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…
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…
The Kinematic Image of RR, PR, and RP Dyads
Tudor-Dan Rad, Daniel F. Scharler, Hans-Peter Schröcker
We provide necessary and sufficient conditions for admissible transformations in the projectivised dual quaternion model of rigid body displacements and we characterise constraint…
