what gear ratio do you guys suggest? we don't need it to be fast here. we just need to help move along the robot.
thanks for any suggestion.
P.S. this is my first post.

Cool we are doing almost the same thing. For my senior project we too are building a motorized cart to carry the robot. Except we are using two wheel chair motors that were donated, we have the motors in a direct drive straight to the wheel chair wheel. Even might use the controls from the wheel chair too.
I have no idea on the correct gear ratio, we almost used the chain drive using an electric car motor, but my teacher brought out a donated motorized wheel chair and that quickly changed our minds.
GOOD LUCK.
