... ABSTRACT For the problem of recycling AUV with manipulator, this paper starts from the aspects of kinematics modeling of manipulator, visual perception of target position, trajectory tracking control. Based on ROS to construct a simulation environment, and release visual information through...

... of the three icebergs, aerial photography of the above water and sonar survey of the underwater parts were carried out, which made it possible to build their 3D models and perform numerical simulation of their hydrodynamic parameters. Drag coefficients (for steady movement) and added mass (for accelerated...

... ABSTRACT The simulation of the operating performance and operating parameters of the excavating and conveying system of a cutter suction dredger has always been a research hotspot and difficulty. The single mechanism model has problems such as weak timeliness and large calculation deviations...
