A robot rights movement is taking shape and preparing the world's first ethical guidelines for human/robot relationships.

The "Robot Ethics Charter", which will be unveiled later this year, will insist that humans should not exploit robots and should use them responsibly. It is expected to be a version of the classic three laws of robotics developed by the science fiction author Isaac Asimov. These are that robots must not harm people, and that they must obey orders and protect their own existence unless either conflicts with the first law.

"As robots will have their own internal states such as motivation and emotion, we should not abuse them," argues Professor Jong-Hwan Kim, one of South Korea's top robotics experts. "We will have to treat them in the same way that we take care of pets." A spokesman for the Korean Ministry of Commerce, Industry and Energy said: "The move anticipates that day when robots, particularly intelligent service robots, will become part of daily life."
