SIMULATION STUDY ON SPEED, RESISTANCE AND STABILITY OF UniKL AMPHIBIAN RESEARCH CRAWLER I (UARC I)

Abstract

Sub sea vehicles which well known as Remotely Operated Vehicle (ROV) are widely used in many scopes such as, inspection, exploration and even a search and rescue mission. Some ROVs are so advance with a robotic system that allowed underwater operation such as underwater welding and repairing underwater piping can be done without sending human to the work field. As to expend research on the various types of seafloor such as mud, sand, gravel and irregular steep terrain, ROVs able to handle or withstand the hydrodynamic effect such as added mass, buoyancy and centre of buoyancy. The UniKL Amphibian Research Crawler II (UARC II) is an improvement from the previous project, which is consist only the underwater crawler vehicle. The improvement of UARC II is by combining the crawler with jumping ability to avoid any obstacle more than 300 angles. Furthermore, the UARC II also consists a multiple function such as robotic arms, suction arm, camera, sensor, light and etc. So this paper is to present the simulation study on speed, resistance and stability and also to study the hydrodynamic effect on the (UARC II). The objective of this paper is to design the simulation, define real model simulation and compare both data. Computational Fluid Dynamics (CFD) is one of the methods to design the simulation. An experiment was conducted on land and underwater as to stimulate the result which able to make a comparison and also enhancement of the project.
