Title: The World of Androids


1
The World of Androids
  • Presented by
  • Shipra Gupta
  • CSC 650

2
Overview
  • Brief introduction of robots their history
  • Advent of androids
  • Issues and challenges
  • Dealing with challenges
  • Approach of their working
  • Detailed examples
  • Some in-process android projects
  • Popular androids and main industries using them
  • Advantages of androids
  • Future and fears of androids

3
What is a Robot?
  • Common Definition A programmable machine that
    imitates the
  • actions or appearance of an intelligent creature
    usually a human.
  • Should be able to do two things
  • Get information from its surroundings
  • Do something physical
  • Modern industrial robots have been around for
    less than 50 years.
  • First programmable Robot was developed in 1954
    by George Devol
  • - Coined the name of the first Robot
    Company, Unimation.
  • Since then they are
  • - Painting cars at Ford plants
  • - Assembling Milano cookies for Pepperidge
    Farms
  • - Driving trains in Paris
  • - Defusing bombs in Northern Ireland

4
The RUR Robot
  • Robot comes from the Czech word robota
  • Described fabricated workers in a fictional
    1920s play called Rossums Universal Robots
  • During early studies of literature and fiction,
    Asimov stated 3 laws
  • A robot may not injure a human being, or,
    through inaction, allow a
  • human being to come to harm
  • A robot must obey the orders given it by human
    beings except where
  • such orders would conflict with the First Law
  • A robot must protect its own existence as long
    as such protection does
  • not conflict with the First or Second Law
  • (A zeroth law was added later as an extension of
    Law 1)

5
The World of Androids
  • Basis of Androids
  • High demand to do tedious and dangerous tasks
  • Advent of faster and cheaper processors
  • Make robots move and "think" to look more like
    humans
  • Psycological factors
  • These facts have gave birth to ANDROIDS.
  • Definition An android is an anthropomorphic
    robot
  • - Looks like a human
  • - Known as "humanoids"

6
The World of Androids - contd.
First Android WABOT-1 by Waseda University (1973)
  • Had a limb control system, a vision system, and
    a conversation system.
  • Could communicate in Japanese.
  • Measured distances and directions
  • Walked with his lower limbs
  • Gripped and transported objects

7
Development Issues
  • Design challenges
  • The need to coordinate sensors and artificial
    muscle
  • Intelligent programming
  • Efficient use of power

Operational Challenges
  • Need to create complex robot step-by-step
  • - Develop separate technologies and integrate
    them together
  • Not foolproof to operate
  • Difficult to program a robot to walk
  • To rely upon built-in operating systems to run
  • To be designed for a novice user
  • Lack of sufficient funds

8
Dealing with the Challenges
  • Severe shortcomings of contemporary approach
    leads to
  • Inventions of newer concepts of development
  • Used to fight the establishment
  • Solve many serious problems
  • Gains followers
  • General ideas followed to deal with the
    challenges are
  • More software innovations required
  • Move to cell manufacturing systems
  • Develop new programming language
  • Design new operating system if required

9
Approach towards their Working
  • Use of rule-based logic in robotic "brains (eg.
    Aibo, the pet dog)
  • - Program vast amounts of information
  • Neural networks is another approach to
    artificial intelligence (eg. Kismet)
  • - Work more like human brain
  • - Can handle ambiguity better than rule-based
    systems.
  • - Feature of "learning" - a helpful tool to
    add more human-like behaviors.
  • Stimulus-response mechanism (also known as
    subsumption architecture, eg. Cog)
  • - No memory or logical decision making
  • - Hard-wired responses to stimulation

10
Example of an Android Design
  • Taking the example of KISMET, an android with
    facial expressions
  • and emotions built at MIT, by Dr Cynthia
    Brenzeal.
  • Had head with jaws
  • Eyes had color CCD camera
  • Small motors to move facial features
  • A network of 3 integrated circuits
  • - Control
  • - Perception
  • - Attention
  • Required special software. 3 drives are
  • - Social drive
  • - Stimulation drive
  • - Fatigue drive

11
Kismets Expressions
Calm Interest Angry
Happy Sad Surprise
12
Another example of an Android being built by a
company
  • Asimo is built by Honda (2 years old).
  • Stands for Advanced Step in Innovative
  • Mobility
  • Small and light weight
  • Walks naturally
  • Arms move dynamically
  • Fingers are delicate
  • Walk up down the stairs
  • Flexible body parts
  • Make registered gestures
  • High-tech control processor
  • - Developed on its own
  • - 3 times better than current PCs
  • processors

Asimo and friend
13
Another example of an Android being built by a
company contd.
  • Latest version of Asimo can
  • Turn its head to follow moves
  • Recognizes preprogrammed faces
  • Respond with vocal welcome
  • Respond to couple of gestures

14
Some In-Process Android Projects
Robonaut - NASAs space android (2.5 years old)
Johnie- Institute for Applied Coco, a baby
gorilla project Mechanics at the Technical at
MIT University of Munich (TUM)
15
Popular Androids their Developers
  • Cog, built at MIT, can learn to recognize and
    grasp objects
  • Working as tour guides
  • Toy companies have started selling pet animals
    like robots
  • Dante, a spider-like robot serves geologists

Industries using Androids
  • Defense
  • Underwater and Geological Explorations
  • Space Projects of NASA
  • Nuclear and Chemical Laboratories
  • Hospitals
  • Tourism and Entertainment
  • Toys

16
Advantages of Androids
  • In general
  • Perform automated tasks to save on labor
  • One of the factors contributing to higher levels
    of productivity
  • Personalization and Ease of Use
  • Not only an appliance/machine
  • Better acceptance by humans
  • Provides personal touch
  • Can be used for domestic mundane tasks
  • Self explanatory repair mechanism

17
Future of Androids Fears
  • Can build itself - cost effectiveness
  • Can rapidly become super intelligent
  • Can become a rival to automobile industry
  • Estimation
  • - 10 US homes will have android within 12
    years
  • - 50 will within 20 years
  • Will androids be dangerous as portrayed in
    Hollywood Movies?
  • Though nothing can be sure unless we work with
    them. But positive
  • assumptions state that
  • - Androids will have built in (software)
    protection (Asimov's first law)
  • - Androids don't need money or food or
    possessions or clothes which can
  • drive them to hurt
  • - They are designed to serve humans not hurt
    them
