AUVs: From idea to implementation (MIT)
_Since the 1970s, when early autonomous underwater vehicles (AUVs) were
developed at MIT, Institute scientists have tackled various barriers to robots
that can travel autonomously in the deep ocean. This four-part series examines
current MIT efforts to refine AUVs’ artificial intelligence, navigation,
stability and tenacity._
As the search for oil and natural-gas resources moves into deeper and deeper
water, companies are facing increasing costs. Building and installing a single
offshore drilling platform now costs more than a billion dollars, so companies
are using their platforms as efficiently as possible. Advances in technology
have enabled them to service several oil fields from a single platform, and
much of the infrastructure for well operations has moved to the seafloor,
which may be as much as 4,000 meters — almost 2.5 miles — below the surface.
As a result, inspecting, servicing and repairing underwater equipment has
become an ever-greater challenge.
Many companies accomplish those tasks using remotely operated vehicles (ROVs),
robots that are operated by a person aboard a surface vessel. Because radio
signals do not propagate through seawater, the ROVs are connected to the
