In view of the influence of uncertain situations on Unmanned Surface Vehicle (USV) autonomous navigation, an approach to evaluate USV autonomy level based on multi-attribute decision making theory is presented. The method is to build evaluation model by giving a problem description of decision and supplying objects design. Using the model to construct a directed assignment graph, the assessment result...
Autonomy evaluation is one of challenging research topics in unmanned systems, since the appropriate autonomy level can make the overall system more reliable and more robust However, the autonomy level of human and unmanned vehicle is contextual about the changing situation and system states. This paper describes an approach to evaluate the autonomy for Unmanned Surface Vehicle (USV) system in the...
The paper proposes a new kind of near-field reactive obstacle-avoidance method for USV. First, the dynamic window (DW) of USV is calculated according to the kinetic characteristics. Heading window and translational velocity window are obtained by using “divide and conquer” strategy dealing with the dynamic window of USV. At second step, the constraint from obstacles are analyzed by using tangent method,...
