Versatile Passive Exoskeleton

We are developing versatile passive exoskeletons that use variable gravity compensation mechanism to provide lightweight, energy-efficient, and controllable means of assistive force to the human body. These robots will augment the capabilities of industrial workers (e.g., reduced muscle fatigue) in addition to assisting those with muscle weakness. As compared to a traditional passive exoskeleton, these systems help the wearer more efficiently by adjusting the optimal assistive force for the working condition (e.g., the weight of payload).

Variable Gravity Compensation Mechanism

The CVGC can be used to generate gravity compensation torque by using the cam and lever mechanism and can also amplify the target gravity compensation torque by varying the pivot point of the lever. The proposed CVGC has many advantages. Most importantly, it is designed as a compact, independent one-piece structure and is lightweight, meaning it can easily be used as a mobile platform with a simple modification. The CVGC can also have a full range of compensation angle (360°), so it does not restrict any of the original workspaces of the target platform when it is installed.
