The standard supporting foot trajectories are one of the most basic parameters for gait control, because the legs have to follow the trajectories as long as the irregular degree of terrain and posture conditions are maintained. The introduced method goes through the processes of (1) projection of the gait scheme on a horizontal plane, (2) definition of the effective searching areas, (3) selec tion of a crab-walking pattern between x and y types, (4) generation of the stroke contour maps, and (5) selection of the longest stroke and its existing areas. The validity of the proposed method is verified by several computer simulations.<\/jats:p>","DOI":"10.1177\/027836499101000101","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T03:05:13Z","timestamp":1173582313000},"page":"3-12","source":"Crossref","is-referenced-by-count":57,"title":["Generalized Standard Foot Trajectory for a Quadruped Walking Vehicle"],"prefix":"10.1177","volume":"10","author":[{"given":"Shigeo","family":"Hirose","sequence":"first","affiliation":[{"name":"Tokyo Institute of Technology Department of Mechanical Engineering Science 2-12-1 Ookayama, Meguro-ku, Tokyo 152, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamu","family":"Kunieda","sequence":"additional","affiliation":[{"name":"Ishikawajima-Harima Heavy Industries Co., Ltd. 1-15, Toyosu 3-chome, Koto-ku, Tokyo 135, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1991,2,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1177\/027836498400300210"},{"key":"atypb2","volume-title":"The Robotics (in Japanese)","author":"Hirose, S.","year":"1987"},{"issue":"4","key":"atypb3","first-page":"289","volume":"1","author":"Hirose, S.","year":"1986","journal-title":"Adv.
