It seems like it may be rather hard to find such a pot. You may want to just use a standard pot, however, and program the robot to respond to ranges of analog input rather than a specific value. So that you could turn it approximately to the correct program, rather than the specific value.

If you don't have too many autonomous programs you could use a series of switches as a binary selector. You'd only need 5 bits (5 inputs out of the 4 ports) to cover the 12 modes you seem to need and more.
