The Information-Cost-Reward framework for understanding robot swarm foraging

Multi-agent systems AI Date: 24/11/2017 :: 0 comments

The Information-Cost-Reward (ICR) framework relates the way in which robots obtain and share information about where work needs to be done to the swarm’s ability to exploit that information in order to perform work efficiently in the context of a particular task and environment.

Behaviour-Data Relations Modelling Language For Multi-Robot Control Algorithms

Multi-agent systems AI Date: 20/09/2017 :: 0 comments

Behaviour-Data Relations Modeling Language (BDRML) explicitely represents behaviours and data that robots utilise, as well as relationships between them. This allows BDRML to express control algorithms where robots cooperate and share information with each other while interacting with the environment.

Robot swarms in action

Multi-agent systems Robots AI Date: 28/06/2017 :: 0 comments

Watch e-puck robots collect resources and bring them back to base. While the previous simulation work helped us to learn a lot about the advantages and disadvantages of communication in swarms, doing similar experiments with real robots is already revealing interesting new things.

Book Review: Waking, Dreaming, Being

Mind AI Date: 02/04/2016 :: 0 comments

What is the self? Is it the basic nature of the mind or is it something perceived by the mind? I'd really recommend the book to anyone interested in these questions, either from a scientific or a philosophical perspective.

Lots of Robots at IROS in Germany

Robots Neural networks AI A-Life Date: 05/10/2015 :: 0 comments

I have just returned from the IROS conference that took place in Hamburg, Germany. The conference name stands for Intelligent Robots and Systems and it was a huge event full of talks and exhibitions about robotics. While the atmosphere was very professional, the spirit of Oktoberfest, a traditional German celebration of beer and German culture that happens between September and October, managed to blend in very well.

I had the privilege to present The Hive Mind, my new sci-fi puzzle game about insect-inspired construction with robots, at the University of Southampton Science and Engineering day last weekend. A lot of people came to play it and it was great to watch how they interacted with it - kids were often better at the game than their parents!

How will artificial life impact the future?

Multi-agent systems Robots Neural networks AI A-Life Date: 26/10/2014 :: 0 comments

In 2013, I was a part of the TRUCE workshop at the Alife conference. The workshop brought together scientists and creative writers in order to create a cool book full of stories about A-life (artificial life) and artificial intelligence and about how it will impact our society in the future. As I am very interested in swarm robotics, sci-fi games and movies and generally how the future will look like when robots run around and are part of our everyday lives, I jumped at the opportunity to cooperate on the project.

Stardust Colonies

Impressions from ALIFE 14 New York

Multi-agent systems Robots AI A-Life Date: 12/08/2014 :: 0 comments

This summer, I attended the Artificial Life conference in New York. There were some interesting and not-so-interesting talks, but generally I am very glad I went. I had a chance to meet some great people and more importantly, to get much needed feedback on my own research. I also got offered to try out real robots in my research.

Stardust Colonies Resurrected

I've been up to a lot lately, getting back to my Stardust Colonies game project. Some might remember that I released a demo about one and half years ago. I managed to get a lot of useful feedback for the game and I am now ready to take the development to the next level.

Ilidian the robotic dinosaur

Robots AI A-Life Date: 28/01/2014 :: 0 comments

Meet Ilidian, my robotic dinosaur pet. He is a male Pleo rb, in my opinion one of the most advanced home robotic pets at the moment. He has a lot of touch sensors so he can feel being stroked or hit on various parts of his body, temperature sensors that allow him to feel dizzy when hot or shiver when cold and much more stuff that make him quite life-like.

Stardust Colonies Web Site Is Launched!

Multi-agent systems Games C++ AI Date: 31/05/2013 :: 0 comments

I have finally launched web site for my strategy game Stardust Colonies. Unlike in most strategy games, you get to control minions who have their job preferences and will behave differently based on what you tell them to do. Also, you don't train units in buildings but clone existing ones, which I think feels more natural to the player...

Foraging Strategies in Nature and Their Application to Swarm Robotics

Multi-agent systems AI A-Life Date: 22/03/2013 :: 0 comments

While foraging is a task often experimented with in swarm robotics, it is often the case that foraging strategies inspired by nature are chosen without careful consideration. Foraging strategies including solitary foraging, behavioural matching, stigmergy, signaling to guide others and coordinated and cooperative hunting are identified and their implementation costs in robots, as well as their suitability for different scenarios is discussed.

Boid Game-Playing through Randomised Movement

Multi-agent systems Java AI A-Life Date: 22/10/2012 :: 0 comments

The original boid flocking algorithm is extended by adding randomised movement to the flock members. This approach is a light-weight alternative to other ‘follow the leader’ techniques implemented in order to create a ‘game-playing’ behaviour during which a flock changes its movement direction as observed in real birds.

Designing Robot Swarms

This project looks at the challenges involved in modeling, understanding and designing of multi-robot systems.

Robustness in Foraging E-puck Swarms Through Recruitment

Swarms of five e-puck robots are used in a semi-virtual environment, facilitated by the VICON positioning system. Recruitment can make swarms more robust to noise in robot global positioning data.

Information Flow Regulation in Preferentially Foraging Swarms

Swarms are tasked with foraging from multiple sources in dynamic environments where source locations change periodically. Preferential foraging leads to a better swarm performance, provided that information flow among robots, that results from recruitment, is regulated

Citations count fails to measure the impact of research

Academic career progress is often judged by so-called "h-index", that measures how much your research is being cited. I recently had a detailed look at what exactly the citations, specifically those reported by Google Scholar, amount to. Only a relatively small fraction of the reported citations corresponded to research being applied or reproduced in a meaningful way.
