Previous approaches have simplified robot manufacturing by using fluidic control circuits, but these rely on labor\u2010intensive methods like silicone molding and manual assembly, limiting accessibility and replicability. Recent work, including this work, has demonstrated 3D\u2010printed robotic grippers and crawlers with embedded control circuits, but generating cyclic control outputs for legged locomotion in rough terrain remains challenging. This study addresses the challenge with a monolithic 3D\u2010printable four\u2010phase bistable oscillating valve, capable of generating coordinated motion of multiple limbs from a steady source of pressurized air. The ability of the oscillator to control an electronics\u2010free autonomous legged robot capable of walking on rough terrain, which can be fully fabricated on a desktop 3D printer without postassembly is demonstrated. The robot is operational immediately upon connection to an air supply. This development marks a significant step toward accessible, customizable, and biodegradable autonomous soft robots that can be produced using desktop 3D printers with no human intervention.<\/jats:p>","DOI":"10.1002\/aisy.202400876","type":"journal-article","created":{"date-parts":[[2025,1,26]],"date-time":"2025-01-26T22:15:40Z","timestamp":1737929740000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Monolithic Desktop Digital Fabrication of Autonomous Walking Robots"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6174-7421","authenticated-orcid":false,"given":"Yichen","family":"Zhai","sequence":"first","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering University of California, San Diego  La Jolla CA 92093 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8281-0549","authenticated-orcid":false,"given":"Jiayao","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering University of California, San Diego  La Jolla CA 92093 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert","family":"De Boer","sequence":"additional","affiliation":[{"name":"BASF 3D Printing Solutions B.V.  7821 AT Emmen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3993-5253","authenticated-orcid":false,"given":"Martin","family":"Faber","sequence":"additional","affiliation":[{"name":"BASF 3D Printing Solutions B.V.  7821 AT Emmen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6608-9867","authenticated-orcid":false,"given":"Rohini","family":"Gupta","sequence":"additional","affiliation":[{"name":"California Research Alliance BASF Corporation  Berkeley CA 94720 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7821-7777","authenticated-orcid":false,"given":"Michael T.","family":"Tolley","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering University of California, San Diego  La Jolla CA 92093 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,26]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201006464"},{"key":"e_1_2_10_3_1","doi-asserted-by":"crossref","unstructured":"R.Adam Bilodeau E.
