Hi and thanks for looking at this Instructable.
This is an Open Source multi platform teaching and learning project.
This build covers the use of 3D Printing, Laser cutting, basic electronics and Raspberry Pi as the main controller (although Arduino could be easily adapted).
Recent updates and background information on this Project can be found here.
I would strongly advise you to download the attached PDF as it contains all the links and photos to help you build this exciting developmental robot. (Another link is here if that does not work)
Please let me know of your build as there are exciting competitions and events planned to be run with a finale at Robocup each year.
