What is Robotics?

• Robotics is a science of modern technology of
  general purpose programmable machine systems

4
Main components of Robots

• Mechanical Platform/Hardware Base
• Sensor Systems
• Joints -gt degree of movement
• The Controller -gt Brain of the Robot
• Power Source
• Artificial Intelligence

5
Artificial Intelligence

• Reasoning
• Adaptation
• Decision Making
• Learning from mistakes
• Requires a lot of programming and
  sophisticated controllers and sensorial ability
  of the robot

6
Robot Behavior

• One of the most interesting aspect of the Robots
  in general is their Behavior
• Simplest behavior of a robot is locomotion
• - Joints and wheels are used as an underlying
  mechanism to make robot move from one point to
  another
• - Must include adaptability and Versatility

7
Adaptability and Versatility

• Adaptability Adjustment to the task being
  carried out. Robot must be able to complete the
  task no matter what interferences occur in the
  environment
• Versatility- robot should have such a mechanical
  structure that it carries out different tasks /
  same task in different ways

8
Behavior Contd

• Behavior can be expressed in different ways
• Action depending on environment Move away from
  obstacles, kick a ball, Jump across an obstacle
• Facial expression Smile, Frown
• Textual response happy, sarcastic, sad,
  critical

9
A successful Robot will give responses that
appear to be coming from a Human

• Human Are you smart?
• Robot What do you think? ltSarcasticgt
• Robot Smarter than you are! ltArrogantgt
• Robot Of course I am ltdefensivegt
• Robot I hope I am smart! ltless confidentgt

10
ELIZA and ALICE

• ELIZA
• 1996 computer program by Joseph Weizenbaum which
  made a spoof of Rogerian Therapist.
• It mostly rephrased many of the patients
  statements as questions and posed them to the
  patient
• Simple Pattern Recognition and Substitution of
  Key words into canned phrases

11
ELIZA and ALICE contd.

• ALICE (Artificial Linguistic Internet Computer
  Entity) AIML
• Richard Wallace is the author of AIML and
  co-founder of A.L.I.C.E Artificial Intelligence
  Foundation
• ALICE is a chat Robot

12
AIML (Artificial Intelligence Markup Language)

• It is an XML-compliant language
• Makes it possible to customize Alicebot or create
  one from scratch

13
AIMLContd

• Most important units of AIML
• ltaimlgt - Tag that begins and ends an AIML
  document
• ltcategorygt Specific path through the knowledge
  web along with the Response
• ltpatterngt - Input words
• lttemplategt - Output response

14
My Task

• Create a customized ALICE
• Generate different responses based on the current
  state (angry, happy, sad, etc.,)
• Different behavior AIML files will be finally
  integrated by Martin and myself.
