A new biomechanical template for walking
Meeting Abstract 32-2 Thursday, Jan. 5 13:45 – 14:00 A new biomechanical template for walking BISWAS, T; BHANDAWAT, V*; RAO, S; Loyola University, New Orleans; Duke University; Duke University tbiswas@loyno.edu Legged locomotion is complex: it requires precise coordination amongst multiple joints within a limb and coordination between limbs. However, many approaches to legged locomotion employ simplified approaches […]
