RISThe Design of Looped-Synchronous Mechanism With Duplicated Spatial Assur-Groups
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The looped-synchronous mechanism (LSM) is a special one degree-of-freedom (DOF) closed chain of transmission with a large number of duplicated units that synchronizes the motion of many output links. This kind of mechanism ...
A New Index of Static Actuation Force Sensitivity of Mechanisms Based on Unified Forward Jacobian Matrix
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel performance index, which is called static actuation force sensitivity (SAFS), to investigate the response of the actuation forces when the amplitude of the suffered load of the end-effector has ...
Singularity Loci, Bifurcated Evolution Routes, and Configuration Transitions of Reconfigurable Legged Mobile Lander From Adjusting, Landing, to Roving
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the reconfigurable legged mobile lander (ReLML) with its modes from adjusting, landing, to roving. Based on the invented metamorphic variable-axis revolute hinge, the actuated link has three alternative ...
Chasles' Motion Sphere—A Useful Tool to Visually Express the Motion Characteristics Over the Workspace of Robotic Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a useful concept/tool, i.e., Chasles' motion sphere (CMSphere), that is able to visually express the motion characteristics over the workspace and capable of investigating the local motion performance ...
Research on Curved Layer Fused Deposition Modeling With a Variable Extruded Filament
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of layered additive manufacturing (AM) limits manufactured parts, which leads to the stair-step error, support structures and the anisotropy. Curved layer fused deposition modeling (CLFDM) has been proposed by ...
Shape and Performance Controlled Advanced Design for Additive Manufacturing: A Review of Slicing and Path Planning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) brings out a revolution of how the products are designed and manufactured. To obtain desired components, advanced design for additive manufacturing (ADfAM) is widely emphasized in geometry, ...
Type Synthesis of a Family of Novel Four, Five, and Six Degrees of Freedom Sea Lion Ball Mechanisms With Three Limbs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A family of novel mechanisms with three limbs called sea lion ball mechanisms (SLBMs) is investigated that looks like a sea lion playing with a ball. The SLBMtype mechanism is composed of an upper part and a lower part ...
Novel Design of Legged Mobile Landers With Decoupled Landing and Walking Functions Containing a Rhombus Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During extraterrestrial planetary exploration programs, autonomous robots are deployed using a separate immovable lander and rover. This mode has some limitations. In this paper, a concept of a novel legged robot with ...
Novel Design and Performance Analysis of 1R1T Remote Center-of-Motion Mechanisms With Partially Decoupled T- and R-Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Remote center-of-motion (RCM) mechanisms provide a way for surgical instruments to pass through a remote center (e.g., skin incision) under geometrical constraints, facilitating safer operations in minimally invasive surgery ...
