The term 'mechanical worker' can be summarized as a ROBOT, which is a five-letter word. A ROBOT is an automated machine that is programmed to perform specific tasks, such as manufacturing, assembly, and inspection. Robots are used in many industries, including automotive, aerospace, and medical. They are also used in research and development, as well as in the home. Robots are becoming increasingly sophisticated and are able to perform complex tasks with greater accuracy and speed than humans.
