Max - that link didn't have anything about LEGOs.

I haven't tried one but I'd definitely be interested.

Have you looked at LEGO Education website? http://www.legoeducation.us/store/Default.aspx?retest=1&domainalert=1&bhcp=1

I have several of their products (LEGO Motorized Simple Machines, Engineering level II, Motorozied MEchanisms) if you have questions.
