The University in Lausanne is running a modular robot project called YaMoR. It's quite interesting. The cool thing about it: They also created Eve, a simulator for these robots. And it is written using Irrlicht.
BTW: I just released Irrlicht 0.11.0.
Must feel good to see your project really getting used, especially in this manner. I myself am a qualified mechatronic engineer and passed my qualification using a mixture of self made electronics controlled by software i wrote using Borland delphi. its an keen intrest of mines..
