Going with the flow (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._
Anyone who has steered a boat knows how much effort is needed to keep the boat
on course when currents are pushing it in different directions. Now, MIT
researchers have developed sensors that can measure the pressure of flows
around an oceangoing vessel so that it can utilize rather than fight those
flows, saving energy and improving maneuverability. Other work aims to go a
step further: to change flows from patterns that impede progress to patterns
that will help.
Flows around autonomous underwater vehicles (AUVs) and other vessels — from
ships to submarines — can significantly affect their performance. For example,
when a vessel going 20 miles per hour turns sharply, it pushes into the
current on one side and creates swirling eddies on the other; as a result, its
speed can drop suddenly to seven miles per hour. The behavior of control
surfaces such as rudders and propellers can also be ...
