first time you boot them up, a random name is generated in the format +of two uppercase letters followed by three digits, such as RX837 or BC811. + +Every once in a while we need to reset a robot to its factory settings, +which means that their name gets wiped. The next time you ask, it will +respond with a new random name. + +The names must be random: they should not follow a predictable sequence. +Random names means a risk of collisions. Your solution must ensure that +every existing robot has a unique name. + +## Source + +A debugging session with Paul Blackwell at gSchool.
