A Quadruped Piezoelectric Ultrasonic Actuating Robot with Foot‐Leg‐Trunk‐Integrated Structure
Advanced Robotics Research, EarlyView.This study proposes a novel foot‐leg‐trunk‐integrated quadruped piezoelectric ultrasonic actuating robot with small size and lightweight. A hybrid vibration mode combining the first‐order out‐of‐plane bending vibration of the trunk and the first‐order horizontal bending vibration of driving legs is designed to generate elliptical trajectories at foot ...

Bounds and compactness for solutions of second-order elliptic equations
Electronic Journal of Differential Equations, 2012 In this article, we establish some connections between Sobolev spaces and nonlinear singular elliptic problems, to obtain bounds and compactness results for solutions of second-order elliptic equations.

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping
Advanced Robotics Research, EarlyView.This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Advanced Theory and Simulations, EarlyView.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the
