WallCrawller Update:

I have good news and bad news.

The good news is that the gears arrived and i managed to free some time to continue with the project.

Heres the bad news... the shaft that holds the gears has become loose. So the gears slip now. When the robot starts crawling forward on the whiteboard, the force on the magnetic wheels causes the shaft to bend backwards. This pops the gear teeth to pop out and get stuck and stall the motor.

It seems i will need to order a new Servo...
