Man, that is some questionable advice!
We used encoders on all 4 wheels, a pot on the arm and an ultrasonic sensor on the front and rear. Our bot simple rolled forward X feet (measured by the encoders), raised the arm to the 9' height (measured by the pot), released the ubertube and backed off some. We used the ultrasonic sensors to align for minibot deployment.
Reliable sensors are a HUGE advantage in autonomous mode and can be used to automate certain movements in teleop mode (like releasing a tube and lowering an arm in perfect sequence). If you understand them, program them correctly and test them thoroughly - USE THE SENSORS!
HTH
