Our recent Physical Review E paper about a model describing house-hunting honeybees has been selected as Research Highlight in Nature Physics. To read the Highlight please follow this link.
Our recent paper on decision making in honeybees has been selected to be an Editor’s Suggestion in Physical Review E. The journal prominently lists a small number of Physical Review E papers that the editors and referees find of particular interest, importance, or clarity. Here is a
link to the paper. You can also find the paper in the Publications section.
The DiODe team organises a minisymposium at the Mathematical Models in Ecology and Evolution conference taking place in London this July. In this minisymposium, recent progress on collective behaviour and decision making will be discussed by a selection of excellent speakers.
Two new papers with results of the DiODe project have been accepted recently. The review article entitled Collective Decision Making, which appeared in the journal Current Opinion in Behavioural Sciences, summarises recent progress in natural and artificial collective decision making. The other paper entitled A model of the best-of-N nest-site selection process in honeybees has been accepted for publication in Physical Review E and generalises in a theoretical study the nest site selection of honeybees to three and more options.
Salah Talamali joins the DiODe team beginning of May 2017 to investigate heterogeneities in collective decision making. His PhD project will involve the development of decision making algorithms and their implementation on the Kilobot platform, bringing the state of the art of artificial decision making closer to studying real-world scenarios using a swarm of robots.
Another way to get into the Spirit of Christmas. Enjoy!
A swarm of 150 kilobot robots takes a value-sensitive decentralised decision between two options (red and blue). The swarm must select the best quality option if the quality is higher than a given threshold (in this study, greater than 1.5). In this experiment, the options have quality v=5 thus the swarm makes a decision for the option blue.
The overlaying coloured circles show the two options localised in the environment. The options are signalled through two static kilobot robots acting as beacons that send infrared messages with the option’s ID and quality. The robots light up their LED in a colour that corresponds to their internal commitment state: green for the uncommitted state and red and blue for commitment to the option of the respective colour.

Chelsea Sabo and Alex Cope who were previously working on the Green Brain project have joined the DiODe project to help building a smart arena for the 900 Kilobots we have at Sheffield Robotics.
Aldo Encarnacion joined the DiODe team to work on the mathematical modelling of cellular decision making. The main part of his PhD project will involve the development of a theory that understands metabolic pathways in terms of decision making strategies.
The progress of the DiODe project can now be followed up on Youtube. Below you see a video which shows the initial state of setting up a tracking system for the Kilobots, the micro-robots we use to investigate consensus decision-making experimentally.
In the future we will post new videos that show the Kilobots in action. At the same time we want to use the DiODe Youtube channel to document the project’s chronology.
