Heterogeneous Wettability-Based Construction of Two-Phase Interfaces for Underwater Reversible Adhesion. [PDF]

open access: yesAdv Sci (Weinh)
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...

基于不确定事件威胁度评估的UUV任务重规划

open access: yes智能科学与技术学报, 2022
无人水下航行器(UUV)的任务规划直接关系到水下作业的效率。由于水下环境复杂,不确定事件频发,有时UUV按照最初的规划很难完成任务。针对UUV任务规划问题,提出基于不确定事件威胁度评估的UUV任务重规划策略。首先,UUV根据任务点的分布进行初始任务规划,采用自组织网络算法为UUV规划访问多任务点的时间顺序及访问任务点的最短路径。其次,判断 UUV 执行任务过程中出现的不确定事件类型,并转换为贝叶斯网络的形式。最后,利用贝叶斯网络对不确定事件的威胁度进行评估。如果威胁度大于阈值,则 UUV 进行任务重规划;
