The fundamental physical constraints on the size, proportion and dynamics of natural water-walkers are enumerated and used as design criteria for analogous mechanical devices. We report devices capable of rowing along the surface, leaping off the surface and climbing menisci by deforming the free surface. The most critical design constraint is that the devices be lightweight and non-wetting. Microscale manufacturing techniques and new man-made materials such as hydrophobic coatings and thermally actuated wires are implemented. Using high-speed cinematography and flow visualization, we compare&nbsp;the functionality and dynamics of our devices with those of their natural counterparts.<\/p>\n\n\n\n<p class=\"tw-text-wide has-small-font-size wp-block-paragraph\">See&nbsp;<a href=\"http:\/\/math.mit.edu\/~bush\/wordpress\/wp-content\/uploads\/2012\/10\/Robots_Hu_Prakash_Chan_Bush.pdf\">Hu, Prakash, Chan and Bush (2010)<\/a><\/p>\n\n\n\n<p class=\"tw-text-wide has-small-font-size wp-block-paragraph\">PRESS: &nbsp;<a href=\"http:\/\/en.wikipedia.org\/wiki\/Robostrider\">Wikipedia<\/a>&nbsp;, &nbsp;<a href=\"http:\/\/news.bbc.co.uk\/2\/hi\/science\/nature\/3126299.stm\">BBC News<\/a><\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5,"featured_media":2011,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-3827","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-bio","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Biomimetic water-walking robots - John W.
