Forward and inverse kinematics of double universal joint robot wrists [PDF]
A robot wrist consisting of two universal joints can eliminate the wrist singularity problem found on many individual robots. Forward and inverse position and velocity kinematics are presented for such a wrist having three degrees of freedom.

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide
Advanced Science, EarlyView.K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Kinematics and Workspace Analysis of a Three-Axis Parallel Manipulator: the Orthoglide [PDF]
, 2006 The paper addresses kinematic and geometrical aspects of the Orthoglide, a three-DOF parallel mechanism. This machine consists of three fixed linear joints, which are mounted orthogonally, three identical legs and a mobile platform, which moves in the ...

Advanced Science, EarlyView.Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

Advanced Science, EarlyView.Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...
