Abstract

The invention relates to a small-size water surface robot device and a self-adaptive flow optimizing navigation method. The robot device comprises a hull, a driving device and a control device, wherein the control device comprises a water flow rate sensor, a navigation device and a central controller; the navigation device comprises a GPS sensor, an electronic compass and an inertial navigation module to realize the automatic navigation. The self-adaptive flow optimizing navigation method comprises the steps of: (1) receiving a GPS signal to obtain absolute coordinates; (2) acquiring real-time speed and real-time angles; (3) judging the distance from the device to a barrier; (4) acquiring a direction of forward motion; (5) acquiring the water flow rate; and (6) controlling a course. The small-size water surface robot device has the advantages of small volume, light weight, energy conservation, labor conservation, low cost and convenient use. The navigation method can optimize traveling routes, save energy, and simultaneously prevent turnover, collision and avoid obstacles to fulfill the aim of stable operation.

Description

technical field [0001] The invention relates to a water surface robot device and a navigation method thereof, in particular to a small water surface robot device with an automatic control device, and a small water surface robot adaptive water flow optimization navigation method. Background technique [0002] Surface robots, also known as unmanned ships, are unmanned intelligent surface platforms that can be equipped with various monitoring, monitoring and exploration equipment for different applications. Its application is gradually being promoted. Navigation methods are critical for surface robots that need to drive fully autonomously without a human operator. The navigation algorithm means that after inputting the destination of the unmanned ship, the surface robot will drive to the destination according to its own location. During this period, it is necessary to go through mathematical calculations, issue instructions to its own propellers and rudders (if it is a double...
