Details:

Kletter Maxe uses a simple gear mechanism to climb a 8.5 mm "Rebschnur" I used as climbing rope. The gears that are connected to the rope are 8 technic gears with 16 tooth as shown below.
The red arrows indicate how the gears rotate when the robot climbes up.

Here is a front and side view of Kletter Maxe hanging on the rope.

As you see in the side view the robot is balanced very good and the batteries are very close to the rope.

Source code comments:

The program assumes, that the robot is on the ground and thus the lower switch is pressed. The motor is switched on in UP direction until the upper switch hits the ceiling. Now the motor direction is toggeled and the motor stops when the lower switch is pressed again.
