Modeling error, however, makes the control algorithms used difficult to apply to biped walking robots intended to transport human users. The \u201clanding pattern modification method\u201d we propose is based on nonlinear admittance control. Theoretical compliance displacement calculated from walking patterns is compared to actual compliance displacement, when a robot's foot contacts slightly uneven terrain. Terrain height is detected and the preset walking pattern is modified accordingly. The new biped foot we also propose forms larger support polygons on uneven terrain than conventional biped foot systems do. Combining our new modification method and foot, a human-carrying biped robot can traverse uneven terrain, as confirmed in walking experiments.<\/jats:p>","DOI":"10.20965\/jrm.2008.p0775","type":"journal-article","created":{"date-parts":[[2016,4,14]],"date-time":"2016-04-14T06:18:46Z","timestamp":1460614726000},"page":"775-784","source":"Crossref","is-referenced-by-count":19,"title":["Biped Landing Pattern Modification Method and Walking Experiments in Outdoor Environment"],"prefix":"10.20965","volume":"20","author":[{"given":"Kenji","family":"Hashimoto","sequence":"first","affiliation":[]},{"name":"Graduate School of Science and Engineering, Waseda University, 3-4-1 Ookubo, Shinjuku-ku, Tokyo 169-8555, Japan","sequence":"first","affiliation":[]},{"given":"Yusuke","family":"Sugahara","sequence":"additional","affiliation":[]},{"given":"Hun-Ok","family":"Lim","sequence":"additional","affiliation":[]},{"given":"Atsuo","family":"Takanishi","sequence":"additional","affiliation":[]},{"name":"Department of Bioengineering and Robotics, Tohoku University, 6-6-01, Aoba, Aramaki, Aoba-ku, Sendai 980-8579, Japan","sequence":"additional","affiliation":[]},{"name":"Department of Mechanical Engineering, Kanagawa University, 3-27-1 Rokkakubashi, Kanagawa-ku, Yokohama, Kanagawa 221-8686, Japan","sequence":"additional","affiliation":[]},{"name":"Department of Modern Mechanical Engineering, Waseda University, 3-4-1 Ookubo, Shinjuku-ku, Tokyo 169-8555, Japan","sequence":"additional","affiliation":[]},{"name":"Humanoid Robotics Institute (HRI), Waseda University, 17-41-2-04A Kikui-cho, Shinjuku-ku, Tokyo 162-0044, Japan","sequence":"additional","affiliation":[]}],"member":"8550","published-online":{"date-parts":[[2008,10,20]]},"reference":[{"key":"key-10.20965\/jrm.2008.p0775-1","doi-asserted-by":"crossref","unstructured":"Y.
