Brain: I'm thinking of an epia TC6000E it has a DC-DC controller. and I can run it off a cf card (not much memory) and add a wireless card to control this robot through the web: (as well as have some programming)
this one is pretty cool there's room inside for it:
Control: Ideally i'd like to control front/reverse and direction using a dual H-bridge (dual H-bridge) and a serial port.
looked at the Motor mind B/C but not sure exactly how to get those working on com pots..
planning on using this robot to chase after the dog while i'm at work :) thus adding a webcam and web control :)
hopefully u guys can help me put the hardware together
