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.
To learn more about how Voith-Schneider propellers work, see Voith-Turbo's website. While you are there make sure to try the Interactive Voith-Schneider Propeller Program.
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 assembeled in house by the iBotics team. Read more about how these thrusters are built on the Waterproofing page.
