The active Exoskeleton is a human interface for motion capturing and force interaction.The System is fixed at four points to the human body and can interact with the user at the upper shoulder, upper arm and forearm.
The four human fixing points are connected via a kinematic structure with nine degrees of freedom. Six of these joints are hydraulically actuated and one is pneumatically actuated. The combination of hydraulic- and pneumatic actuation offers the possibility to adapt the system stiffness to different motor skills of the user.
The hydraulic actuation is performed with vane actuators which are controlled via a proportional valve to regulate flow and pressure.The force interaction is measured with force sensors in the human fixing points and pressure sensors in the hydraulic circuit. The Exoskeleton is backdriveable and can also used in a free running mode.
