Control of a hydraulically-actuated quadruped robot leg
2010 IEEE International Conference on Robotics and Automation, 2010This paper is focussed on the modelling and control of a hydraulically-driven biologically-inspired robotic leg. The study is part of a larger project aiming at the development of an autonomous quadruped robot (hyQ) for outdoor operations. The leg has two hydraulically-actuated degrees of freedom (DOF), the hip and knee joints.

Robust microvalves for hydraulic actuators
SPIE Proceedings, 2003Robust compact hydraulic actuators are extremely needed in space industry where payload is critical. Microvalves are key component for compact hydraulic actuators. Robust microvalves with large load bearing ability, large flow rate, and high operational frequency are objectives of this research.

Electrically Actuated Hydraulic Solids
Advanced Engineering Materials, 2016The authors introduce a new class of electrically‐actuated soft materials. Electro‐active hydraulic solids (EAHSs) are comprised of numerous microscale phase change capsules embedded inside a conductive elastomer matrix which replicate traditional wax actuators in a massively parallel fashion.
