A method for on-line water current velocity estimation using Lol-cost autonomous underwater vehicles
(Massachusetts Institute of Technology, 2020)
Advances in the miniaturization of microelectronics has greatly contributed to the proliferation of small, low cost autonomous underwater vehicles (AUVs). These affordable vehicles offer organizations a flexible platform ...
A planned approach to high collision risk area
(Massachusetts Institute of Technology, 2020)
This thesis examines the transition of a vessel from the open ocean, where collisions are rare, to a high risk and heavy traffic area such as a Traffic Separation Scheme (TSS). Previous autonomy approaches generally view ...
Stochastic acoustic ray tracing with dynamically orthogonal equations
(Massachusetts Institute of Technology, 2020)
Developing accurate and computationally efficient models for ocean acoustics is inherently challenging due to several factors including the complex physical processes and the need to provide results on a large range of ...
Modifiable stability and maneuverability of high speed unmanned underwater vehicles (UUVs) through bioinspired control fins
(Massachusetts Institute of Technology, 2020)
Underwater Vehicles generally have control fins located only near their aft end, for making controllable changes in directions. This design allows for stability of control; however, the turns are typically large in comparison ...
Signal absorption-based range estimator for undersea swarms
(Massachusetts Institute of Technology, 2020)
Robotic swarms are becoming increasingly complex on the surface and in air due to highspeed and reliable communication links, Global Positioning Satellites (GPS), and visual support to relative navigation. However, the ...
