We have started building a comprehensive example using mbeddr C. We have selected Lego Mindstorms together with the nxtOSEK operating system. OSEK is a real-world embedded operating system, so our example does have some real-world relevance.
The main two reasons for builing the thing is that we need a showcase for our talk and booth at Embedded World 2012 and that we want to eat our own dogfood. The latter has already proven a good idea, we’re finding bugs, problems and places for improvements left and right (and we’re addressing them of course).
As of now, we have the motors, the gun and the compass at work (the compass is the thing on the big pole — we try to avoid interferences). Next will be the bumpers, the light sensor and the sonar. A lot of fun 🙂
