TL;DR: In this paper, the authors proposed an underwater target cooperative tracking method based on consistency estimation and dormancy scheduling. And the method comprises the following steps: disposing two types of underwater sensor nodes, and arranging that the nodes are at a low-frequency reflection detection function at initial time; the dormancy sensor nodes periodically determining whether to be converted into an activation state; sensors entering a wakeup state sending water sound pulse signals for detecting a target and accordingly determine the position of the target; for the purpose of obtaining target position information with quite high precision, performing consistency estimation on observation information

TL;DR: In this article, an auction mode-based underwater robot multi-target selection strategy is proposed, which comprises the following steps: in a given monitoring water area, multiple underwater moving robots with perceptive functions are deployed, and each robot determines self position information and target position information via a sensor carried with the underwater moving robot itself; the position information is used for calculating a cost function, a value function and a gain function; a virtual auction public platform is then built, and based on a Dutch decreasing public auction form, auction is carried out on multiple targets.

TL;DR: In this paper, an obstacle avoidance method based on distance and parallax information is proposed for underwater robots, where a control device performs overall path planning on the underwater robot according to an operation task and nautical chart database information.

TL;DR: In this article, the authors proposed a regional optimal solution algorithm for underwater moving target precise positioning, which comprises the steps that underwater sensor nodes are deployed, and location information of the nodes is acquired; an activation threshold of nodes is set, and the nodes are enabled to initially stay at a dormant state; each dormant node periodically judges whether to turn into an activated state or not; the nodes which stay at the activated state, send marked acoustic waves so as to carry out detection on a target; the node, whose residual energy is the highest, in the activated nodes is searched so
