SuGo NXT was initially a project created to ease the creation of Mindstorms NXT Sumo robots based on the NXT brick and the NBC programming language.
The original sugo-nxt project is available on sourceforge at http://sourceforge.net/projects/sugo-nxt/
A new project is brewing though. One built around the Openelectrons NXShield for Arduino and Lego NXT. This will bring a world class embedded development environment (Arduino) and a world class entry level robotics prototyping platform (Lego NXT). I’m documenting my successes in the meantime in my blog.
