Besides exploring the static shape of the examined system, observing the machines' mechanics (e.g., motor-driven mechanisms) and transport routes for the material transport (e.g., via conveyor belts or chains, or rail-based transport systems) can play an equally important role in such a review. In practice it is often the case, that the relevant information about transport routes, or kinematic properties is either not consequently modeled in the CAD data or is lost during conversion processes. To significantly reduce the manual effort and costs for creating animations of the machines complex behavior with such limited input data for a design review, we present a set of algorithms to automatically determine geometrical properties of machine parts based only on their triangulated surfaces. The algorithms allow to detect the course of transport systems, the orientation of objects in 3d space, rotation axes of cylindrical objects and holes, the number of tooth of gears, as well as the tooth spacing of toothed racks. We implemented the algorithms in the VR system PADrend and applied them to animate virtual prototypes of real machines.","lang":"eng"}],"status":"public","type":"conference","publication":"Proceedings of the ASME 2017 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference, Band 1","title":"Automatic Derivation of Geometric Properties of Components from 3D Polygon Models","doi":"https://doi.org/10.1115/DETC2017-67528","conference":{"name":"Cleveland, USA, 6. - 9.

A common local model for\r\nextremely simple robots is the following: The robots do not have a common\r\ncompass, only have a constant viewing radius, are autonomous and\r\nindistinguishable, can move at most a constant distance in each step, cannot\r\ncommunicate, are oblivious and do not have flags or states. The only gathering\r\nalgorithm under this robot model, with known runtime bounds, needs\r\n$\\mathcal{O}(n^2)$ rounds and works in the Euclidean plane. The underlying time\r\nmodel for the algorithm is the fully synchronous $\\mathcal{FSYNC}$ model. On\r\nthe other side, in the case of the 2-dimensional grid, the only known gathering\r\nalgorithms for the same time and a similar local model additionally require a\r\nconstant memory, states and \"flags\" to communicate these states to neighbors in\r\nviewing range. They gather in time $\\mathcal{O}(n)$.\r\n  In this paper we contribute the (to the best of our knowledge) first\r\ngathering algorithm on the grid that works under the same simple local model as\r\nthe above mentioned Euclidean plane strategy, i.e., without memory (oblivious),\r\n\"flags\" and states. We prove its correctness and an $\\mathcal{O}(n^2)$ time\r\nbound in the fully synchronous $\\mathcal{FSYNC}$ time model.

