Robotics – Wikipedia
Robotics is an interdisciplinary branch of engineering and science hat includes mechanical engineering, electrical engineering, information engineering, computer science and others. Robotics deals with the design, construction, operation, and use of robots, as well as computer systems for their control, sensory feedback, and information processing.
These technologies are used to develop machines that can substitute for humans and replicate human actions. Robots can be used in many situations and for lots of purposes like performing home, office activities, etc but today many are used in dangerous environments (including bomb detection and deactivation), manufacturing processes, or where humans cannot survive (e.g. in space, under water, in high heat, and clean up and containment of hazardous materials and radiation). Robots can take on any form but some are made to resemble humans in appearance. This is said to help in the acceptance of a robot in certain duplicative behaviors usually performed by people. Such robots attempt to replicate walking, lifting, speech, cognition, or any other human activity.
