Robotics is a branch of Artificial Intelligence that deals with the design, construction, and operation of robots and is also used to control, and perform sensory feedback with information processing with the help of computer systems. It involves the study of various disciplines such as Nanotechnology, Mechatronics, Bioengineering, Electronics and Computer science. There are certain laws defined by Asimov in defining robotics: Robots should not harm human beings or pose a threat to human beings. They should follow the instructions of human beings without violating rule 1. They should ensure their own protection as long as it doesn't violate rule 1 and 2.
