So, What Is a Robot?

• A device that moves and responds to sensory
  input.
• Robota is the Czech word for forced labor
• Robotics introduced by writer Isaac Asimov I,
  Robot
• 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

Artificial Intelligence

• The branch of computer science concerned with
  making computers behave like humans.
• games playing programming computers to play
  games such as chess and checkers
• expert systems programming computers to make
  decisions in real-life situations
• natural language programming computers to
  understand natural human languages
• neural networks Systems that simulate
  intelligence by attempting to reproduce the types
  of physical connections that occur in animal
  brains
• robotics programming computers to see and
  hear and react to other sensory stimuli

So, How Does It Work?

Agents

• What is an agent?
• Perceives environment using sensors
• Acts on environment with actuators
• Percepts
• Agents inputs at any given time

Sensors and Actuators

• Sensors receive camera and video images,
  keyboard input, etc.
• Actuators act on the environment
• Robotic arm, wheel movement etc.

How IR Works

• Infra means below infra-red is light that has a
  lower frequency, or longer wavelength than red
  light
• Infrared light is used to illuminate the robot's
  path and determine when the light reflects off an
  object
• Used detect black and white, distance of
  objects, avoid objects and ledges

17
Think Headlights

• When light from headlights reflects off of
  obstacles, your eyes detect the obstacles any
  your brain processes them and makes your body
  move the car
• Infrared LEDs emit light
• If light reflects off of an obstacle, then the
  infrared receiver sees the reflected light
• The bot can then decide what to do
