Underwater robotics research is gaining more considerable worldwide attention. Various types of underwater robots have been built in a variety of shapes, weights, sizes, and methods of propulsion. The researchers and scientists main focus is on designing lightweight, scalable Unmanned Underwater Vehicles that can relax on board the power requirement but also increase the mission time. This paper proposes the design of a triangular underwater robot for cleaning the biofouling on the aquaculture farm, where the triangular underwater robot equipped with two thrusters for the propulsion system. The conceptual designs of this underwater robot inspired by Stingray fish and this robot also named StingRay. This paper focuses on the preliminary design of the structure of the triangular underwater robot. The finite element analysis is implemented to the structure of the underwater robot to test the mass properties and the fluid flow of the structure. Solidworks is used to constructs a 3D robot model, and the finite element method is applied to the model. The analysis shows satisfactory results, where the triangular shape produces a low coefficient of friction. |
