Electro-hydraulically actuated forestry manipulator: Modeling and Identification

open access: yes2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012
We present results of modeling dynamics of a forestry manipulator, in which we consider its mechanics, as well as its hydraulic actuation system. The mathematical model of its mechanics is formulated by Euler-Lagrange equations, for which the addition of friction forces is straightforward.

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion

open access: yesSmartBot, Volume 2, Issue 2, June 2026.
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,
