In the movie, Prometheus, the ship's
crew tosses a few robotic orbs into the corridors of an ancient alien
ship. The robotic drones fly through the ship scanning the area to
produce a detailed, holographic map. Today, Google has essentially
been doing the same thing with Google Street View, sending out cars,
bikes, and even snowmobiles to geo-map as much as possible. These
images are tied to GPS coordinates, and Google has even mapped the
interior of some buildings. However, the movie Prometheus was
released after this technology had already been developed, but the
concept of geo-mapping robotic drones is still sci-fi, only because
it hasn't been done yet with robots. The lasers emitted from the
drones in the movie suggest something similar to the lidar used by
current satellites to map the topography of glaciers. Essentially,
the drones in Prometheus aren't much of a stretch considering current
technology, but sci-fi has a way of taking current tech and advancing
it just a bit further.
