I'm not sure if gravity causes the 'upward' force to be greater. The upward force would have to be greater for the minibot to go up, but the downward force is the weight of the robot which is made up of mass times gravity so the upward force needs to overcome gravity.
Don was not saying that the "upwards force" is greater than the "downward force", due to gravity.

He was saying that the "upwards force" is greater than the "downward force due to gravity".


Gotta love the English language.
