Design of Novel Knee Joint Mechanism of Lower-Limb Exoskeleton to Realize Spatial Motion of Human Knee

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…
