Artificial Intelligence
2
Definition
  • Artificial Intelligence (AI) is the area of
    computer science focusing on creating machines
    that can engage on behaviors that humans consider
    intelligent.
  • A branch of computer science dealing with the
    simulation of intelligent behavior in computers
  • The capability of a machine to imitate
    intelligent human behavior

A.I. Timeline

.
Alan Turing(Turing test,1950)
Norbert Wiener (feedback theory. 1950)
Allen Newell Herbert Simon(First ai program)
1956 John McCarthy regarded as the father of AI
5
John McCarthy
  • 1956 McCarthy coined the term artificial
    intelligence.
  • He defines it as the science and engineering of
    making intelligent machines
  • He also invented the Lisp Language

6
Why Artificial Intelligence??
  • Attempts to understand intelligent entities-learn
    more about ourselves
  • Strives to build intelligent entities as well as
    understand them
  • Computers with human-level intelligence(or
    better) would have a huge impact on our daily
    life
  • Allows less or no human involvement

7
Robotics Technology - Artificial Intelligence
  • The term "artificial intelligence" is defined as
    systems that combine sophisticated hardware and
    software with elaborate databases and
    knowledge-based processing models to demonstrate
    characteristics of effective human decision
    making.
  • The criteria for artificial systems include the
    following
  • 1) functional
  • 2) able to manufacture
  • 3) designable
  • 4) marketable

8
Definition of a 'Robot'
  • According to the Robot Institute of America
    (1979) a robot is"A reprogrammable,
    multifunctional manipulator designed to move
    material, parts, tools, or specialized devices
    through various programmed motions for the
    performance of a variety of tasks".A more
    inspiring definition can be found in Webster.
    According to Webster a robot is"An automatic
    device that performs functions normally ascribed
    to humans or a machine in the form of a human."

First use of the word 'Robotics
  • .
  • First use of the word 'Robot'
  • The use of the word Robot was introduced into his
    play R.U.R. (Rossum's Universal Robots) which
    opened in Prague in January 1921
  • The word 'robotics' was first used in Runaround,
    a short story published in 1942, by Isaac Asimov
    (born Jan. 2, 1920, died Apr. 6, 1992). I, Robot,
    a collection of several of these stories, was
    published in 1950.

Hardware and Software Brains
  • Most robots at present have software brains,
    meaning a computer with a program running
  • A drawback is the limited number of processes
    that can be run on today's computers and the
    single purpose programs running on these
    computers.
  • The programs cannot change themselves.  In other
    words, learning is not possible.

16
Example for hardware brain,Robokoneko the
robocat from Genobyte
  • A brain made out of hardware, will consists of
    several chips that act both independently and as
    a group. 
  • Every chip in itself has a small program.
  • It will process information but also pass it on
    to other chips.
  • The program changes on a continuous basis.
  • The network of chips is quick and will adapt, so
    in contrast with the software brain, it will
    learn.

3D-CAMERA BASED NAVIGATION OF A MOBILE ROBOT IN
AN AGRICULTURALENVIRONMENT
19
Introduction
  • Mapping their environment, recognizing obstacles
    and moving around like human beings is a high
    goal for autonomous mobile robot navigation.
  • The control of a robot with different sensors is
    a current research field with high potential.

20
Components
  • One of the most powerful sensors for control and
    orientation of robots are cameras.
  • In agricultural applications, a mobile robot may
    have the task to navigate through rows of plants.
  • Due to the rough and often slippery ground ,wheel
    encoders are not very helpful in these tasks.

21
  • Here, a range camera, possibly combined with GPS
    and compass devices. This may be a valuable tool
    to generate a 3D map of the robots environment
    and to detect open space to navigate..
  • This holds especially for modern range cameras
    acquiring images at a high temporal resolution
    and getting range information for each pixel
    simultaneously

23
Applications
  • This deliver information on plant structure,
    growth and harvesting.
  • It is used for agricultural operations like for
    spraying , watering or harvesting etc..
  • It is used to estimate plant density and height
