Development of an Electro-Hydrostatic Actuator CADUCEUS and an Actuator-Equipped Rotary Mechanism

Journal of Robotics and Mechatronics
An actuator for achieving the same force in both directions, and a mechanism for supporting rotary motion with the actuator are proposed. By fabricating models and performing tests, the action of the actuator mechanism, and its application on an excavator was demonstrated.

Design and Evaluation of a Torque-Controlled Ankle Exoskeleton Using the Small-Scale Hydrostatic Actuator: miniHydrA

Actuators
A small-scale electro-hydrostatic actuator, termed miniHydrA, was developed based on biomechanical requirements for gait and integrated into an ankle exoskeleton. The key advantage of this actuator concept lies in its compact size and the low mass of its

Enhanced Operation Mode Design and Motion Control of a Dual-Redundancy Electro-Hydrostatic Actuator

Actuators
In dual-redundancy electro-hydrostatic actuators (EHAs), the dual pumps are mainly designed for safety, where the cylinder is controlled mainly by one pump while the other one is standby for redundancy. However, such a strategy is basically like a single-
