Synthesis of rather simple behaviors such as\r\ncollision avoidance by applying artificial evolution has been shown multiple\r\ntimes. However, the difficulty of this synthesis increases heavily with\r\nincreasing complexity of the task that should be performed by the robot. We try\r\nto tackle this problem of complexity with Artificial Homeostatic Hormone\r\nSystems (AHHS), which provide both intrinsic, homeostatic processes and\r\n(transient) intrinsic, variant behavior. By using AHHS the need for pre-defined\r\ncontroller topologies or information about the field of application is\r\nminimized. We investigate how the principle design of the controller and the\r\nhormone network size affects the overall performance of the artificial\r\nevolution (i.e., evolvability). This is done by comparing two variants of AHHS\r\nthat show different effects when mutated. We evolve a controller for a robot\r\nbuilt from five autonomous, cooperating modules. The desired behavior is a form\r\nof gait resulting in fast locomotion by using the modules' main hinges.","lang":"eng"}],"status":"public"},{"title":"A Model of Symmetry Breaking in Collective Decision-Making","doi":"10.1007/978-3-642-15193-4_60","publisher":"Springer","date_updated":"2022-01-06T06:54:24Z","volume":6226,"date_created":"2020-10-29T14:22:12Z","author":[{"first_name":"Heiko","full_name":"Hamann, Heiko","last_name":"Hamann"},{"first_name":"Bernd","last_name":"Meyer","full_name":"Meyer, Bernd"},{"first_name":"Thomas","last_name":"Schmickl","full_name":"Schmickl, Thomas"},{"first_name":"Karl","last_name":"Crailsheim","full_name":"Crailsheim, Karl"}],"year":"2010","intvolume":"      6226","page":"639-648","citation":{"ama":"Hamann H, Meyer B, Schmickl T, Crailsheim K.

The classic approach of hand-coded controllers is very efficient for well-defined tasks and specific environments but poor in adapting to changing environmental conditions. One alternative approach is the application of evolutionary algorithms which need, in turn, easily evolvable representations of controllers. In this paper, we investigate one promising approach of an artificial hormone system as a control paradigm which is believed to be easily optimized by evolutionary processes. In a first step of this research, we focus on the simple task of collision avoidance. We present a brief mathematical analysis of this controller approach and an implementation of the controller on a mobile robot to check the feasibility in principle of our approach. The task is successfully accomplished and we conclude with a discussion of the hormone dynamics in the robot."}],"type":"conference","publication":"2009 IEEE/RSJ International Conference on Intelligent Robots and Systems"},{"title":"Two different approaches to a macroscopic model of a bio-inspired robotic swarm","date_created":"2020-11-02T14:07:44Z","year":"2009","issue":"9","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"By compiling macroscopic models we analyze the adaptive behavior in a swarm of autonomous robots generated by a bio-inspired, distributed control algorithm.

These two models were compared concerning their prediction quality and their analytical power: One model allowed easy identification of the major feedback loops governing the swarm behavior. The other model allowed analysis of the expected shapes and positions of observable robot clusters. We found a high correlation in the challenges posed by both modeling techniques and we highlighted the inherent problems of inferring emergent macroscopic rules from a microscopic description of swarm behavior."}],"publication":"Robotics and Autonomous Systems","doi":"10.1016/j.robot.2009.06.002","date_updated":"2022-01-06T06:54:25Z","author":[{"first_name":"Thomas","last_name":"Schmickl","full_name":"Schmickl, Thomas"},{"first_name":"Heiko","full_name":"Hamann, Heiko","last_name":"Hamann"},{"first_name":"Heinz","last_name":"Wörn","full_name":"Wörn, Heinz"},{"last_name":"Crailsheim","full_name":"Crailsheim, Karl","first_name":"Karl"}],"volume":6,"citation":{"ama":"Schmickl T, Hamann H, Wörn H, Crailsheim K.

