This research has been making the powered cock for fire engine. Recently the number of Japanese firemen decreases. They need device with a little load but it is forbidden to automate completely by fire defense law. So this research's purpose is to make the powered cock according to person's intention based on impedance control. First, we have confirmed relation of impedance parameter and cock's opening time period. In addition, we establish the method to predict cock's opening time period by initial value of controlling torque. By this method, evaluation consists of operation torque average and visual tracking error average has improved to the half. Second, we have confirmed to make responsiveness speedier based on friction control.The cock has strong static friction so there is longtime lag from giving the operation torque to opening of the cock. This friction control makes time lag shorter from 0.2sec to 0.03sec.
