Open AccessToward a theory of collective resource distribution: a study of a dynamic morphogenesis controller
Nature has various approaches to manage the collective distribution of resources. The division of a honeybee colony into subgroups, the formation of ant trails to food sources, and the spread of tree branches ...

Adaptive Path Formation in Self-Assembling Robot Swarms by Tree-Like Vascular Morphogenesis
For self-assembly, robot swarms can be programmed to form predefined shapes. However, if the swarm is required to adapt the assembled shapes to dynamic features of the environment at runtime, then the shapes’ ...

Morphogenesis as a Collective Decision of Agents Competing for Limited Resource: A Plants Approach
Competition for limited resource is a common concept in many artificial and natural collective systems. In plants, the common resources – water, minerals and the products of photosynthesis – are a subject of c...

Evolving Controllers for Programmable Robots to Influence Non-programmable Lifeforms: A Casy Study
In this paper, a decentralized reaction-diffusion-based controller is evolved for a set of robots in an arena interacting with two simulated juvenile bees as non-programmable agents. The bees react to the stim...

Potential of Heterogeneity in Collective Behaviors: A Case Study on Heterogeneous Swarms
Research in swarm robotics and collective behaviors is often focused on homogeneous swarms. However, heterogeneity in behaviors can be advantageous as we know, for example, from studies on social insects. Our ...

Sensor-Coupled Fractal Gene Regulatory Networks for Locomotion Control of a Modular Snake Robot
In this paper we study fractal gene regulatory network (FGRN) controllers based on sensory information. The FGRN controllers are evolved to control a snake robot consisting of seven simulated ATRON modules. Ea...

An alternative representation of Fractal Gene Regulatory Networks facilitating analysis and interpretation
This paper introduces a new representation of Fractal Gene Regulatory Networks (FGRNs) that facilitates analysis and interpretation of their internal mechanisms. FGRNs are demonstrated to be useful tools in so...

Evolving Reactive Controller for a Modular Robot: Benefits of the Property of State-Switching in Fractal Gene Regulatory Networks
In this paper, we study Fractal Gene Regulatory Networks (FGRNs) evolved as local controllers for a modular robot in snake topology that reacts adaptively to environment. The task is to have the robot moving i...

Fractal Gene Regulatory Networks for Robust Locomotion Control of Modular Robots
Designing controllers for modular robots is difficult due to the distributed and dynamic nature of the robots. In this paper fractal gene regulatory networks are evolved to control modular robots in a distribu...
