On Computational Study of Embodiment: Some Remarks and an Example

Eco-grammar (EG-) systems are proposed as an example of a suitable formal framework for the study of some of the computationally relevant properties of the behavior of collections of embodied agents -- called herds in this article -- sharing a common environment, and acting in it in simple ways

Some Questions Inspired by (Membrane Computing Motivated) Language-Theoretic Models

This contribution argues for the proposition that formal models based on the theory of formal grammars and languages are adequate for the study of some computationally relevant properties of agents and multi-agent systems. Some questions are formulated concerning the possibilities to enlarge the universality and realism of such models by considering the possibilities to go with their computing abilities beyond the traditional Turing-computability, and by considering very natural properties of any real (multi-)agent system such as the partially predictable functioning (behavior) of agents, their unreliability, dysfunctions, etc

A Note on Emergence in Multi-Agent String Processing Systems

We propose a way to define (and, in a certain extent, even to measure) the phenomenon of emergence which appears in a complex system of interacting agents whose global behaviour can be described by a language and whose components (agents) can also be associated with grammars and languages. The basic idea is to identify the "linear composition of behaviours" with "closure under basic operations", such as the AFL (Abstract Families of Languages) operations, which are standard in the theory of formal languages

Implementing Obstacle Avoidance and Follower Behaviors on Koala Robots Using Numerical P Systems

Membrane controllers have been developed using Numerical P Systems and their extension, Enzymatic Numerical P Systems, for controlling mobile robots like e- puck and Khepera III. In this paper we prove that membrane controllers can be easily adapted for other types of robotic platforms. Therefore, obstacle avoidance and follower behaviors were adapted for Koala robots. The membrane controllers for Koala robots have been tested on real and simulated platforms. Experimental results and performance analysis are presented
