A testbed for measurement of human arm impedance parameters

摘要

The development of an experimental testbed for the investigation of human arm impedance is described. A two-degree-of-freedom SCARA-configuration robotic arm with an endpoint force sensor has been developed for measuring parameters such as postural viscosity and dynamic stiffness and viscosity. The measurement device is used in disturbance tests to determine the degree and nature of impedance tuning during various tasks
