Robotics is an interdisciplinary branch of science that combines elements of cybernetics, electronics, mechanics, automatics, informatics and sensorics. The word „robot' was firstly used in 1921 to describe a humanoid, designed to replace the human at work. Today we are talking about much more precise robotics. It deals with the design, construction, operation, and application of robots. We can differentiate between first, second and third generation robots.
