Programming seems to be a struggle and not all are that interested - they just 'want to build a robot' but have little idea what it actually entails.
This is kind of what I expected. I think if the programming involved -- this is how
you go forward, this is how you turn, this is how you fire the death-ray, etc and
provide a goal then the interest level will be there.
I've been tinkering with the idea of emotions for it - angry (charging at objects), scared (hiding) stuff like that.
