What they need to do is make it like a PDA with a compact flash slot. Then
you could expand as needed. You could connect two controllers to communicate
via 802.11 or bluetooth, etc.
Or a CPU with CAN? It would be fairly cheap. Connect everything with 1-2
wires.
The minimum I/O would be what they have already in the RCX, plus 4-8 more
ports for sensors. The RCX should have a smaller footprint ( ipod size )
with a built-in rechargeable battery ( via solar, USB, Firewire and wall
plug ).
A smaller footprint would require different connectors for everything,
instead of the 2x2s, but why not? What would be so bad about that?
If the sensors and motors had some smart ICs to allow addressing, then they
could be connected to a bus ( i.e. stacked for power, ground and control ).
I think we're starting to cross the boundary that lego faces, they want this
thing to be used by kids ( and I guess adults now also ). If they jam a ton
of I/O in the controller, the cost goes up, parents may tend not to buy it
for their kids. But if they don't add more I/O, the adults will look
elsewhere for a more powerful controller.
Is there anyone else out there developing something? ( besides JCX ). Is
lego even doing anything here? I would imagine if they were we would have
heard about it by now, so I am assuming they are not. I'm surprised there
isn't an "open source" hardware and software project for this right now...
