Besides I have a thing for free open-source code, which seems more in tune with my philosophy that information and knowledge should be free that resonates with Processing. Anyway, will see if I can develop two versions, that robot arm is certainly of interest. I'm also thinking of building a personal mobile robot to carry my luggage, it has been a personal idea for some time and I really hope to get to that but sadly I still need more resources if I'm to get it built.
