From Wikipedia, the free encyclopedia

The following outline is provided as an overview of and topical guide to robotics:

Robotics is a branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behaviour, and or cognition. Many of today's robots are inspired by nature contributing to the field of bio-inspired robotics.

The word "robot" was introduced to the public by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), published in 1920. The term "robotics" was coined by Isaac Asimov in his 1941 science fiction short-story " Liar!" [1]

Nature of robotics

Robotics can be described as:

Branches of robotics

  • Adaptive control – control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. For example, as an aircraft flies, its mass will slowly decrease as a result of fuel consumption; a control law is needed that adapts itself to such changing conditions.
  • Aerial robotics – development of unmanned aerial vehicles (UAVs), commonly known as drones, aircraft without a human pilot aboard. Their flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle.
  • Android science – interdisciplinary framework for studying human interaction and cognition based on the premise that a very humanlike robot (that is, an android) can elicit human-directed social responses in human beings.
  • Anthrobotics – science of developing and studying robots that are either entirely or in some way human-like.
  • Artificial intelligence – the intelligence of machines and the branch of computer science that aims to create it.
  • Artificial neural networks – a mathematical model inspired by biological neural networks.
  • Autonomous car – an autonomous vehicle capable of fulfilling the human transportation capabilities of a traditional car
  • Autonomous research robotics
  • Bayesian network
  • BEAM robotics – a style of robotics that primarily uses simple analogue circuits instead of a microprocessor in order to produce an unusually simple design (in comparison to traditional mobile robots) that trades flexibility for robustness and efficiency in performing the task for which it was designed.
  • Behavior-based robotics – the branch of robotics that incorporates modular or behavior based AI (BBAI).
  • Bio-inspired robotics – making robots that are inspired by biological systems. Biomimicry and bio-inspired design are sometimes confused. Biomimicry is copying the nature while bio-inspired design is learning from nature and making a mechanism that is simpler and more effective than the system observed in nature.
  • Biomimetic – see Bionics.
  • Biomorphic robotics – a sub-discipline of robotics focused upon emulating the mechanics, sensor systems, computing structures and methodologies used by animals.
  • Bionics – also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
  • Biorobotics – a study of how to make robots that emulate or simulate living biological organisms mechanically or even chemically.
  • Cloud robotics – is a field of robotics that attempts to invoke cloud technologies such as cloud computing, cloud storage, and other Internet technologies centered around the benefits of converged infrastructure and shared services for robotics.

The intention is to allow a user to directly manipulate objects presented to them, using actions that correspond at least loosely to the physical world.
  • Manifold learning
  • Microrobotics – a field of miniature robotics, in particular mobile robots with characteristic dimensions less than 1 mm
  • Motion planning – (a.k.a., the "navigation problem", the "piano mover's problem") is a term used in robotics for the process of detailing a task into discrete motions.

As of June 2011, used for making models, prototype parts, and production-quality parts in relatively small numbers.

  • Speech processing – study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signal.[ clarification needed] Aspects of speech processing includes the acquisition, manipulation, storage, transfer and output of digital speech signals.
  • Support vector machines – supervised learning models with associated learning algorithms that analyze data and recognize patterns, used for classification and regression analysis.
