TL;DR:

Problem: You have one remote, but a bunch of robots. You cannot address them individually; each robot will recieve every command. How do you get them into useful positions?

Solution: Each robot is slightly different from the other. if you can figure out how each one deviates from your control you may be able to use the error to create a control algorithm.

Sounds like trying to make a website look the same in all browsers. Though I suspect solving that is simply impossible :)
