The actuation system of the biped robot is based on the hybrid use of electric and pneumatic. The locomotion control architecture has been proposed to exploit natural leg dynamics in order to improve the biped robot walking stability. We also present a dynamic simulation which matches the biped robot and experiments with the real biped robot.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>The simulation and experiments result that introducing the variable stiffness ankle joint and the controller achieve a significant improvement in foot-ground impact and walking stability of the biped robot.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>The biped robot with variable stiffness ankle joints has a better walking performance under the control method.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3233\/thc-209046","type":"journal-article","created":{"date-parts":[[2020,4,28]],"date-time":"2020-04-28T14:10:31Z","timestamp":1588083031000},"page":"453-462","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis and control of biped robot with variable stiffness ankle joints"],"prefix":"10.1177","volume":"28","author":[{"given":"Zhenkun","family":"Lin","sequence":"first","affiliation":[{"name":"State Key Laboratory of Robotics and System, Harbin Institute of Technology, Harbin, Heilongjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xizhe","family":"Zang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Robotics and System, Harbin Institute of Technology, Harbin, Heilongjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuehe","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Robotics and System, Harbin Institute of Technology, Harbin, Heilongjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yubin","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Robotics and System, Harbin Institute of Technology, Harbin, Heilongjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Heng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Robotics and System, Harbin Institute of Technology, Harbin, Heilongjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,1,1]]},"reference":[{"key":"bibr1-THC-209046","doi-asserted-by":"publisher","DOI":"10.1109\/2.30721"},{"key":"bibr2-THC-209046","doi-asserted-by":"publisher","DOI":"10.1016\/j.robot.2011.06.006"},{"key":"bibr3-THC-209046","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(95)00029-1"},{"key":"bibr4-THC-209046","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtbi.2013.12.014"},{"key":"bibr5-THC-209046","doi-asserted-by":"publisher","DOI":"10.1109\/BIOROB.2010.5627767"},{"key":"bibr6-THC-209046","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-22876-1_29"},{"key":"bibr7-THC-209046","unstructured":"QiangZXiaoXYangW, et al.
