Novel Industry Application Suggestion

Most submarine uses propeller in the shape of fan to move the submarine.

A submarine propeller

However, the propeller are not suitable when it comes to low flow conditions, confined space, near the surfaces and in unsteady flow. Alternatives form of propulsion system need to be innovated to overcome this problem. Using turtle fin as propulsion system is one alternative to overcome this challenge. As mentioned in literature review, turtle's fins which shape like hydrofoil with it's skeleton consists of humerus and radius of short length with long phalanx allowed turtle to swim efficiently by decreasing the resistance from hydrofoil dynamic.

Pictures below show how's our design will look like.

As can be seen, the shape of the submarine still remain the same. However, on each side of the submarine, there are two components which are like fins of the turtle. This shape fins will be the propeller where it will move sideways just like turtle to propel the submarine forward. Just like turtle fins, the shape of this components is created like turtle fins to create streamlined hydrofoil so that the submarine can move efficiently because the resistance for the hydrofoil dynamic swirl is reduced. On the fins component, it is also attached propeller like fans to help push the submarine forward.

Other possible novel application
Robot Inspection has been commonly used these days for the purposes of inspecting area which is difficult or human can not reached. However, there are times where the surface of the inspection area can be rough or uneven which cause the robot inspection to fall down or flip over. Having an mechanism which can assist robot inspection will help it to stand on ground again to continue it's inspection work. A turtle have the ability to flip over when it was in upside down position. Turtles have smooth feature and flat shells with longer neck as pivot to help get themselves into position. The uneven shell also create imbalance that help turtle roll back to it's feet. Video below show how a turtle flip over when in upside down position.

Using this feature and apply it to robot inspection,it allowed the robot inspection to go back to it's original position in case the robot inspection fell over in upside down position.
