior. The usefulness to apply these requirements in a real-world application, especially in the case of Asimov's laws, is still disputed and may not be possible at all). However, a consequence of this viewpoint is that a robot that only interacts and communicates with other robots would not be considered to be a social robot: Being social is bound to humans and their society which defines necessary social values, norms and standards. This results in a cultural dependency of social robots since social values, norms and standards differ between cultures.
