Development of a new compliant exoskeleton device for elbow joint rehabilitation

With the development of human machine interaction technology, exoskeleton devices are widely researched in multiple fields in recently. In this paper, we proposed a design of compliant exoskeleton device for elbow joint which can be used in rehabilitation of upper limb. The new device can implement the complaint interaction between human's upper limb and exoskeleton device through adding one passive rotational joint and one passive translational joint based on one active rotational joint which is usually used in most of research in this field. At last, we also evaluate it according to analyzing the force between human's upper limb and exoskeleton device comparing to only one active rotation joint device.
