此种航行体的外形结构与ROV类似,它由超声接收机和发射机来实现航行体和母舰之间的联系,以使航行体能自主地在水下探测和搜索。另外,在其头部设置避障传感器,可规避水中障碍,还装有漏水传感器,可保证漏水时紧急上浮,避免昂贵的航行体沉入海底。 This kind of navigation body is similar in appearance and structure to the ROV, and it consists of an ultrasonic receiver and a transmitter to realize the connection between a navigation body and a mother ship so that the navigation body can autonomously search and search underwater. In addition, an obstacle avoidance sensor is arranged on the head of the vehicle to avoid obstacles in the water and a water leakage sensor, which can ensure the emergency float when leaking and prevent the expensive navigation body from sinking into the sea.
