Edison Robots (2) with Lego Kit for Building!!

These little robots work great, programming them with the edsoft software is really a breeze as well. I took one star off because One of the wheels broke when it fell off the coffee table and landed on the carpet and you cannot just buy spare wheels; you have to purchase akit that comes with a bunch of other parts and only 2 wheels -- the wheels seem to me to be the weakpoint in this system.
