The Review Unmanned Surface Vehicle Path Planning: Based on Multi-modality Constraint [article]

Chunhui Zhou, Shangding Gu, Yuanqiao Wen, Zhe Du, Changshi Xiao, Liang Huang, Man Zhu
2020 arXiv   pre-print
This paper introduces the research progress of path planning based on the multi-modality constraint.  ...  The path planning of multi-modality constraint research can be classified into three stages in terms of its basic ingredients (such as shape, kinematics and dynamics et al.): Route Planning, Trajectory  ...  One is based on Control Theory, and the other is based on random sampling. BASED ON CONTROL THEORY The first one is based on Control Theory.  ...
