... placement of actuators and arbitrary combinations of revolute joints and prismatic joints. A mobility analysis method is presented to analyze the system of equations, which includes the reduction phase (static link merge) and the decomposition phase (dynamic and static link merge). All findings...

Mobility Analysis of Thin-Panel Origamis Based on a Coplanar 2-Twist Screw System

Sen Wang, Hailin Huang, Bing Li, Xiaojun Yang
Journal: Journal of Mechanical Design
Publisher: ASME
Article Type: Research Papers
J. Mech. Des. November 2020, 142(11): 113302.
Paper No: MD-19-1885

...Sen Wang; Hailin Huang; Bing Li; Xiaojun Yang This paper presents an intuitive approach for mobility analysis of thin-panel origamis based on a coplanar 2-twist screw system, which consists of a pair of parallel/concurrent line vectors. In this study, we first proved that in any thin-panel origami...
