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.
