Helmholtz resonance in a piezoelectric–hydraulic pump-based hybrid actuator [PDF]

, 2011
This paper demonstrates that a hydraulically acting Helmholtz resonator can exist in a piezoelectric–hydraulic pump (PHP) based hybrid actuator, which in turn affects the volumetric efficiency of the PHP.

Researches on the hybrid electro-hydraulic actuators

Journal of Engineering Sciences and Innovation
The new generation of „more electric” actuators involve simpler, cheaper and lighter power generation and distribution architectures. To achieve this goal, the electro hydraulic servovalves controlled by electrical signals have to be eliminated in the frame of the new concept „Power-by-Wire”, which uses electric power to actuate flight control surfaces,

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a
