The edubot kits are a great idea, but I am disappointed in the mechanical aspects of the kits. Observing students working with them for the first time, they have a lot of trouble building square chasis, mounting motors and wheels so they don't bind, bulid a caster that works, etc. Square axels in a square hole don't turn too well. Mechanically/vision challenged individuals have trouble
with tiny collars and set screws.

The electrical components mated to a Lego or even K'nex chasis would be cheaper-better-faster. Since there is FIRST Lego League, I am surprised this was no done.

As a matter of fact - I think I will suggest to our team as a project figuring out how they could incorporate the Edubot motors on a Lego or K'nex.
