My DS9 took a free library 3 hrs a day, one week class this summer robotics and loved it.

I'm interested in getting into this more for him at home. I'm thinking about the lego mindware and some of the Lego educational Robotics. Anyone have ideas about what is good to get started with?

Northwestern has a robotics online class they will probally offer again next summer. I was thinking their set might be good to start and that might present more options being able to use it in their class. Has anyone taken Northwesterns lego robotics classes online?
