Most people know that I'm a big fan of simple robots in the classroom. While the more elaborate ones look great, I'm all for having a design that is quick to build with as few parts as possible. This allows classrooms to more quickly get into the programming side of things.
So here is my miniVEX design. It can be made by any of the VEX-IQ starter packs that were released after Summer 2014. If you have a pre-summer 2014 VEX-IQ kit, have a look here for a design that will work with your kit. - old miniVEX
This design is the one I use for all the activities in my upcoming Teacher Resource book.
