A Critical Analysis of Flow-Compensated Hydrostatic Single Rod Actuators: Simulation Study
Actuators, 2020 It is well established that the differential cylinder area in pump-controlled single-rod actuators creates the need of correctly switching the connections between the main circuit lines and a charge circuit, in order to provide means for equalising the ...

A Critical Analysis of Valve-Compensated Hydrostatic Actuators: Qualitative Investigation
Actuators, 2019 Hydrostatic actuation has gained interest from both academia and industry due to the unquestionable energetic advantages when compared to valve-controlled actuators; the main feature being the absence of throttling losses due to the direct control of the

Low-Level Force-Control of MR-Hydrostatic Actuators
IEEE Robotics and Automation Letters, 2021 Precise and high-fidelity force control is critical for new generations of robots that interact with humans and unknown environments. Mobile robots, such as wearable devices and legged robots, must also be lightweight to accomplish their function. Hydrostatic transmissions have been proposed as a promising strategy for meeting these two challenging ...

High-stretch, tendon-driven, fiber-reinforced membrane soft actuators with multiple active degrees of freedom [PDF]
Communications EngineeringMost soft actuators with multiple active degrees of freedom do not take advantage of the full extensibility of elastomer. Here we introduce a technique for better utilizing this extensibility for more versatile soft actuators. Embedded tendons that slide

Thermal Characteristic and Analysis of Electro-Hydrostatic Actuator
IEEE AccessElectro-hydrostatic actuators (EHAs) are widely utilized due to their superior integration and high power-to-weight ratio. However, the elimination of a centralized oil source in EHAs restricts the cooling capacity of the system, leading to potential ...
