ANALISIS COMPUTATIONAL FLUID DYNAMIC (CFD) dalam PERANCANGAN TURBIN ARUS LAUT SUMBU VERTIKAL (VERTICAL AXIS OCEAN CURRENT TURBINE, VAOCT)

Indonesia di masa mendatang akan menghadapi krisis energi konvensional dalam hal kaitannya dengan peningkatan kapasitas kebutuhan, pasokan yang terus menurun, harga tinggi dan  permasalahan lingkungan yang ditimbulkan. Potensi energi laut Indonesia yang belum banyak dimanfaatkan dapat menjadi salah satu sumber energi alternatif yang bersih, dapat diandalkan dan terbarukan.  Untuk dapat memanen energi yang dihasilkan dari arus laut tersebut, Pusat Pengkajian dan Perekayasaan Teknologi Kelautan dan Perikanan (P3TKP)-BalitbangKP merancang dan mengembangkan twin series vertical turbin tipe drag release yang diharapkan dapat berputar pada putaran rendah. Studi lanjutan tentang bentuk blade-nozzle-guide vane serta kombinasi diantara ketiganya menjadi fokus utama agar dapat menghasilkan target output sebesar 10 kW

Coefficient diagram method for the control of an unmanned underwater vehicle

316-323 The operational demand for unmanned underwater vehicles has been growing rapidly in the recent past. For long range operations, such as oceanographic exploration and surveying, autonomous underwater vehicles (AUVs) which are equipped with on-board power and advanced control and navigation, have more promises to carry out tasks with the minimum operator intervention. Unlike other fixed platforms, autonomous underwater vehicles are particularly of interest due to their ability to provide continuous spatial and temporal observations. The safe operation of AUV relies on its autonomous navigation and control system. The paper is concerned with the synthesis of control system for an autonomous underwater vehicle using a coefficient diagram method. CDM is an algebraic approach applied to polynomial loop in the parameter space, where the so-called coefficient diagram is used as the means to convey the necessary design information and as the criteria of good design. The effectiveness of the control technique is demonstrated through a number of automatic control designs for motions in the longitudinal mode of AUV Squid, an autonomous underwater robotic designed and developed at Institut Teknologi Bandung. </smarttagtype

International Conference on Intelligent Unmanned Systems (ICIUS)

The International Conference on Intelligent Unmanned Systems 2011 was organized by the International Society of Intelligent Unmanned Systems and locally by the Center for Bio-Micro Robotics Research at Chiba University, Japan. The event was the 7th conference continuing from previous conferences held in Seoul, Korea (2005, 2006), Bali, Indonesia (2007), Nanjing, China (2008), Jeju, Korea (2009), and Bali, Indonesia (2010). ICIUS 2011 focused on both theory and application, primarily covering the topics of robotics, autonomous vehicles, intelligent unmanned technologies, and biomimetics. We invited seven keynote speakers who dealt with related state-of-the-art technologies including unmanned aerial vehicles (UAVs) and micro air vehicles (MAVs), flapping wings (FWs), unmanned ground vehicles (UGVs), underwater vehicles (UVs), bio-inspired robotics, advanced control, and intelligent systems, among others. This book is a collection of excellent papers that were updated after presentation at ICIUS2011. All papers that form the chapters of this book were reviewed and revised from the perspective of advanced relevant technologies in the field. The aim of this book is to stimulate interactions among researchers active in the areas pertinent to intelligent unmanned systems

Design and Construction of Hybrid Autonomous Underwater Glider for Underwater Research

The main goal of this paper was to design and construct a hybrid autonomous underwater glider (HAUG) with a torpedo shape, a size of 230 cm in length and 24 cm in diameter. The control, navigation, and guidance system were executed simultaneously using a Udoo X86 minicomputer as the main server and three BeagleBone Black single-board computers as the clients. The simulations showed a controlled horizontal speed of 0.5 m/s in AUV mode and 0.39 to 0.51 m/s in glide mode with a pitch angle between 14.13&#8728; and 26.89&#8728;. In addition, the field experiments under limited space showed the proposed HAUG had comparable results with the simulation, with a horizontal speed in AUV mode of 1 m/s and in glide mode of around 0.2 m/s. Moreover, the energy consumption with an assumption of three cycles of gliding motion per hour was 51.63 watts/h, which enabled the HAUG to perform a mission for 44.74 h. The proposed HAUG was designed to hold pressure up to 200 m under water and to perform underwater applications such as search and rescue, mapping, surveillance, monitoring, and maintenance
