"Avoid workplace accidents, vrrm! Safety first, zrrt!
--Floor Supervisor

The Floor Supervisor is a character mentioned in The Legend of Zelda: Skyward Sword. Several signs bearing the Floor Supervisor's name are found in Lanayru Desert, near the area where the generators need to be reactivated. The Floor Supervisor has provided the Ancient Robots with various information on these signs, such as a reminder to avoid workplace accidents and insight into the Temple of Time monthly cleaning assignments.

Because the Floor Supervisor uses terminology such as "vrrm", "zrrt" and "vrrt" on its instructional signs, it seems likely that it is also an Ancient Robot.
