In considering alternative control schemes, however, the computational costs of evaluating continuum mechanic models of soft robots represent a significant bottleneck. We consider the use of lumped dynamic models for soft robotic systems. Such models have not been employed previously to design gaits for soft robotic systems, though they are widely used to simulate robots with compliant joints. A major question is whether these methods are accurate enough to be representations of soft robots to enable gait design and optimization. This paper addresses the potential \u201creality gap\u201d between simulation and experiment for the particular case of a soft caterpillar-like robot. Experiments with a prototype soft crawler demonstrate that the lumped dynamic model can capture essential soft-robot mechanics well enough to enable gait optimization. Significantly, experiments verified that a prototype robot achieved high performance for control patterns optimized in simulation and dramatically reduced performance for gait parameters perturbed from their optimized values.<\/jats:p>","DOI":"10.1017\/s0263574711000014","type":"journal-article","created":{"date-parts":[[2011,1,28]],"date-time":"2011-01-28T13:32:20Z","timestamp":1296221540000},"page":"823-830","source":"Crossref","is-referenced-by-count":26,"title":["Experimental verification of soft-robot gaits evolved using a lumped dynamic model"],"prefix":"10.1017","volume":"29","author":[{"given":"Frank","family":"Saunders","sequence":"first","affiliation":[]},{"given":"Ethan","family":"Golden","sequence":"additional","affiliation":[]},{"given":"Robert D.","family":"White","sequence":"additional","affiliation":[]},{"given":"Jason","family":"Rife","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2011,1,28]]},"reference":[{"key":"S0263574711000014_ref17","doi-asserted-by":"publisher","DOI":"10.1109\/MSPEC.2009.4808384"},{"key":"S0263574711000014_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-5193(83)90115-7"},{"key":"S0263574711000014_ref16","doi-asserted-by":"publisher","DOI":"10.1177\/0278364906069150"},{"key":"S0263574711000014_ref9","doi-asserted-by":"publisher","DOI":"10.1126\/science.1145803"},{"key":"S0263574711000014_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.mechmachtheory.2006.12.003"},{"key":"S0263574711000014_ref20","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00684.2004"},{"key":"S0263574711000014_ref3","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2005.851028"},{"key":"S0263574711000014_ref15","doi-asserted-by":"crossref","first-page":"3325","DOI":"10.1242\/jeb.202.23.3325","article-title":"Templates and anchors: Neuromechanical hypotheses of legged locomotion on land","volume":"202","author":"Full","year":"1999","journal-title":"J.
