Design and Modelling of a Two-Axis Compliant Joint Based on Flexure Leaf Springs
MachinesIn the field of parallel robots, traditional rigid joints compromise motion accuracy owing to inherent friction and backlash, thus driving the demand for high-performance compliant joints.

The Anatomical Record, Volume 309, Issue 9, Page 2476-2486, September 2026.Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Actuation Strategies for Underwater Jet‐Propelled Soft Robots
Journal of Field Robotics, Volume 43, Issue 6, Page 3868-3892, September 2026.ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Ultrasonographic examination of joints, a revolution in equine locomotor pathology [PDF]
Bulletin de l'Académie Vétérinaire de France, 2009 L’échographie des articulations, une révolution en pathologie locomotrice équine. D’abord utilisée pour le diagnostic et la documentation des lésions tendineuses, l'échographie est devenue depuis 1990 un complément indispensable à la radiologie dans le diagnostic des affections articulaires chez le cheval.

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)
Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.ABSTRACT Background Conventional laparoscopic instruments provide limited dexterity in confined anatomical environments, whereas existing articulated designs rely on complex rigid joints or motorised actuation, increasing mechanical complexity and limiting miniaturisation.

Closed linkages with six revolute joints
, 2016 In this dissertation, we explore spatial overconstrained closed linkages with six revolute joints and a single-degree-of-freedom (6R linkages). The first 6R linkage was invented by Pierre Frédéric Sarrus in 1853. In the literature, a lot of 6R linkages were found by numerous methods. New 6R linkages are still being found by new methods, too.

Inverse Kinematics of a Serial Manipulator with a Free Joint for Aerial Manipulation
Applied SciencesIn Aerial Manipulation, the motion of the robotic arm can cause unwanted movements of the flying base affecting the trajectory tracking capability. A possible solution to reduce these disturbances is to use a free revolute joint between the flying base ...

Analysis of Kinematics of Mechanisms Containing Revolute Joints
Kinematics of rigid bodies can be analyzed in many different ways. The advantage of using Euler parameters is that the resulting equations are polynomials and hence computational algebra, in particular Gröbner bases, can be used to study them. The disadvantage of the Gröbner basis methods is that the computational complexity grows quite fast in the ...

Effects of realistic sheep elbow kinematics in inverse dynamic simulation.
PLoS ONE, 2019 Looking for new opportunities in mechanical design, we are interested in studying the kinematic behaviour of biological joints. The real kinematic behaviour of the elbow of quadruped animals (which is submitted to high mechanical stresses in comparison ...
