PROPULSION
Voith-Schneider Propellers
The Voith-Schneider propellers are a novel
approach to underwater propulsion. By utilizing two of the Graupner 2358
Voith-Schneider assemblies in a counter rotating configuration, the
Stingray is able to move in any relative direction in the horizontal
plane while simultaneously maintaining any arbitrary heading. This means
that with only two of these propellers, the Stingray can move forward
or backward, strafe left or right, turn on a dime or any combination
thereof.

Vertical Thrusters
The vertical thrusters are used by the Stingray
to control pitch, roll, and depth. A total of three vertical thrusters
are used on the Stingray: one vertical thruster in each of the wings and
one in the tail. Each thruster contains a Scorpion 22mm brushless motor
with an attached 2-blade RC boat propeller.
Each of these thrusters are assembled in house by the iBotics team. Read more about how these thrusters are built on the Waterproofing page.
