Autonomous Underwater Vehicle (AUV) has limited energy capacity due to it being an embedded system. To overcome this limitation, the AUV can home into a docking station to recharge its battery. Several research has been conducted on the docking of AUV using vision. In some literatures, docking would fail if the target placed at the docking station is missing or disoriented from the camera view. This...
Underwater docking for an autonomous underwater vehicle is important in sense that the vehicle can stop at a docking station to recharge its battery, transfer data, and can be used for launch and recovery system. To perform docking, recognizing the station through vision is important. There are few researches conducted on underwater docking using vision to recognize targets as guidance for the underwater...
Blood pressure and heart rate are easily influenced by factors such as nutrition, medications, exercises, emotional stress and environment. Sound is one of the environmental factors that can influence blood pressure and heart rate. Different sounds have specific characteristics that affect the neuro-cardiovascular system differently. A physiological model of the neuro-cardiovascular system has been...
A hovering autonomous underwater vehicle usually has at least four thrusters which gives it the ability to propel in all directions. By decreasing the number of thruster, the AUV will have more room to accommodate for other devices. However, the AUV would become an under actuated system. From literature, there are various works had been studied to control an under actuated AUV. However, many of the...
An autonomous underwater vehicle (AUV) cannot operate for an extended amount of time due to limited energy supplied by battery embedded in its system. To prolong the AUV operation a docking station could be used so that the AUV can dock inside the station to recharge its battery. Several researches had been conducted for the docking of AUV using vision. Most of the research uses image-based visual...
Autonomous underwater vehicle can perform underwater docking to power up its battery in order to prolong operation thereby reduces maintenance and cost. Prior researches indicate visual servo technique is used for docking operation. Basically, image of markers placed on underwater station is captured and the vehicle surges towards the station. These previous works focuses on deep water environment...
