Ocean Wave Active Compensation Analysis for Redundant Hybrid Boarding System: A Multi-Task Motion Planning Method

Journal of Marine Science and Engineering, 2023
In this paper, to effectively solve the joint motion planning of a nine-DOF redundant hybrid boarding system in the process of ocean wave active compensation, we present a multi-task motion planning (MTMP) method for the redundant hybrid boarding system.
