UNIT I BASIC CONCEPTS  

Definition and origin of robotics – different types of robotics – various generations of robots – degrees of freedom – Asimov’s laws of robotics – dynamic stabilization of robots.

Robotics

Robotics is a form of industrial automation.

Robotics is the science of designing and building robots suitable for real-life applications in automated manufacturing and non manufacturing environment.

Industrial automation

In reference with the industrial knowledge,Automation is nothing

but the “technology”that is concerned with the use of mechanical,

electronic and computer based systems in the operation

and control of production.

The three basic classification of industrial automation are:

(i) Fixed automation

(ii) Programmable automation

(iii) Flexible automation.

1.2. INDUSTRIAL ROBOT:

  • An industrial robot is a re-programmable multi-functional manipulator designed to move materials, parts, tools or special devices through variable programmed motions for the performance of various different task in their operation.


  • An industrial robot is a general purpose, programmable machine which possesses certain human like characteristics.



ROBOT:
  • The term ‘robot’ was derived from the English translation of a fantasy play written in Czechoslovakia around 1920.

  • ‘Robota’ means either a slave or mechanical item that would help its master.

  • A robot carries out the task done by a human being.

Various Definitions of Robot:

  • A Robotics Industries Association in November, 1979 defined Robot as “a re-programmable multi-functional manipulator designed to move material, parts, tools or specialized device through various programmed motions for the performance of a variety of tasks”.

  • This definition indicates that a robot is a manipulator that is re-programmable and multi-functional.

  • It can perform various activities, sometimes it can use end effectors to move raw materials for further processing.

  • Webster’s defined robot as “an automatic device that performs functions ordinarily ascribed to human beings”.

LAWS OF ROBOTICS:


Law 1:

A robot may not injure a human being, or, through inaction, allow a human to be harmed.

Law 2:

A robot must obey orders given by humans except when they conflicts with the first law.

Law 3:

A robot must protect its own existence unless that conflicts with the first or second law.

  • A system is nothing but the integration of whole of parts or subsystems.
  • A robot is a system as it combines many sub-systems that interact among themselves as well as with the environment in which the robot works.
  • A robot anatomy is concerned with the physical construction of the body, arm, and wrist of the machine.
