The needs of oceanographic research have driven the development of autonomous underwater vehicles to be capable of great feats of autonomy and endurance. It is anticipated that future autonomous oceanographic surveys will be conducted using heterogeneous teams of vehicles to reduce cost and improve data quality. In a commonly proposed scenario, measurements for a survey are collected by a group of...
In those days, survey of deep sea floor is increasing importance and many kinds of facility are using for it. Autonomous under water vehicle (AUV) is one of the facilities and thought to be most effective method than remotely operated vehicle (ROV) or human operated vehicle. The main function of AUV is to design navigation course for survey by itself and complete the mission with keeping the course...
In this work, a visual interface for the assistance of a robotic wheelchair's navigation is presented. The visual interface is developed for the navigation in confined spaces such as narrows corridors or corridor-ends. The interface performs two navigation modus: non-autonomous and autonomous. The non-autonomous driving of the robotic wheelchair is made by means of a hand-joystick. The joystick directs...
This paper addresses the problem of following a moving target by an autonomous unmanned vehicle. The target may have higher maneuverability and a smaller minimum turning radius than the pursuing vehicle. The goal is to keep the autonomous vehicle as close as possible to the target all the time. We present a simple and constructive bearings-only guidance law and give its mathematically rigorous analysis.
