Inspired by this biological function, an artificial lateral line system (ALLS) was built on a moving bionic carrier using the pressure sensor in this paper. When the carrier operated with different speeds in the flow field, the pressure distribution characteristics surrounding the carrier were analyzed by numerical simulation, where the effect of the flow angle between the fluid velocity direction and the carrier navigation direction was considered. The flume experiment was carried out in accordance with the simulation conditions, and the analysis results of the experiment were consistent with those in the simulation. The relationship between pressure and fluid velocity was established by a fitting method. Subsequently, the pressure difference method was investigated to establish a relationship model between the pressure difference on both sides of the carrier and the flow angle. Finally, a back propagation neural network model was used to predict the fluid velocity, flow angle, and carrier speed successfully in the unknown fluid environment. The local fluid environment perception by moving carrier carrying ALLS was studied which may promote the engineering application of the artificial lateral line in the local perception, positioning, and navigation on AUVs.<\/jats:p>","DOI":"10.3390\/s20051512","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T11:59:36Z","timestamp":1583841576000},"page":"1512","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Flow Field Perception of a Moving Carrier Based on an Artificial Lateral Line System"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3353-117X","authenticated-orcid":false,"given":"Guijie","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Mechanical and Electrical Engineering &amp; Key Laboratory of Ocean Engineering of Shang Dong Province, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanhuan","family":"Hao","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering &amp; Key Laboratory of Ocean Engineering of Shang Dong Province, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingting","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering &amp; Key Laboratory of Ocean Engineering of Shang Dong Province, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuikuan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering &amp; Key Laboratory of Ocean Engineering of Shang Dong Province, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4629-633X","authenticated-orcid":false,"given":"Mengmeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering &amp; Key Laboratory of Ocean Engineering of Shang Dong Province, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atilla","family":"Incecik","sequence":"additional","affiliation":[{"name":"Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, Glasgow G1 1XQ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhixiong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechanical, Materials, Mechatronic and Biomedical Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"026013","DOI":"10.1088\/1748-3190\/aaa786","article-title":"Bio-inspired all-optical artificial neuromast for 2D flow sensing","volume":"13","author":"Wolf","year":"2018","journal-title":"Bioinspiration Biomim."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"999","DOI":"10.1109\/JMEMS.2007.902436","article-title":"Design and Characterization of Artificial Haircell Sensor for Flow Sensing with Ultrahigh Velocity and Angular Sensitivity","volume":"16","author":"Chen","year":"2007","journal-title":"J.
