[oopic] Re: Extra memory (Future plans for robot to map room details)

After looking into this more, I'm thinking some kind of wireless link
to my PC is a much better Idea.

On top of that, it opens a whole new window of things to play with.

Turning the ooPIC board into a controller board with some built in
intelligence, which gets it's main commands from a PC. Then the PC can
handle storing (And displaying) the map. It can also tell the robot
where to go and how to get there.

I need to save up my pennies, I've found this device which seems to
make the RS232 connection wireless.

I'm planning on writing the PC end in VB.NET and use the serial as a
way of communicating. (I can add in the wireless but it later when the
normal serial cable has proven the theory)
