Abstract
Bilateral control is a teleoperation system enables to transmit the information about force sense. And, hydraulic actuators of high power weight ratio are often used in ultimate environments. Open loop hydraulic circuits, which are generally used, contains servo valves in the structure. But using servo valves are the cause of the low backdrivability. However, the robot can have high backdrivability using close loop hydraulic circuits with servo pumps. In this research, we use an electric actuator as a master robot and a hydraulic actuator made up of a close loop hydraulic circuit as a slave robot and bilateral control is realized.
