Keri Collins, a doctoral student at the <a href=\"http:\/\/www.bath.ac.uk\" target=\"blank\">University of Bath<\/a> in England, developed a robot called Gymnobot (for Gymnotiformes, a group of fish species including knifefish) using the fish as a model. The robot&#8217;s flexible fin, attached to a rigid body, is tangle-proof, according to laboratory tests. When complete, Gymnobot will help scientists study marine life in coastal waters, where varying terrain and habitats are tricky to navigate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The most vulnerable part of any underwater robot is its propeller, which can be easily damaged on rocky terrain or get caught in submerged plants.<\/p>\n","protected":false},"author":13,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[53,11,32,6,8,23],"tags":[],"class_list":["post-1095","post","type-post","status-publish","format-standard","hentry","category-biomimicry","category-in-the-mag","category-marine-biology","category-nature","category-science","category-science-update"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/1095"}],"collection":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/users\/13"}],"replies":[{"embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/comments?post=1095"}],"version-history":[{"count":8,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/1095\/revisions"}],"predecessor-version":[{"id":1160,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/1095\/revisions\/1160"}],"wp:attachment":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/media?parent=1095"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/categories?post=1095"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/tags?post=1095"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
