Chapter
Full-text available
Robotic manipulators play an important role in space exploration and pave the way for satellite lifetime extensions, orbital asset inspections, and deorbiting. However, space robots are tested in Earth’s gravity although they are designed for zero gravity. The joints are limited in the torque which might be below of what is necessary to move on gro...

Robotic manipulators play a pivotal role in space explo- ration and pave the way for satellite lifetime extensions, orbital asset inspections, and deorbiting. However, space robots are tested under Earth’s gravity despite being de- signed for zero gravity. Most space robots are constructed such that they cannot bear the Earth’s gravitational loads,...
Conference Paper
In einem vom Ministerium für Heimat, Kommunales, Bau und Digitalisierung des Landes Nordrhein-Westfalen geförderten Projekt soll die Digitalisierung in der Bauwirtschaft vorangetrieben werden. Das Ziel ist es, wesentliche Teile des Rohbaus auf Basis eines digitalen Gebäudemodells automatisch mit parallelen Seilrobotern zu errichten. Nach der Realis...
Article
Full-text available
This paper outlines an important step in characterizing a novel field of robotic construction research where a cable-driven parallel robot is used to extrude cementitious material in three-dimensional space, and thus offering a comprehensive new approach to computational design and construction, and to robotic fabrication at larger scales. Develope...
Article
Seilroboter stellen einen innovativen und vielversprechenden Ansatz bei der Digitalisierung und Automatisierung im Mauerwerksbau dar. Zudem verfügen sie über das Potenzial, die Verarbeitung von Mauersteinen zu revolutionieren. Denn der Einsatz von Seilrobotern eröffnet die Möglichkeit, große Bauvolumina auch bei komplexen Geometrien und reduziertem...
Chapter
This paper presents a new method for cable-driven parallel robots (CDPR) to generate point-to-point (PTP) trajectories with the consideration of CDPR workspace. Similar to existing trajectory planners that work on position level using a quintic or higher polynomial, here the complete acceleration process is planned referring to a double-S trajector...
Chapter
The construction industry is still dominated by manual processes. This is both due to conventional planning tools that do not allow for a complete digital representation of a building and the limitation of the workspace of conventional robots that is far below the dimensions of most buildings. With the introduction of Building Information Modeling...
