This is an university project by my friend, Oscar Au, who design and make it for creative media students to learn what Arduino could do. All the parts can be bought off-the-shelf, and no custom parts is needed (except some wiring and cases of course). After simple assembly, you can use an Android device to control it with tilt / roll motion.
“Can we invite anyone come by and play the toy with their own mobile ?” This is what comes into our mind in first place.
A toolkit named Amarino is used to communicate between the mobile and the toy over bluetooth. It uses simple text commands. So the job should be easy.
Before we start working on a new version, we’ll bring it to Hong Kong Mini Maker Faire 2012 in coming month. We have extend the user’s manual, so being your Android mobile and play.
