The Edison Robot: <a href="http:&#x2F;&#x2F;meetedison.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;meetedison.com&#x2F;</a> was a successful KS project last year.  I got a pair, and haven&#x27;t played with them <i>too</i> much but they seem to work well.  They&#x27;ve got a nice visual programming environment, and are compatible with Lego.  And decently priced.