Besides exploring the static shape of the examined system, observing the machines’ mechanics (e.g., motor-driven mechanisms) and transport routes for the material transport (e.g., via conveyor belts or chains, or rail-based transport systems) can play an equally important role in such a review. In practice it is often the case, that the relevant information about transport routes, or kinematic properties is either not consequently modeled in the CAD data or is lost during conversion processes. To significantly reduce the manual effort and costs for creating animations of the machines complex behavior with such limited input data for a design review, we present a set of algorithms to automatically determine geometrical properties of machine parts based only on their triangulated surfaces. The algorithms allow to detect the course of transport systems, the orientation of objects in 3d space, rotation axes of cylindrical objects and holes, the number of tooth of gears, as well as the tooth spacing of toothed racks. We implemented the algorithms in the VR system PADrend and applied them to animate virtual prototypes of real machines.","lang":"eng"}],"volume":1,"date_created":"2020-03-24T08:36:05Z","author":[{"first_name":"Sascha","id":"11648","full_name":"Brandt, Sascha","last_name":"Brandt","orcid":"https://orcid.org/0000-0003-3546-203X"},{"id":"146","full_name":"Fischer, Matthias","last_name":"Fischer","first_name":"Matthias"},{"last_name":"Gerges","full_name":"Gerges, Maria","first_name":"Maria"},{"first_name":"Claudius","last_name":"Jähn","full_name":"Jähn, Claudius"},{"full_name":"Berssenbrügge, Jan","last_name":"Berssenbrügge","first_name":"Jan"}],"date_updated":"2022-01-06T06:52:49Z","doi":"10.1115/detc2017-67528","conference":{"start_date":"2017-08-06","name":"37th Computers and Information in Engineering Conference","location":"Cleveland, USA","end_date":"2017-08-09"},"title":"Automatic Derivation of Geometric Properties of Components From 3D Polygon Models","publication_identifier":{"isbn":["9780791858110"]},"publication_status":"published","intvolume":"         1","page":"91:1-91:10","citation":{"bibtex":"@inproceedings{Brandt_Fischer_Gerges_Jähn_Berssenbrügge_2017, title={Automatic Derivation of Geometric Properties of Components From 3D Polygon Models}, volume={1}, DOI={<a href=\"https://doi.org/10.1115/detc2017-67528\">10.1115/detc2017-67528</a>}, booktitle={Volume 1: 37th Computers and Information in Engineering Conference}, author={Brandt, Sascha and Fischer, Matthias and Gerges, Maria and Jähn, Claudius and Berssenbrügge, Jan}, year={2017}, pages={91:1-91:10} }","mla":"Brandt, Sascha, et al. “Automatic Derivation of Geometric Properties of Components From 3D Polygon Models.” <i>Volume 1: 37th Computers and Information in Engineering Conference</i>, vol. 1, 2017, pp. 91:1-91:10, doi:<a href=\"https://doi.org/10.1115/detc2017-67528\">10.1115/detc2017-67528</a>.","short":"S.

Ein wichtiger Untersuchungsgegenstand ist dabei die Analyse von Transportwegen für den Materialtransport mittels Fließbändern, Förderketten oder schienenbasierten Transportsystemen. Diese Transportwege werden im VR-System animiert. Problematisch dabei ist, dass derartige Transportsysteme im zugrundeliegenden CAD-Modell in der Praxis oft nicht modelliert und nur exemplarisch angedeutet werden, da diese für die Konstruktion nicht relevant sind (z.B. der Fördergurt eines Förderbandes, oder die Kette einer Förderkette), oder die Informationen über den Verlauf bei der Konvertierung der Daten in das VR-System verloren gehen. Bei der Animation dieser Transportsysteme in einem VR-System muss der Transportweg also aufwändig, manuell nachgearbeitet werden. Das Ziel dieser Arbeit ist die Reduzierung des notwendigen manuellen Nachbearbeitungsaufwandes für das Design-Review durch eine automatische Berechnung der Animationspfade entlang eines Transportsystems. Es wird ein Algorithmus vorgestellt, der es ermöglicht mit nur geringem zeitlichem Benutzeraufwand den Animationspfad aus den reinen polygonalen dreidimensionalen Daten eines Transportsystems automatisch zu rekonstruieren.","lang":"ger"}],"author":[{"orcid":"https://orcid.org/0000-0003-3546-203X","last_name":"Brandt","id":"11648","full_name":"Brandt, Sascha","first_name":"Sascha"},{"last_name":"Fischer","full_name":"Fischer, Matthias","id":"146","first_name":"Matthias"}],"date_created":"2020-03-24T08:44:25Z","volume":369,"publisher":"Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn","date_updated":"2022-01-06T06:52:49Z","conference":{"name":"Wissenschaftsforum Intelligente Technische Systeme (WInTeSys) 2017","start_date":"2017-05-11","end_date":"2017-05-12","location":"Paderborn"},"title":"Automatische Ableitung der Transportwege von Transportsystemen aus dem 3D-Polygonmodell","publication_status":"published","citation":{"ama":"Brandt S, Fischer M.

