Passive acoustic detection unit for autonomous underwater vehicle subsystem based on hydrophone sensor

With the arrival of new robotic technologies such as an Autonomous Underwater Vehicle (AUV), a number of tasks that cannot be done by human now can be accomplished and bring human to reach the dangerous and unreachable areas. AUV can be related to the most invention which can reduce human's work using equipment and sensors that control and perform the particular tasks. In this sense, we propose a unit that able to fetch signals from beacon or acoustic pinger in order to move the AUV.
