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
Bryn Mawr College
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
Bryn Mawr College
Myro Interfaces
• Functions– left(), right(), forward(), move()
• Object-oriented– robot.left(), robot.right(),
robot.forward(), robot.move()
