The arrays are located on the toes of the robot and consist of a tuned, multi-link compliant suspension. The fundamental issues of spine allometric scaling versus surface roughness are discussed and the interaction between spines and surfaces is modeled. The toe suspension properties needed to maximize the probability that each spine will find a useable surface irregularity and to distribute climbing loads among many spines are detailed. The principles are demonstrated with a new climbing robot, SpinybotII, that can scale a wide range of flat exterior walls, carry a payload equal to its own weight, and cling without consuming power. The paper also reports how toe parameters scale with robot mass and how spines have also been used successfully on the larger RiSE robot.<\/jats:p>","DOI":"10.1177\/0278364906072511","type":"journal-article","created":{"date-parts":[[2006,11,13]],"date-time":"2006-11-13T14:29:33Z","timestamp":1163428173000},"page":"1165-1179","source":"Crossref","is-referenced-by-count":271,"title":["Scaling Hard Vertical Surfaces with Compliant Microspine Arrays"],"prefix":"10.1177","volume":"25","author":[{"given":"Alan T.","family":"Asbeck","sequence":"first","affiliation":[{"name":"School of Engineering, Stanford University, Stanford, California                         94305-2232,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangbae","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Engineering, Stanford University, Stanford, California                         94305-2232,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
