RISModeling and Experimental Validation of Actuating a Bistable Buckled Beam Via Moment Input
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bistable mechanisms have two stable equilibrium positions separated by a higher energy unstable equilibrium position. They are well suited for microswitches, microrelays, and many other macroand microapplications. This ...
An Analytical Model for Calculating the Workspace of a Flexure Hexapod Nanopositioner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analytical model for calculating the workspace of a flexurebased hexapod nanopositioner previously built by the National Institute of Standards and Technology (NIST). This nanopositioner is capable ...
A Compliant Hinge Joint Driven by the PneuNets Bending Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While soft robots enjoy the benefits of high adaptability and safety, their inherent flexibility makes them suffer from low load-carrying capacity and motion precision, which limits their applications to a broader range ...
A Three Spring Pseudorigid Body Model for Soft Joints With Significant Elongation Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compliant mechanisms achieve motion utilizing deformation of elastic members. However, analysis of compliant mechanisms for large deflections remains a significant challenge. In this paper, a threespring revolute–prism ...
Extension Effects in Compliant Joints and Pseudo Rigid Body Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compliant members come in a variety of shapes and sizes. While thin beam flexures are commonly used in this field, they can be replaced by soft members with lower aspect ratio. This paper looks to study the behavior of ...
A High Performance Pneumatically Actuated Soft Gripper Based on Layer Jamming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents a novel soft robotic gripper with a high payload capacity based on the layer jamming technology. Soft robots have a high adaptability, however suffer a low payload capacity. To overcome these conflicting ...
Modeling and Optimization of Caliber Rolling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In practice of caliber rolling, it is highly desirable to obtain optimal processing parameters to achieve the best quality in a short time. A sophisticated and faster simulation model of caliber ...
A Versatile 3R Pseudo-Rigid-Body Model for Initially Curved and Straight Compliant Beams of Uniform Cross Section
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rigid-body discretization of continuum elements was developed as a method for simplifying the kinematics of otherwise complex systems. Recent work on pseudo-rigid-body (PRB) models for compliant mechanisms has opened up ...
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 ...
Pseudorigid Body Models of Compliant DNA Origami Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we introduce a strategy for the design and computational analysis of compliant DNA origami mechanisms (CDOMs), which are compliant nanomechanisms fabricated via DNA origami selfassembly. The rigid, compliant, ...
