I came across a neat little module that has java embedded in it and is essentially a cell phone. But it has access to several external peripheral that would be nice for robotics. The module is a little picky about it's power and how stuff is connected to it. So my thought was to build a breakout board and a small robot controller for the module and produce some PCBs of it. The module has I/Os and ADC as well as UARTs and even USB. So my thought was a simple robot controller using java as a language and if need be you can drop a sim card in and have it report back to email/sms/tcp what ever your desire. I'm working on the power supply design now. What kind of power output would be good for a small 2 motor wheeled robot? Also what else would you all like to see on something like this?
