Hey there, I was thinking of a final year project for university and was wanting to make an interface from a gameboy advance sp to a robot. My goal is to be able to control the robot using the buttons on the gameboy (basically using the gameboy as the controller) which would be plenty of buttons for just about any robot that doesn't fly or swim. I also was wanting to be able to receive a video feed FROM the robot to know where it is. (Ideally this whole thing would be wireless so the robot wouldn't been in visable range of the user but at this point I'd be more than happy with a wired interface)
My first question is whether or not the comm port on the gameboy could support enough bandwidth for a small camera. I've read the comm port specs at http://nocash.emubase.de/gbatek.htm#communicationports and it thought it might be possible to receive a video feed using the high speed 2Mbit/s transfer rate, but I don't know what kind of overhead to expect, or what to expect from a camera. (I am assuming that is 2Mbit/s total, or 1Mbit/s each direction) As an alternative, I could try and build my own flashcart, possibly based on the retail A/V adpater found here: http://www.merconnet.com/product_info.php?products_id=458 . But I have never attempted to make a flash cart, so I'm not sure how hard it would be to make one capable of receiving video (audio would not be necessary) as well as send information to a robot specifying which button was pushed. If a flashcart would be the better way to go, I think I would like to be able to send data from the flash cart as well to avoid the need for making this interface require two peices (flash cart and comm port adapter). Thanks for your input!
