However, significant economic loss and environmental impact may happen if the farm fish escape from the holding facilities. Damaged fish cage is the dominant cause for escapes. Currently, the cages are inspected by divers. This is a risky job for human life and health. Such \u0026nbsp;risk to the divers may raise significantly as fish farms are being deployed further away from the shore.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EUnderwater remotely operated vehicles (ROVs) have been tested for aquaculture applications. However, cost of an ROV is usually too high for many fish farms, and experienced operators are needed to drive the tethered vehicle in complex environment like aquaculture sites. A more affordable robotic platform is needed to facilitate frequent inspection and early repair of the fish cage nets.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EResearchers at the Georgia Tech Systems Research Lab (GTSR) have developed an omni-directional surface vehicle (OSV) that achieves unmanned fish cage inspection. The unique design of the OSV allows safe and convenient operation in fish farms. The underwater camera of the OSV features motorized depth adjustment, which can inspect the cage at different depths. Algorithms onboard the OSV can recognize damage to the net in real-time. During each inspection, photos and locations of the damage are saved automatically for further analysis and repair.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Ch3\u003E\u003Cstrong\u003ECommercial Applications: \u003C\/strong\u003E\u003C\/h3\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003EAquaculture facility inspection\u003C\/li\u003E\r\n\t\u003Cli\u003ESubmerged infrastructure inspection\u003C\/li\u003E\r\n\t\u003Cli\u003ERescue and recovery operations\u003C\/li\u003E\r\n\t\u003Cli\u003EEnvironmental monitoring\u003C\/li\u003E\r\n\t\u003Cli\u003EMobile underwater acoustic communication gateway\u003C\/li\u003E\r\n\t\u003Cli\u003ERobotic platform for research and education\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Ch3\u003E\u003Cstrong\u003EBenefits \u0026amp; Advantages: \u003C\/strong\u003E\u003C\/h3\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003ELow-cost, easy to operate and maintain\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003EReal-time fish cage net damage detection\u003C\/li\u003E\r\n\t\u003Cli\u003ESafe operation in complex environment like fish farm\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003EMultihull design, good stability, manuvability, and redundency\u003C\/li\u003E\r\n\t\u003Cli\u003EModular and multipurpose design, good expandability\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Ch4\u003E\u003Cstrong\u003EResearchers:\u003C\/strong\u003E\u003C\/h4\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022http:\/\/fumin.ece.gatech.edu\/\u0022\u003E\u003Cstrong\u003EFumin Zhang - \u003C\/strong\u003E\u003Cem\u003EProfessor \u003C\/em\u003E\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EQiuyang Tao \u0026ndash; \u003C\/strong\u003E\u003Cem\u003EPhD student\u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBo Guo \u003C\/strong\u003E- \u003Cem\u003EUndergraduate Student\u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EKuo Huang \u003C\/strong\u003E- \u003Cem\u003EUndergraduate Student\u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ERobin Lam \u003C\/strong\u003E- \u003Cem\u003EUndergraduate Student\u003C\/em\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EChang Qin \u003C\/strong\u003E- \u003Cem\u003EUndergraduate Student\u003C\/em\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"An omnidirectional surface vehicle with the ability to inspect fish cage in aquaculture sites"}],"field_summary":"","field_summary_sentence":[{"value":"An omnidirectional surface vehicle with the ability to inspect fish cage in aquaculture sites"}],"uid":"33273","created_gmt":"2018-05-11 18:45:57","changed_gmt":"2018-05-11 19:07:12","author":"Emanuele Di Lorenzo","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2018-05-11T00:00:00-04:00","iso_date":"2018-05-11T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"606103":{"id":"606103","type":"image","title":"Omni-directional surface vehicle (OSV) prototype (left).
