Phenomenology of reaction-diffusion binary-state cellular automata (2006)
Journal Article
We study a binary-cell-state eight-cell neighborhood two-dimensional cellular automaton model of a quasi-chemical system with a substrate and a reagent. Reactions are represented by semitotalistic transitions rules: every cell switches from state 0 t... Read More about Phenomenology of reaction-diffusion binary-state cellular automata.
Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium (2005)
Journal Article
We experimentally demonstrate that excitation wave-fragments in a Belousov-Zhabotinsky (BZ) medium with immobilised catalyst can be used to build elementary logical gates and circuits. Following our previous theoretical constructions [Adamatzky A. Co... Read More about Experimental implementation of collision-based gates in Belousov-Zhabotinsky medium.
Experimental implementation of mobile robot taxis with onboard Belousov-Zhabotinsky chemical medium (2004)
Journal Article
We discuss the first-ever experimental realization of the onboard excitable chemical controller for stimulus-guided navigation of mobile robots. We demonstrate that the Belousov-Zhabotinsky (BZ) reaction in the form of an onboard thin layer chemical...

Reaction-diffusion navigation robot control: From chemical to VLSI analogic processors (2004)
Journal Article
We introduce a new methodology and experimental implementations for real-time wave-based robot navigation in a complex, dynamically changing environment. The main idea behind the approach is to consider the robot arena as an excitable medium, in whic...

Experimental reaction-diffusion chemical processors for robot path planning (2003)
Journal Article
In this paper we discuss the experimental implementation of a chemical reaction-diffusion processor for robot motion planning in terms of finding the shortest collision-free path for a robot moving in an arena with obstacles. These reaction-diffusion... Read More about Experimental reaction-diffusion chemical processors for robot path planning.
Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond (2002)
Journal Article
We exploit the particulars of diffusive wave front interactions in certain types of two-reactant reaction-diffusion medium to construct a laboratory prototype of an XOR gate. In the design, the values of the logic variables are represented by the pre... Read More about Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond.
Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton (2002)
Journal Article
We offer a new approach to computing a shortest collision-free path in a space containing obstacles, using an experimental chemical processor, based on the Belousov-Zhabotinsky (BZ) reaction. The chemical processor was then coupled via optical links... Read More about Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton.
Experimental reaction-diffusion pre-processor for shape recognition (2002)
Journal Article
We have produced an experimental implementation of a massively-parallel reaction-diffusion processor which performs one of the most essential parts of shape recognition - construction of a skeleton. A skeleton is a unique, stable and invariant repres... Read More about Experimental reaction-diffusion pre-processor for shape recognition.
On loading slime mould Physarum polycephalum with metallic particles
Journal Article
Plasmodium \emph{Physarum polycephalum} is a large single cell visible with the naked eye. When inoculated on a substrate with attractants and repellents the plasmodium develops optimal networks of protoplasmic tubes which span sites of attractants (...

Spontaneous bursting spike patterns seen in simple three memristor circuits
Journal Article
The distinctive switching spikes seen in single memristors are suppressed in networks of memristors. Instead oscillatory behaviour interrrupted by spontaneous irregular bursting spike patterns are seen. An investigation of two and three memrisor circ...
