This simulation is based on a computational model of several sumo fighters, which physically interact while trying to move the opponent out of the arena (lost fight). The problem is optimized using a genetic algorithm (GA), where the capabilities of not only one particular robot but of all robots simultaneously are improved. In this particular problem setup, the problem definition changes depending on the optimization path, because all robots also get better, competing against each other. The influence of different operators of the GA is investigated and compared. This paper raises the questions, which genetically controlled capabilities (e.g. size, speed) are dominant over time and how they can be identified by a sensitivity analysis using a GA. The results shed light on which parameters are dominant. This experiment typically opens up interesting fields of further research, especially about how to address optimization problems, where the optimization process influences the search space and how to eliminate the factor of randomness.04B - Beitrag KonferenzschriftPublikation Optimization of a robotic manipulation path by an evolution strategy and particle swarm optimization(2020) Murillo, Francis; Neuenschwander, Tobias; Dornberger, Rolf; Hanne, Thomas04B - Beitrag KonferenzschriftPublikation Improved long-short term memory U-Net for image segmentation(Springer, 2021) Oller, Heide; Dornberger, Rolf; Hanne, Thomas; Thampi, Sabu M.; Krishnan, Sri; Hegde, Rajesh M.; Ciuonzo, Domenico; Hanne, Thomas; Kannan R., Jagadeesh04B - Beitrag KonferenzschriftPublikation Investigating the effects of gaze behavior on the perceived delay of a robot's response(2019) Zhong, Jia; Schmiedel, Theresa; Dornberger, Rolf; Salichs, Miguel A.; Ge, Shuzhi Sam; Ivanova Barakova, Emilia; Cabibihan, John-John; Wagner, Alan R.; Castro-González, Álvaro; He, HongshengSlow responses of social robots cause user frustration in human robot communication. This paper investigates how far the gaze behavior of a robot, meaning the way the robot looks at its conversation partner, influences the perceived delay of a robot’s response in human-robot conversations. To enhance a natural conversation pattern, a gaze behavior was designed and implemented into a humanoid robot. A within-subject experiment involving 31 test subjects was designed with two conditions (with and without gaze behavior). The results generally show a positive correlation between the gaze behavior that the robot exhibits and the perceived responsiveness of the robot (in the condition with gaze behavior). However, the perceived responsiveness is the same in both conditions. One reason for this finding may be that the response time of the robot might have been generally too short to identify an effect in the experi mental setting. Future research can directly build on our research to assess the relation between gaze behavior and perceived responsiveness in further detail and draw upon the finding that gaze behavior generally plays an important role with regard to the perceived responsiveness of a robot. Robot designers can also build on our research and consider both gaze behavior and additional factors to address a perceived delay in a robot’s response.04B - Beitrag KonferenzschriftPublikation Parameter selection for ant colony optimization for solving the travelling salesman problem based on the problem size(2021) Kempter, Philipp; Schmitz, Martin Peter; Hanne, Thomas; Dornberger, Rolf; Abraham, Ajith; Hanne, Thomas; Castillo, Oscar; Gandhi, Niketa; Nogueira Rios, Tatiane; Hong, Tzung-Pei04B - Beitrag KonferenzschriftPublikation Comparison of swarm and graph algorithms for solving travelling salesman problems(2020) Eggenschwiler, Stefan; Spahic, Maja; Hanne, Thomas; Dornberger, Rolf04B - Beitrag KonferenzschriftPublikation Augmented reality to complement printed guidebooks with dynamic information: a case study in planning a climbing tour(2020) Sulger, Mathias; Korkut, Safak; Dornberger, Rolf04B - Beitrag Konferenzschrift
