Android phone as a controller
July 29, 2010
Hello there :)
I'm on the edge of purchasing an android phone. Looking at specifications around i thought: "Hey but this is the perfect controller for a robot!!" It has an incredible inventory of useful stuff: gps, compass for navigation, wifi, bluetooth and cellular for communication, huge screens for UI, speaker for talking, plenty of cpu, camera, easily programmable, and so on, all packed in a small package, all low power! And all for as less as $200! What do you want more ??
There's only a drawback: there's no simple way to phisically connect a device to peripherals :(
Practically all android phones lack any kind of serial, spi or i2c connection. They have USB but client only.
Anyone know of some hack to resolve the issue ? I tought of opening the phone and try to identify an i2c bus, but it's a little too invasive :) some hack on the USB? Some SPI ?
