Well, this past week, as I was looking through hackaday I found a very interesting project. Juan Gonzalez has built a control using the wii fit board for a robot that he calls Skybot. A youtube video can be seen here at Wii fit board controlling Skybot .
"[Gonzalez]managed to control a robot of his own design with the balance board, making it turn when he leans to the sides and moving forward and back when he leans in those directions."
The best thing about this project is that the Skybot can be controlled from a Mac, GNU/Linux, FreeBSD, or Windows operating systems. The site for this project is in Spanish, so you may have to use Babel Fish or Google Translate to read it, but the site can be found at www.learobotics.com . It gives you the instructions you need to build a Skybot and maybe you can change it up and control it from your IPhone.
