Robotics is an interdisciplinary branch of engineering and science
that includes mechanical engineering, electronic 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, 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 replicative behaviors usually performed by people. Such robots
attempt to replicate walking, lifting, speech, cognition, or any other human
activity. Many of today's robots are inspired by nature, contributing to the
field of bio-inspired robotics.