In previous experiments, the collective behavior of 15 autonomous swarm robots, driven by a simple bio-inspired control algorithm, was investigated: in two different environmental conditions, the ability of the robots to aggregate below a light source was tested. Distinct approaches to predict the dynamics of the spatial distribution were made by two different modeling approaches: one model was constructed in a compartmental manner (ODEs). In parallel, a space-continuous model (PDEs) was constructed. Both models show a high degree of similarity concerning the modeling of concrete environmental factors (light), but due to their different basic approaches, show also significant differences in their implementation. However, the predictions of both models compare well to the observed behavior of the robotic swarm, thus both models can be used to develop further extensions of the algorithm as well as different experimental setups without the need to run extensive real robotic preliminary experiments."}],"author":[{"full_name":"Hamann, Heiko","last_name":"Hamann","first_name":"Heiko"},{"last_name":"Schmickl","full_name":"Schmickl, Thomas","first_name":"Thomas"},{"first_name":"Heinz","last_name":"Wörn","full_name":"Wörn, Heinz"},{"full_name":"Crailsheim, Karl","last_name":"Crailsheim","first_name":"Karl"}],"date_created":"2020-11-16T14:03:10Z","publisher":"IEEE Press","date_updated":"2022-01-06T06:54:26Z","doi":"10.1109/IROS.2008.4651038","title":"Spatial Macroscopic Models of a Bio-Inspired Robotic Swarm Algorithm","page":"1415--1420","citation":{"apa":"Hamann, H., Schmickl, T., Wörn, H., &#38; Crailsheim, K.

It is difficult to determine the individual robot’s behavior based on the swarm behavior and vice versa due to the high number of agent–agent interactions. A step towards a solution of this problem is the development of appropriate models which accurately predict the swarm behavior based on a specified control algorithm. Such models would reduce the necessary number of time-consuming simulations and experiments during the design process of an algorithm. In this paper we propose a model with focus on an explicit representation of space because the effectiveness of many swarm robotic scenarios depends on spatial inhomogeneity. We use methods of statistical physics to address spatiality. Starting from a description of a single robot we derive an abstract model of swarm motion. The model is then extended to a generic model framework of communicating robots. In two examples we validate models against simulation results. Our experience shows that qualitative correctness is easily achieved, while quantitative correctness is disproportionately more difficult but still possible.","lang":"eng"}],"user_id":"15415","department":[{"_id":"63"},{"_id":"238"}],"_id":"20369","language":[{"iso":"eng"}]},{"type":"conference","publication":"IEEE Swarm Intelligence Symposium, Honolulu, USA, April 1-5","status":"public","_id":"20374","user_id":"15415","department":[{"_id":"63"},{"_id":"238"}],"language":[{"iso":"eng"}],"year":"2007","citation":{"apa":"Dorigo, M., Hamann, H., Szymanski, M., Wörn, H., &#38; Shi, Y.

Predicting a system of many components with a huge amount of interactions is beyond human skills. The currently common use of simulations for design support is not satisfying, as it is time-consuming and the results are most likely sub- optimal. In this work, we present the derivation of an analytical, time-, and space-continuous model for a swarm of autonomous robots based on the Fokker-Planck equation. While the motion model is in most parts physically motivated, the communication model is based on a heuristic approach. A showcase application to a recently proposed scenario of collective perception in a huge swarm of robots with very limited abilities is given and the simulation results are compared to the model. Despite the high level of abstraction, the prediction discrepancies are small and the parameters can be mapped one-to-one from the model to the control algorithm. Finally, we give an outlook on the capabilities of the proposed model, discuss its limitations, and suggest an improvement that could reduce the number of empirically determined parameters.","lang":"eng"}],"author":[{"full_name":"Hamann, Heiko","last_name":"Hamann","first_name":"Heiko"},{"full_name":"Wörn, Heinz","last_name":"Wörn","first_name":"Heinz"}],"date_created":"2020-11-19T11:24:11Z","date_updated":"2022-01-06T06:54:27Z","doi":"10.1109/saso.2007.3","title":"A Space- and Time-Continuous Model of Self-Organizing Robot Swarms for Design Support","publication_status":"published","publication_identifier":{"isbn":["0769529062"]},"citation":{"apa":"Hamann, H., &#38; Wörn, H.
