Key Motivators
  • Introductory computing courses serve as a gateway
    into the CS curriculum.
  • Should provide interesting and diverse range of
    examples and exercises.
  • Alignment of course content to student interests
    to increase engagement can have a positive impact
    on students choosing to enter computing as a
    major in college.
  • Most tasks should be attainable and provide a
    basis for supportive and positive feedback to
    students.

4
Additional Motivators
  • Use a personal robot
  • Let the needs of the curriculum drive the design
    of the robot, software, and text
  • Use tools that are easy to use, scale with
    experience
  • Create an accessible, engaging environment for
    new, diverse population of students
  • Computer Science ? programming
  • Make computing a social activity
  • Make computing a medium for creativity
  • Performances vs. competitions

A Personal Robot Kit
  • Color camera
  • 3 Light sensors
  • 2 IR proximity sensors
  • 2 Line sensors
  • Stall sensor
  • Speaker
  • 3 LEDs
  • 2 motors
  • Bluetooth wireless
  • Pen port
  • Myro Python Module

6
Myro Features
  • Simple, easy to use API even for
    non-programmers.
  • Seamlessly integrated with standard Python.
  • Plans to work with MSRS and .NET (will support
    multiple languages).
  • Design driven by curricular goals.

See Kumar et al. Engaging Computing Students
with AI and Robotics, Forthcoming in Spring 2008.

Hello World
  • Hello World
  • from myro import
  • speak(Hello, World!)

getObstacles() if Left
turnRight(turnSpeed) elif Right
turnLeft(turnSpeed) else
forward(cruiseSpeed)
Avoiding Obstacles from myro import
initialize(ask(What port?)) program
settings... cruiseSpeed 0.6 turnSpeed 0.5

A CS1 Assignment Exploring a Pyramid
12
Some Results
  • Learned CS concepts through robots
  • Robots made learning experience more hands-on,
    tangible, and exciting
  • Most frustrating parts were dealing with robot
    hardware inconsistencies
  • Viewed CS as a type of logic and problem solving
    requiring patience thought
  • Discovered that CS and robots are applicable to
    the real world

13
Another CS1 Assignment
Corral Exiting/Escape Imagine a corral (an
enclosed area with maze like partitions and an
entrance) with a light source at the entrance (as
shown in the figure to the right). Given the
robot's position, can we design a behavior that
will enable the robot to exit the corral?
14
Some Directions
  • Ability to draw
  • Ability to take pictures
  • Ability to make music/tones
  • Ability to play sounds and talk
  • Ability to express
  • Ability for robot interaction
  • Ability to have a web presence
