I went to brick fair 2013 2 days ago and I saw an exhibit with dancing NXT robots! They were running off of a specially designed code made for lego platforms (robots) called NXC. I found that very interesting so I asked the person there about NXC. he said it was designed for lego platforms and that it was only on the internet and he said that it was a redesigned programing language called C.
I'll give you updates on it!

I learned this! It is really C(C+ or C++? I don't know) but you can only have commands that work for the Mindstorms NXT robots. I think I still remember it. It is fun and interesting. I made a biped(AT-ST, from an instructions book) that avoided walls(I did the programming, the book came with only 1% worth of it). I want it to keep a record of where walls are, but I cant keep track of how far he moves with each step. It changes, and it slips occasionally. I wonder how small of an acceleration the accelerometer can sense.
