ROBOTS

A robot is a machine designed to execute one or more tasks automatically with speed and precision. There are as many different types of robots as there are tasks for them to perform. 

To understand it more fully or in a simpler way;A mechanical device that sometimes resembles a human and is capable of performing a variety of often complex human tasks on command or by being programmed in advance. A machine or device that operates automatically or by remote control.

The word robotics first appeared in Isaac Asimov’s science-fiction story Runaround (1942). Along with Asimov’s later robot stories, it set a new standard of plausibility about the likely difficulty of developing intelligent robots and the technical and social problems that might result. Runaround also contained Asimov’s famous Three Laws of Robotics: 

• 1. A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
• 2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
• 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
  
  

  Robots have replaced humans^, in performing repetitive and dangerous tasks which humans prefer not to do, or are unable to do because of size limitations, or which take place in extreme environments such as outer space or the bottom of the sea. There are concerns about the increasing use of robots and their role in society. Robots are blamed for rising technological unemployment as they replace workers in increasing numbers of functions.The use of robots in military combat raises ethical concerns. The possibilities of robot autonomy and potential repercussions have been addressed in fiction and may be a realistic concern in the future.

  
  

  ROBOTICS
  Robotics are Design, construction, and use of machines (robots) to perform tasks done traditionally by human beings.
  Robots are widely used in such industries as automobile manufacture to perform simple repetitive tasks, and in industries where work must be performed in environments hazardous to humans. Many aspects of robotics involve artificial intelligence; robots may be equipped with the equivalent of human senses such as vision, touch, and the ability to sense temperature. Some are even capable of simple decision making, and current robotics research is geared toward devising robots with a degree of self-sufficiency that will permit mobility and decision-making in an unstructured environment. Today’s industrial robots do not resemble human beings; a robot in human form is called an android.
  Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings.
