Probulator

The Probulator is a device at the Applied Cryogenics lab to examine newly awoken defrostees. Exactly how the device works or what it does remains someone ambiguous, as every time we see it, the camera is always elsewhere when the action takes place.

Before usage, the subject must take off his or her clothing before lying on the board, though they may hover slightly over the board. The machine is then operated by the Faith Assignment Officer.

The probulator is apparently also capable of satisfying other robots in a very pleasing manner, or at least Bender describes its capabilities as "knows how to please a man". Presumably, one could assume the probulator is female.

Production
In "Space Pilot 3000", it was originally intended for a much longer scene with Fry on the Probulator, where after inserting a tube into his ears, and filling his head with liquid, would cause flashbacks to be shown to the viewer, and assumingly the Faith Assignment Officer, or Turanga Leela in this case.
