To control crawler by Arduino from Android device

I am a member of Japan Android Group Kobe branch.
Japan Android Group is one of the community-based group that is not only for software designers'.,
but also for graphic/web designeders,music composers,phone users and various kind of people interested in Android platform.


And for me,I entered it to learn development around Android platform.
(I'm engineer for embedded systems)


By the way,recently,we're talking about making crawling car toy that is controllable from Android Phones via Bluetooth Serial port profile.
I am interested in sort of smart phones and electronic handicrafts as well,so I also discussing about it.

And the name of the crawler is Andy.


The system of this Andy is quite simple,the main controller is Arduino,and motor driver TOSHIBA TA7291P(we can buy it at Akizuki-denshi in Akihabara-town.2 pcs JPY300).


I've taken the prototype of Andy.Please check it!
