Robotics is the branch of technology that deals with the design, construction, operation, and application of robots,[1] as well as computer systems for their control, sensory feedback, and information processing. The design of a given robotic system will often incorporate principles of mechanical engineering, electronic engineering, and computer science (particularly artificial intelligence). The study of biological systems often plays a key role in the systems engineering of a project and also forms the field of bionics. The mathematical expression of a biological system may give rise to control algorithms for example, or by observing how a process is handled by nature, for example the bifocal vision system, an analogous system may be formed using electronics.
