If your idea of "good" does not match what the RC expects, it won't work no matter how many times you check to see that it's "good". In order to help you, we need to know exactly how you have wired it. Answering "we wired it correctly" is not going to help. For example:

We have checked it with a voltmeter connecting between the where the white cable connects and where the red one connects and it shows the correct results.
But where did you connect the black wire? What measurement are you making, and what results are you getting? Answering "the correct results" does not help.

A potentiometer on the Robot Controller's analog inputs needs three wires. Black (ground) goes to one end of the pot. Red (+5) goes to the other end of the pot. White (signal) goes to the wiper.
