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

Main components of Robots Mechanical Platform/Hardware Base Sensor Systems Joints -> degree of movement The Controller -> Brain of the Robot Power Source Artificial Intelligence

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

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”

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

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

A successful Robot will give responses that appear to be coming from a Human Human: “Are you smart?” Robot: “What do you think?” Robot: “Smarter than you are!” Robot: “Of course I am” Robot: “I hope I am smart!”

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

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

AIML (Artificial Intelligence Markup Language) It is an XML-compliant language Makes it possible to customize Alicebot or create one from scratch

AIMLContd… Most important units of AIML - Tag that begins and ends an AIML document – Specific path through the knowledge web along with the Response - Input words - Output response

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.