Given an arbitrarily distributed (yet connected) swarm of robots, the gathering problem on the grid is to locate all robots within a 2x2- sized area that is not known beforehand. Two robots are connected if they are vertical or horizontal neighbors on the grid. The locality constraint means that no global control, no compass, no global communication and only local vision is available; hence, a robot can only see its grid neighbors up to a constant L1-distance, which also limits its movements. A robot can move to one of its eight neighboring grid cells and if two or more robots move to the same location they are merged to be only one robot. The locality constraint is the significant challenging issue here, since robot move- ments must not harm the (only globally checkable) swarm connectivity. For solving the gathering problem, we provide a synchronous algorithm { executed by every robot { which ensures that robots merge without breaking the swarm con- nectivity. In our model, robots can obtain a special state, which marks such a robot to be performing specific connec- tivity preserving movements in order to allow later merge operations of the swarm. Compared to the grid, for gath- ering in the Euclidean plane for the same robot and time model the best known upper bound is O(n^2)."}],"status":"public"},{"_id":"16360","department":[{"_id":"63"}],"user_id":"15415","language":[{"iso":"eng"}],"publication":"Proceedings of the 30th International Parallel and Distributed Processing Symposium (IPDPS)","type":"conference","abstract":[{"text":"We consider the following variant of the two dimensional gathering problem for swarms of robots: Given a swarm of n indistinguishable, point shaped robots on a two dimensional grid. Initially, the robots form a closed chain on the grid and must keep this connectivity during the whole process of their gathering. Connectivity means, that neighboring robots of the chain need to be positioned at the same or neighboring points of the grid. In our model, gathering means to keep shortening the chain until the robots are located inside a 2*2 subgrid. Our model is completely local (no global control, no global coordinates, no compass, no global communication or vision, ...). Each robot can only see its next constant number of left and right neighbors on the chain. This fixed constant is called the viewing path length. All its operations and detections are restricted to this constant number of robots. Other robots, even if located at neighboring or the same grid point cannot be detected. Only based on the relative positions of its detectable chain neighbors, a robot can decide to obtain a certain state. Based on this state and their local knowledge, the robots do local modifications to the chain by moving to neighboring grid points without breaking the chain. These modifications are performed without the knowledge whether they lead to a global progress or not. We assume the fully synchronous FSYNC model. For this problem, we present a gathering algorithm which needs linear time. This result generalizes a result, where an open chain with specified distinguishable (and fixed) endpoints is considered.

Initially, the robots form a closed chain on\r\nthe grid and must keep this connectivity during the whole process of their\r\ngathering. Connectivity means, that neighboring robots of the chain need to be\r\npositioned at the same or neighboring points of the grid. In our model,\r\ngathering means to keep shortening the chain until the robots are located\r\ninside a $2\\times 2$ subgrid. Our model is completely local (no global control,\r\nno global coordinates, no compass, no global communication or vision, \\ldots).\r\nEach robot can only see its next constant number of left and right neighbors on\r\nthe chain. This fixed constant is called the \\emph{viewing path length}. All\r\nits operations and detections are restricted to this constant number of robots.\r\nOther robots, even if located at neighboring or the same grid point cannot be\r\ndetected. Only based on the relative positions of its detectable chain\r\nneighbors, a robot can decide to obtain a certain state. Based on this state\r\nand their local knowledge, the robots do local modifications to the chain by\r\nmoving to neighboring grid points without breaking the chain. These\r\nmodifications are performed without the knowledge whether they lead to a global\r\nprogress or not. We assume the fully synchronous $\\mathcal{FSYNC}$ model. For\r\nthis problem, we present a gathering algorithm which needs linear time. This\r\nresult generalizes the result from \\cite{hopper}, where an open chain with\r\nspecified distinguishable (and fixed) endpoints is considered.","lang":"eng"}],"publication":"arXiv:1510.05454","type":"preprint","language":[{"iso":"eng"}],"department":[{"_id":"63"}],"user_id":"15415","_id":"16449","external_id":{"arxiv":["1510.05454"]},"citation":{"ama":"Abshoff S, Cord-Landwehr A, Fischer M, Jung D, Meyer auf der Heide F.
