The rotation axis of human knee joint varies according to knee flexion angles. That is, human knee movement is spatial with dominant flexional rotation. Knee joints of most lower-limb exoskeletons were, however, realized with a simple revolute pair for design simplicity. Wearing the knee joint with a simple revolute pair constrains inevitably natural parasitic motion of human knee joint. Rigid con...
