Robotics involves the design, manufacture, and application of robots. It is an interdisciplinary field that includes aspects of electronics, mechanics, and software. Some key branches of robotics include android science, which studies human-robot interaction; artificial intelligence, which aims to create machine intelligence; and nanorobotics, which focuses on controlling nanoscale objects. Other branches discussed are robot surgery, laboratory robotics, robot locomotion, telepresence, swarm robotics, and speech processing.
