Introduction of robotics- by yantra education

The document discusses the history of robots and the concept of robotic laws. It notes that the word "robot" was first used in a 1921 play and that the first electronic autonomous robots were created by William Grey Walter in 1948. It also explains Isaac Asimov's Three Laws of Robotics, where a robot may not harm humans, must obey orders unless it conflicts with not harming humans, and must protect its own existence as long as it does not conflict with the first two laws. However, the document clarifies that the three laws are not actual laws but were written by Asimov as a fiction writer.
