IPRE Software

• Connecting Curriculum and Hardware
• Software Design Overview
• Short term goals for Spring 2007
• On to Hardware

Educational Robotics

• No one has really ever done this before!
• Using robots in CS1 is not the same thing as
  using robots in service of teaching CS1
• CS education is primary goal
• Robotics is the motivation
• A robot that is good for robotics is not
  necessarily a robot that is good for education,
  and verse vice-a

4
Software Development Overview

• CS1 and CS2 components are just the tip of the
  iceberg
• These are just gateway robots to more
  sophisticated systems
• Myro designed to span the needs of teachers and
  students from introductory coursework to research
  robotics, and beyond and create a smooth
  continuum
• Should be easy to do very interesting things

Myro, Spring 2007

• POLL-mode get sensor data when needed
• Some intelligence no need to POLL again within a
  minimum time span
• Make the client/server communications robust

12
Myro Interfaces

• Functions
• left(), right(), forward(), move()
• Object-oriented
• robot.left(), robot.right(), robot.forward(),
  robot.move()

13
Myro Simulator in Python

Myro code examples

• from myro import
• initialize(com5)
• forward(.5)
• rotate(.8)
• stop()
• for command in left, right, forward
• command(.7)
• stop()

15
Myro code examples

• from myro import
• robot Scribbler(/dev/ttyUSB0)
• robot.move(.4, .1)
• for i in range(4)
• robot.forward(1)
• time.sleep(3)
• robot.stop()
• robot.left(.6)
• time.sleep(5)
• robot.stop()
