Abstract
A method for extracting intended torque for a wearable robot includes a motor torque calculating step, a link rotation calculating step and an intended torque calculating step. In the motor torque calculating step, motor torque is calculated from the angular velocity of rotation of the motor. In the link rotation calculating step, the angular velocity of rotation of the link is calculated. In the intended torque calculating step, the motor torque and the angular velocity of rotation of the link are substituted into a disturbance observer, and an estimated value of the intended torque applied by a wearer is calculated.
