Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

About the SBRA Method Applied in Mechanics of Continental Plates [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 This article shows how the probabilistic SBRA (Simulation-Based Reliability Assessment) Method (i.e. stochastic Monte Carlo approach) is applied to the model of the behaviour of the lithosphere of the Earth (geomechanical model).

A Transnasal Endoscope for Robotically Assisted Gastroscopy
Advanced Robotics Research, EarlyView.This work introduces a 4.25 mm diameter magnetically navigated transnasal endoscope for upper gastrointestinal (GI) screening and intervention. The system enables precise remote steering throughout the upper GI tract and is demonstrated through in vitro and in vivo experiments, including the robotic execution of preprogrammed retroflexions, trans ...

Advanced Science, EarlyView.A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

ISSUES RELATED TO RATCHETING IN PIPING COMPONENTS [PDF]
, 1999 PresentationMaterial and piping component test data involving ratcheting are discussed in regards to the phenomenon of shakedown. The data set studied indicates that the general belief about the occurrence of shakedown after a few cycles of ratcheting ...

Evolution of Physical Intelligence Across Scales
Advanced Intelligent Discovery, EarlyView.By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Self-loosening behavior of bolt in curvic coupling due to materials ratcheting at thread root
Advances in Mechanical Engineering, 2019 This article presents the bolt self-loosening mechanism in curvic coupling due to the structural ratcheting under cyclic loading. Finite element simulations are carried out under several loading conditions with different preloads and cyclic torque ...
