Abstract

In underwater field, Remotely Operated Vehicle (ROV) and Autonomous Underwater Vehicle (AUV) are created to help human do marine research. AUV is an unmanned or fully sensors robotic vehicle that is using high technology to bring new capabilities to work in the subsea environment. One of the problems facing by AUV is the depth control since it may loss during surveillance because autonomously navigate in the sea. Thus, this project focused on the design and development of a low cost AUV with small size and high performance with its depth control. AUV need to be in small size to ease the mobility of the AUV when it performs tasks. Different speed will be used to test and evaluate the depth control since the depth also influenced by its speed. In designing the AUV, SolidWorks software is used and undergoes various simulation tests such as stress and strain test and stability by referring the center of mass. Next, the hardware that discussed and selected included frames, hull, enclosure box, propulsion and submersion that achieve a certain performance in terms of reliability and controllability. This project uses pressure sensor MPX5700AP as depth control to determine the depth of AUV submersion. AUV uses an AfroESC 30A to control the speed for Blue Robotics T200 thruster to move it along vertical and horizontal axis that automatic operate based on the programming coding. In this project, the scope of the study focused on the interface between mechanical and electrical design with the small size (70cm X 50cm X 30cm) made of acrylic that waterproof and the submerge range of depth in between 2 to 6 meters. The AUV is going to undergo a series of field test at the end to evaluate its ability and performance in the swimming pool task.
