This is my first bot so I am sort of starting easy, but I am an over overachiever soo lol..
I am using a material called Sintra, using a 6mm piece for the base of the robot.
(pretty strong stuff)
The base is 8 by 12 inches. That will have four one inch stand offs in a 6 by 8 rectangle with a 3mm piece of sintra on top. (mainly just to protect the electronics but it will also be used to raise up some of the sensors.
For controls I am using two-three ATmega328p-pu Microcontrollers on the actual robot. Mainly to control motor directions, lights, sensors, etc.
Communicating via Serial(tx/rx)
I will also be building a remote control I can use to take control of the robot at any moment.
Sensors I am using so far are, light sensors and some range finders (act like feelers).
For the motors I am using a Quad half H-bridge. That can handle up to 36VDC at 1A.
I am designing this robot to be built so I can add to it.
I am thinking of designing some type of data logging system to map out my house.
I will keep you updated as I am in designing phase sort of like the alpha phase.
I will be building the robot sort of in sections testing it out on breadboards and then incorporating them all together.
EDIT: As for the actual motors as of right now I have two http://www.solarbotics.com/products/gm12a
Gm12a 100:1 but I may scrap them for this project as for they don't really have A LOT of speed to them.
It all depends if I can find a 1:3 ratio gear setup somewhere.
I would LOVE to eventually move up into a build with an actual computer as the brains.
