right now (without the PCB and components) it will fit underneath 3/4 of the doors in my house!!! the only think that could stop it is stairs!!!

I was thinking i could stack the boards 2 or 3 high, and that would give lots of room for all the sensors and other "gadgets" that i would like to add.. It would also be a lot smaller if i went with all SMT stuff and make everything myself instead of using prebuilt components. at the moment in designing it to use a serial motor driver, which uses a 9-pin header, a pic12f629 and a dual h-bridge chip. if i put the h-bridge directly on my board, and ran it off of the 18f6585, it would be tiny... at the moment, im using it for simplicity, it uses a 4byte command to control direction and speed or both motors.

With the mapping, i was thinging of doing it somewhat like a micromouse would. the room would be divided into little squares, and then it would decide which squares it can go in, and which ones it cant..

i would like to make a list of different "missions" for robots, not just for me, but for anyone else that just plays around with this stuff. to start, here are some of the things im working on, and some others that i would like to make someday:
workin on:
house mapping
cave exploring - lots of old mines around my place
snowplow

others:
photophobic
phottropic
lawnmower
sumo competition
micromouse
firefighting
minesweeping

if anyone has any others, lets hear them... im sure there are lots of other things out there...
