This letter describes a novel pneumatically controlled hydraulic booster: Air-Hydraulic Servo Booster (AHSB) applied to water-hydraulic robots. This pump-less hydraulic circuit can control middle range water pressure easily by pneumatic proportional valves, where one can use tap water as the hydraul
This letter describes our novel hydraulic circuit, referred to as the hydraulic hybrid servo booster, and its application to hydraulic manipulator. The circuit embeds a servomotor controlled pump into a valve bridge so that the high-speed position can be achieved in a hybrid, cost-effective, and pre
This letter presents the control method and system of a four-legged, four-wheel-drive hydraulic powered rover that can traverse irregular terrain such as agricultural or forest landscapes while carrying manipulators and other tools to do heavy-duty work. The rover is equipped with driving wheels at
We propose a novel hydraulic hybrid servo drive for robotic applications. This method embeds a small servo-controlled pump into a hydraulic metering circuit. The circuit is compactly integrated into a servo-unit, then replicated for each joint, and connected to one common low-pressure line. Thanks t…
