Structural Design and Performance Analysis of Novel Torsional Impact Tool
Shiyou jixie, 2017 The existing impact and rotary-impact rock breaking technology mostly use the axial impact and the shear action of the PDC bit to achieve high-efficiency rock breaking, but excessive axial force will cause the failure of PDC bit shear force, resulting in

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

A digital twin for torsional vibrations of power plant turbogenerators
Turbogenerators are important mechanical and electrical components in power plants. The steam turbines convert thermal energy into mechanical energy causing the rotor to spin. And the generator produces electrical energy by electromechanical interactions.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots
Advanced Robotics Research, EarlyView.This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

A sequence environment modulates the impact of methylation on the torsional rigidity of DNA
Chemical Communications, 2018 We explain, with atomic-level detail, how DNA methylation may contribute to the regulation of biological processes. We show that DNA sequence environment modulates the impact of methylation on the physical properties of the double helix.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation
Advanced Robotics Research, EarlyView.A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.
