"The USB source will be mounted in some kind of housing that the device can very easily and clumsily fit in to. Both the USB source device/charger and the robot itself will contain a radio [definitely 802.11g later], but for now a simple FM oscillator would probably be good. The software will also have access to this radio. The device will maintain contact with it’s base station. IR won’t be any good here as the device needs some kind of a range. I’ll need to assess the practicality of range vs hardware."
