I can end some speculation. (I really need to learn Italian, if I'm going to
keep posting here)
Hidden under the battery boxes are a pair of motor controllers from Hi-Technic.
These are samples, and I'm not sure their future plans, but if there is enough
interest, they may produce them.
The controllers each require their own battery box, to avoid grounding issues
with the RCX. They're a 4x4 box that's 5 plates high, and has 3 wires coming
out. As you've seen, the wires are RCX/controller-input, battery box, and motor
output.
I'm using the controllers because I don't think an all-LEGO polarity switch
control scheme will be quick and/or accurate enough for the navigation
requirements of this robot.
I'm still working on the design. I've tested it outside ONCE, so I'm not really
sure how well the whole system will stand up to the current demands of driving
through grass and up hills.
I'm hoping to have a LEGO robot that can enter a RoboMagellan event like this:

When I make more progress, I'll get more information posted on the web.
