Quick Overview of

Robotics and

Artificial Intelligence

Intelligent Robotics = Robotics + Artificial

Intelligence

• Textbooks:
  • Luger and Stubbefield, Artificial Intelligence, Structures and Strategies for Complex Problem Solving , Addison Wesley, newest edition
  • Fred G. Martin, Robotic Explorations. A Hands-On Introduction to Engineering. Prentice-Hall, 2001.
• Additional Textbooks:
  • Russell & Norvig, Artificial Intelligence. A Modern Approach, Prentice Hall
  • Wilensky, Common LISPcraft Another very good LISP textbook: Winston & Horn, LISP (Addison-Wesley)
  • Joseph L. Jones, Bruce A. Seiger and Anita Flynn, Mobile Robots. Inspiration to Implementation. Second Edition, A.K. Peters

The Physical World

•The physical world is very demanding, it is:

• inaccessible - sensors are imperfect, only stimuli that are near the agent can be perceived.
• nondeterm inistic - a robot needs to deal with uncertainty
• nonepisodic - effects of an action change over time
• dynam ic - robot needs to decide when to think and when to act immediately
• continuous - states and actions are drawn from a continuum of physical configurations and motions

Robotics

Research area in which AI agents are equipped

with sensors to perceive the world and effectors to

change it

What are the

definitions of

a Robot?

Robot Definitions (cont)

• Russell and Norvig: an active,

artificial agent whose environment is

the physical world.

• Robots differ from Softbots

whose environment consists of

computer systems, databases and

networks.

What is a robot? - more

definitions

• Fictional definition : any system with sensors,

computer and effectors.

• Robots must have a minimum of 4 degrees

of freedom.

• A degree of freedom is the number of

independent movements an object can

perform in a three dimensional space

What is robotics?

Robot a physical system that

autonomously senses the environment

and acts in it.

One more definition

The word robot originated from the

Czech word Robota

• Three laws of robot’s by Science

fiction author Isaac Asimov.

Czech word "robota” means "forced labor.”.
