Paulson School of Engineering and Applied Sciences<\/a> and the <a href=\"https:\/\/wyss.harvard.edu\/\" target=\"_blank\">Wyss Institute for Biologically-Inspired Engineering<\/a> have created an upgraded version of the <a href=\"https:\/\/wyss.harvard.edu\/technology\/autonomous-flying-microrobots-robobees\/\" target=\"_blank\">RoboBee<\/a>\u2014an autonomous flying microbot with bee-like wings\u2014that is able to fly, dive into water, and then fly out of the water, which is something that has been challenging for robotics of that size. And it&#8217;s very cute to watch.<\/p>\n<div style=\"max-width: 576px;\" data-iframely-id=\"rxTrhNH\" data-embedded-url=\"https:\/\/video-images.vice.com\/_uncategorized\/1508956859972-giphy-6.gif\" class=\"article__embed article__embed--iframely\">\n<div style=\"left: 0; width: 100%; height: 0; position: relative; padding-bottom: 75%;\" data-iframely-smart-iframe=\"true\"><iframe  src= width=\"100%\" height=\"420\" frameborder=\"0\" ><\/iframe> <\/div>\n<\/div>\n<p>Human&#8217;s don&#8217;t really have an issue with getting in and out of water, because our weight allows us to break through the water&#8217;s <a href=\"https:\/\/water.usgs.gov\/edu\/surface-tension.html\" target=\"_blank\">surface tension<\/a>.
