The vertebrate limb pattern (e.g. shoulder, elbow, wrist and digits) has been proven to be very successful in many different applications in the animal kingdom. However, the actual level of optimality of the limb for each animal application is not clear because for some cases (e.g. whale flippers and bird wings), the basic skeletal layout is assumed to be highly constrained by evolutionary ancestry. This paper addresses this important and fundamental question of optimality by analysing six limbs with contrasting functions: human arm, whale flipper, bird wing, human leg, feline hindlimb and frog hindlimb. A central finding of this study is that the vertebrate limb pattern is highly versatile and optimal not just for arms and legs but also for flippers and wings. One key design feature of the vertebrate limb pattern is that of networks of segmented bones that enable smooth morphing of shapes as well as multifunctioning structures. Another key design feature is that of linkage mechanisms that fine-tune motions and mechanical advantage. A total of 52 biomechanical design features of the vertebrate limb are identified and tabulated for these applications. These tables can be a helpful reference for designers of bioinspired robotic and prosthetic limbs. The vertebrate limb has significant potential for the bioinspired design of robotic and prosthetic limbs, especially because of progress in the development of soft actuators.<\/jats:p>","DOI":"10.1088\/1748-3190\/ad66a3","type":"journal-article","created":{"date-parts":[[2024,7,23]],"date-time":"2024-07-23T15:40:09Z","timestamp":1721749209000},"page":"051004","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Universal optimal design in the vertebrate limb pattern and lessons for bioinspired design"],"prefix":"10.1088","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2689-508X","authenticated-orcid":true,"given":"Stuart","family":"Burgess","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"bbad66a3bib1","doi-asserted-by":"publisher","first-page":"42","DOI":"10.1016\/j.gde.2021.02.005","article-title":"Diversification of the vertebrate limb: sequencing the events","volume":"69","author":"Saxena","year":"2021","journal-title":"Curr.
