Parametric study on the cylindrical roller enveloping end-face internal engagement worm gear
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 A novel worm gear named cylindrical roller enveloping end-face internal engagement worm gear is originally proposed for the first time in this study. Also, the meshing functions including induced normal curvature and lubrication angle are derived based ...

Advanced Science, EarlyView.A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics
Advanced Intelligent Systems, EarlyView.Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.
