Can anyone describe to me how a minibot can climb the pole?
Thanks!
Assuming you already understand how a powered wheeled vehicle can accelerate on a horizontal surface, the difference in the case of the minibot is that a normal force must be created (to press the wheels against the pole) for a minibot to climb the pole. Is that what you are asking ?

This normal force is typically created in one of three different ways:

1) magnets

2) spring-loaded grip

3) gravity acting on the center-of-mass of the minibot, creating around a pivot point a torque which presses the minibot against the pole
