Flexible-body Modeling, Kinematic Identification, and Assembly Accuracy of Overconstrained Spatial Linkages
Daniel Huczala, Michael Pieber, Johannes Gerstmayr +6
Overconstrained rational single-loop linkages are efficient, compact, and low-cost custom mechanisms, yet their deployment in industrial settings is limited. In simulations, rigid…
Bistable Quad-Nets Composed of Four-Bar Linkages
Gudrun Szewieczek, Daniel Huczala, Martin Pfurner +1
We study a novel type of mechanical structures, composed of spatial four-bar linkages, that are bistable, that is, they allow for two distinct configurations. These structures have…
Shared Representation for 3D Pose Estimation, Action Classification, and Progress Prediction from Tactile Signals
Isaac Han, Seoyoung Lee, Sangyeon Park +4
Estimating human pose, classifying actions, and predicting movement progress are essential for human-robot interaction. While vision-based methods suffer from occlusion and privacy…
Computer-Aided Design of Rational Motions for 4R and 6R Spatial Mechanism Synthesis
Daniel Huczala, Severinas Zube, Martin Pfurner +2
This paper focuses on geometric methods for generating rational motions used in the design of single-loop rational linkages, 1-degree-of-freedom mechanisms that can execute prescri…
Rational Linkages: From Poses to 3D-printed Prototypes
Daniel Huczala, Johannes Siegele, Daren A. Thimm +2
In this paper, a set of tools is introduced that simplifies the synthesis and rapid-prototyping of single-loop rational kinematic chains. It allows the user to perform rational mot…
An Overconstrained Vertical Darboux Mechanism
Johannes Siegele, Martin Pfurner
In this article, we will construct an overconstrained closed-loop linkage consisting of four revolute and one cylindrical joint. It is obtained by factorization of a prescribed ver…
A Multi-Bennett 8R Mechanism Obtained From Factorization of Bivariate Motion Polynomials
Johanna Frischauf, Martin Pfurner, Daniel F. Scharler +1
We present a closed-loop 8R mechanism with two degrees of freedom whose motion exhibits curious properties. In any point of a two-dimensional component of its configuration variety…
An Automated Conversion Between Selected Robot Kinematic Representations
Daniel Huczala, Tomáš Kot, Jakub Mlotek +2
This paper presents a methodology that forms an automated tool for robot kinematic representation conversion, called the RobKin Interpreter. It is a set of analytical algorithms th…
Analysis of a 3-RUU Parallel Manipulator
Thomas Stigger, Johannes Siegele, Daniel F. Scharler +2
The aim of this paper is to give a detailed examination of the input and output singularities of a 3-RUU parallel manipulator in the translational operation mode. This task is achi…
Factorization of Dual Quaternion Polynomials Without Study's Condition
Johannes Siegele, Martin Pfurner, Hans-Peter Schröcker
In this paper we investigate factorizations of polynomials over the ring of dual quaternions into linear factors. While earlier results assume that the norm polynomial is real ("mo…
Space Kinematics and Projective Differential Geometry Over the Ring of Dual Numbers
Johannes Siegele, Hans-Peter Schröcker, Martin Pfurner
We study an isomorphism between the group of rigid body displacements and the group of dual quaternions modulo the dual number multiplicative group from the viewpoint of differenti…
