However, to undertake these missions, they need to overcome the challenges of power requirements for takeoff and the difficulty of transitioning reliably between the air and water media. The use of superhydrophobic surfaces offers solutions to these challenges by reducing the wetted surface area of such robotic vehicles. In this article, a range of superhydrophobic surfaces is analyzed for wettability and robustness performance to ascertain their benefits as a design feature for drag reduction in aerial\u2013aquatic robotic vehicles. The silicon dioxide nanoparticle spray coating show the most superhydrophobicity measuring a static water contact angle of 174.8\u00b0. The coating's robustness tests yield a similar performance to that of laser\u2010engraved brass with 200\u2009\u03bcm groove separation, displaying a contact angle of 133.0\u00b0 after ten finger strokes. The silicon dioxide nanoparticle spray is then used for drag reduction testing due to its ease of coating complex 3D geometries among the techniques explored in this study. The spray is applied to the hull of a sailing\u2013flying robot, which resulted in the robot's drag reduction averaging 40% in the hydroplaning regime.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202100185","type":"journal-article","created":{"date-parts":[[2022,9,10]],"date-time":"2022-09-10T08:59:22Z","timestamp":1662800362000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Use of Superhydrophobic Surfaces for Performance Enhancement of Aerial\u2013Aquatic Vehicles"],"prefix":"10.1002","volume":"5","author":[{"given":"Daniel","family":"Gortat","sequence":"first","affiliation":[{"name":"Aerial Robotics Laboratory Imperial College London  South Kensington Campus London SW7 2AZ UK"}]},{"given":"Alejandro Ortega","family":"Ancel","sequence":"additional","affiliation":[{"name":"Aerial Robotics Laboratory Imperial College London  South Kensington Campus London SW7 2AZ UK"}]},{"given":"Andre","family":"Farinha","sequence":"additional","affiliation":[{"name":"Aerial Robotics Laboratory Imperial College London  South Kensington Campus London SW7 2AZ UK"}]},{"given":"Raphael","family":"Zufferey","sequence":"additional","affiliation":[{"name":"Aerial Robotics Laboratory Imperial College London  South Kensington Campus London SW7 2AZ UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5857-4953","authenticated-orcid":false,"given":"Mirko","family":"Kovac","sequence":"additional","affiliation":[{"name":"Aerial Robotics Laboratory Imperial College London  South Kensington Campus London SW7 2AZ UK"},{"name":"Materials and Technology Centre of Robotics EMPA\u2014Swiss Federal Laboratories for Materials Science and Technology  8600 D\u00fcbendorf Switzerland"}]}],"member":"311","published-online":{"date-parts":[[2022,9,10]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10336-009-0441-z"},{"key":"e_1_2_11_3_1","unstructured":"R.
