Ok, I've found what looks like a good gearhead motor at an online surplus store, but I am not sure if it is powerful enough
How do I figure that out?

I have a robot that will weigh 10-15lbs and move about 3-4 inches per hour. ITs an indoor bot

These are the specs on the gearhead motor
12VDC gearhead motor. 7.5RPM @ 12VDC. Draws 100mA @12VDC no load. 3/8" dia X 5/8" flatted shaft. Solder terminals
L: 3-1/2"(Body) H: 3-3/4" O/A W: 2-1/2" 
WT: 1.5

Does this look sufficient to move the robot?
I've been trying to figure it out mathematically, but it just becomes confusing.
