It is becoming a major function in soft robotics; however, its application to support heavyweight is relatively niche. Although previous studies has developed several self\u2010healing tensile modules for tendon\u2010driven robots, these modules suffered from deficient healing strength because of the formation of surface oxides. This study proposes a biomimetic approach to enhance self\u2010healing performance. This approach exploits the motion of the robot to trigger the sloshing of liquid metal, which decomposes surface oxide. The method is validated using a benchtop module test, resulting in a healed strength of over tens of kilograms. Moreover, the module enables the tendon\u2010driven monopod testbed to perform a squat motion 13 times after a landing impact fracture and self\u2010healing sequence. The self\u2010healing module does not break during or after the squatting motion. To the best of our knowledge, this is the first demonstration of active self\u2010healing behavior using a life\u2010sized legged robot. Thus, this study provides a novel approach in the field of self\u2010healing robotics for improving self\u2010healing, thus contributing to medical robot and mechatronic designs, including rehabilitation, surgical, and diagnostic robots.<\/jats:p>","DOI":"10.1002\/aisy.202500040","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T08:33:22Z","timestamp":1748334802000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Liquid Metal Sloshing for High\u2010Load Active Self\u2010Healing System: An Application to Tendon\u2010Driven Legged Robot"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1920-3716","authenticated-orcid":false,"given":"Shinsuke","family":"Nakashima","sequence":"first","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Kento","family":"Kawaharazuka","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Yuya","family":"Nagamatsu","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Koki","family":"Shinjo","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Akihiro","family":"Miki","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Yuki","family":"Asano","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Yohei","family":"Kakiuchi","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Kei","family":"Okada","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]},{"given":"Masayuki","family":"Inaba","sequence":"additional","affiliation":[{"name":"Department of Mechano\u2010Informatics The University of Tokyo  Hongo Bunkyo\u2010ku 113\u20108656 Japan"}]}],"member":"311","published-online":{"date-parts":[[2025,5,6]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/MEX.1986.4307016"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10514-009-9171-6"},{"key":"e_1_2_9_4_1","doi-asserted-by":"crossref","unstructured":"Y.Nagamatsu T.Shirai H.Suzuki Y.Kakiuchi K.Okada M.Inaba in2017 IEEE\/RSJ Int.
