Not only this is an excellent Hunt, I also respect you for taking your time to compose a good description with images and videos. Most Hunts are just a few words and a link and you have to visit the website to learn more about the product.
The product has a lot of complexity. Even a very smart adult can get into robotics with Robotics Workshop and not feel like they are being talked down like some kids. There are many sensors and a great detailed manual and very easy to use software. It's ttally worth the $249.95 price.
