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

I am taking small steps, I'm doing it more for the fun of it and the
learning experience rather than any practical reasons.

I'm also going to start on an non robotic thing with a different
board, (Hence all my previous questions) A Wireless talking alarm
system. (Again more on the get it working and learning in the
process, rather than a more practical reason)
