In a broader sense, robots have to face two common tasks during exploration, namely, walking on the drylands and swimming through the water. This research aims to design and develop an amphibious robot, which incorporates a webbed duck feet design to walk on different terrains, swim in the water, and tackle obstructions on its way. The designed robot is compact, easy to use, and also has the abilities to work autonomously. Such a mechanism is implemented by designing a novel robotic webbed foot consisting of two hinged plates. Because of the design, the webbed feet are able to open and close with the help of water pressure. Klann linkages have been used to convert rotational motion to walking and swimming for the animal\u2019s gait. Because of its amphibian nature, the designed robot can be used for exploring tight caves, closed spaces, and moving on uneven challenging terrains such as sand, mud, or water. It is envisaged that the proposed design will be appreciated in the industry to design amphibious robots in the near future.<\/jats:p>","DOI":"10.3390\/robotics8030077","type":"journal-article","created":{"date-parts":[[2019,9,6]],"date-time":"2019-09-06T02:59:22Z","timestamp":1567738762000},"page":"77","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Design and Implementation of a Quadruped Amphibious Robot Using Duck Feet"],"prefix":"10.3390","volume":"8","author":[{"given":"Saad Bin Abul","family":"Kashem","sequence":"first","affiliation":[{"name":"Faculty of Robotics and Advanced Computing, Qatar Armed Forces\u2014Academic Bridge Program, Qatar Foundation, 24404 Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2605-5280","authenticated-orcid":false,"given":"Shariq","family":"Jawed","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Computing and Science, Swinburne University of Technology, 93350 Sarawak, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jubaer","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Computing and Science, Swinburne University of Technology, 93350 Sarawak, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uvais","family":"Qidwai","sequence":"additional","affiliation":[{"name":"Faculty of Computer Engineering Signal and Image Processing Qatar University, 24404 Doha, Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kashem, S.B.A., Jawed, S., Ahmed, J., and Iqbal, A.
