*bzzzzz* wrong.
Frictional Force is mu * Normal force
The normal force is the force of the surface reacting against the robot, on a level surface this is equivalent to the object weight, but on a ramp or incline, this normal force is different. (The weight is split into some component forces).
This difference is an IMPORTANT distinction to make.
For more information contact your friendly neighborhood Physics Teacher/Professor/TA or pretty much any engineers you might know (although, they might have problems actually explaining it to you
).
