Why do it? Isn't it too much?

I am a relative newbie when it comes to Robot making. I have messed around with Arduino micro-controllers but I haven't made anything significant. I decided I know enough to do this and a quick search on the internet of projects led me to the InMoov. It is advanced yet open-source. My only complaint might be that it does not yet have legs that work. But, maybe by the time I finish the top, someone will have made them.

Another reason is that I am a computer teacher at an International school in Laos. I want to create something that will excite some students enough for them to get into robotics and engineering.
Finally, my kids are now 16, 13 and 11. They are old enough to have interest and to take part. My second son will definitely get involved and probably do something in the future in a related field.
I enjoy this and it is fun!
