Does anyone know if Rug warrior program in the book "Mobile Robots - Inspiration to implementation" can be run on a Handyboard? Has anyone run the Rug Warrior on Handyboard/Lego kit? Can the handyboard facilitate the same components? Thanks Liam (23 years ago, 10-Mar-02, to lugnet.robotics.handyboard)
