RISA Mobile Bennett Network Constructed With Identical Square Panels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mobile networks, constructed with simple linkages by tessellation, have great application potential in engineering as they could change their shapes according to the need of working state by one degree-of-freedom (DOF). ...
Cyclic Behavior of Fiber-Reinforced Calcareous Sand in Acidic Environments
Publisher: American Society of Civil Engineers
Abstract: AbstractCalcareous sand contains massive shell fragments and is prone to liquefaction during
seismic events. In this study, a series of cyclic simple shear tests were conducted
to investigate the influences of acidic ...
A Reconfigurable 6R Linkage With Six Motion Modes and Three Topological Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new reconfigurable 6R linkage is obtained by combining two identical equilateral Bennett linkages arranged in a planesymmetric manner, and a detailed kinematic analysis is conducted which shows that there ...
A Comprehensive Micro-Milling Force Model for a Low-Stiffness Machining System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro-milling is widely used in various crucial fields with the ability of machining micro- and meso-scaled functional structures on various materials efficiently. However, the micro-milling force model is not comprehensively ...
A Novel Variable Stiffness Compliant Robotic Gripper Based on Layer Jamming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a novel compliant robotic gripper with three variable stiffness fingers. While the shape morphing of the fingers is cable-driven, the stiffness variation is enabled by layer jamming. The inherent ...
Evolution Design of Multiple Metamorphic Mechanisms Inspired by the Concept of Assur Group
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metamorphic mechanisms that can adapt to a variety of working conditions with distinct configurations, have gained widespread attention in recent years. However, it's always difficult to design metamorphic mechanisms with ...
Global-Position Tracking Control for Multi-Domain Bipedal Walking With Underactuation1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate control of a humanoid robot's global position (i.e., its three-dimensional (3D) position in the world) is critical to the reliable execution of high-risk tasks such as avoiding collision with pedestrians in a ...

A Novel One-Degree-of-Freedom Deployable Structure and Its Plate Form
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Deployable structures are widely utilized in various fields due to their ability to switch between a deployed working state and a folded storage state. This paper presents a new method for achieving plate forms in deployable ...
Global-Position Tracking Control for Three-Dimensional Bipedal Robots Via Virtual Constraint Design and Multiple Lyapunov Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A safety-critical measure of legged locomotion performance is a robot's ability to track its desired time-varying position trajectory in an environment, which is herein termed as “global-position tracking.” This paper ...
