terminology
Terminology
  • Artificial Intelligence – The collective attributes of a computer, robot, or other device capable of performing functions such as learning, decision making, or other intelligent human behaviors.
  • Autonomous Agent – A hardware (or software) based system that has the following properties:

autonomy - able to operate without the direct intervention of humans or others

social ability - able to interact with other agents and possibly humans

reactivity - able to perceive their environment and respond to changes that occur in it

  • Agency – A particular system composed of intelligent agents, such as computers or robots, that cooperate in order to solve a problem.
  • Behavior Engineering – A methodology used to develop behavior- based autonomous agents.
fresh kitty
Fresh Kitty
  • Modular, inexpensive, autonomous mobile robot
  • 4 wheel toy car design
  • Max. speed of 1 foot/sec
  • On-board microcomputer supervises and supports the exchange of information
  • Rotating turret holds 4 sonars
  • Turret also holds an infrared sensor to detect infrared rays
  • 32 light sensors detect objects in front of the robot
  • Bumpers all around the robot used to follow walls
  • Radio modem to communicate with remote agents

SPOT
  • Autonomous mobile robot
  • 2 independent wheel design
  • Max. speed of 1 foot/sec
  • On-board microcontroller supervises and supports the exchange of information
  • Turret that holds infrared emitters that can be detected at a distance of up to 20 feet
  • Bumpers all around the robot used to follow walls
  • Radio modem to communicate with remote agents
how do spot and fresh kitty work together
How do SPOT and Fresh Kitty work together?
  • SPOT also holds a small brush on its back
  • SPOT finds a wall and uses its bumper system and sensors to follow edges and collect dust with its brush
  • Through radio frequency and infrared communication SPOT can bring the dust back to Fresh Kitty who has a vacuum cleaner waiting to suck it up
robocup
RoboCup

RoboCup is an international research effort to promote autonomous robots.

  • Robots must cooperate in…
    • Strategy acquisition
    • Real-time reasoning
    • Multi-agent collaboration
    • Competition against another team of robots

RoboCup
  • Each robot has…
    • Pentium 233MHz
    • Linux OS
    • Video camera and frame grabber
    • Sensor System
    • Kicker
how to the robots make decisions
How to the robots make decisions?
  • Control is based on a set of behaviors
  • Each behavior has a set of preconditions that either…
    • Must be satisfied
    • Are desired
  • A behavior is selected when all of the “musts” become true
  • A behavior is selected from several behaviors based on how many desired conditions are true
applications of ai and robotics
Applications of AI and Robotics
  • Industrial Automation
  • Services for the Disabled
  • Vision Systems
  • Planetary Exploration
  • Mine Site Clearing
  • Law Enforcement
  • And Many Others…

the humanoid cog
The Humanoid COG
  • MIT’s finest
  • Broken down COG is just a bunch of sensors and actuators
  • Except for legs and a flexible spine, COG has all the major degrees of freedom of the human upper body
  • Sight exists through video cameras
  • Hearing, touch, hand motion, and speech are being added soon
why build a human like robot
Why build a human-like robot?

Brought to you by Rodney Brooks

  • Our bodies are critical to the representations that we use for internal thought and language
  • If a robot is looks like a human then it will be natural for humans to interact with it in a human-like way
  • To develop similar task constraints
