Based on the principle of UAV, this paper design and realize underwater quadrotor with high function, which equipped with electronic gyroscope. Based on ensuring the detection accuracy, simplify structure and realize the automatic control of underwater quadrotor gesture, use image video real-time transmission to help operation carry out command transmission on underwater equipment. The test results show that the platform can be used in underwater work condition for a longtime and reduce danger for operator operations. It has some practical and innovative significance in underwater investigation and unknown waters detection.
