When less is more: Robot swarms adapt better to changes with constrained communication

MS Talamali, A Saha, JAR Marshall, A Reina - Science Robotics, 2021 - science.org
To effectively perform collective monitoring of dynamic environments, a robot swarm needs
to adapt to changes by processing the latest information and discarding outdated beliefs. We …

Effect of swarm density on collective tracking performance

HL Kwa, J Philippot, R Bouffanais - Swarm Intelligence, 2023 - Springer
How does the size of a swarm affect its collective action? Despite being arguably a key
parameter, no systematic and satisfactory guiding principles exist to select the number of …

Cross-inhibition leads to group consensus despite the presence of strongly opinionated minorities and asocial behaviour

A Reina, R Zakir, G De Masi, E Ferrante - Communications Physics, 2023 - nature.com
Strongly opinionated minorities can have a dramatic impact on the opinion dynamics of a
large population. Two factions of inflexible minorities, polarised into two competing opinions …

Robot swarms break decision deadlocks in collective perception through cross-inhibition

R Zakir, M Dorigo, A Reina - International Conference on Swarm …, 2022 - Springer
We study how robot swarms can achieve a consensus on the best among a set of n possible
options available in the environment. While the robots rely on local communication with one …

Coherent collective behaviour emerging from decentralised balancing of social feedback and noise

I Rausch, A Reina, P Simoens, Y Khaluf - Swarm Intelligence, 2019 - Springer
Decentralised systems composed of a large number of locally interacting agents often rely
on coherent behaviour to execute coordinated tasks. Agents cooperate to reach a coherent …

Do we run large-scale multi-robot systems on the edge? More evidence for two-phase performance in system size scaling

J Kuckling, R Luckey, V Avrutin, A Vardy… - … on Robotics and …, 2024 - ieeexplore.ieee.org
With increasing numbers of mobile robots arriving in real-world applications, more robots
coexist in the same space, interact, and possibly collaborate. Methods to provide such …

Miscommunication between robots can improve group accuracy in best-of-n decision-making

R Zakir, M Dorigo, A Reina - 2024 IEEE/RSJ International …, 2024 - ieeexplore.ieee.org
Making fast and accurate consensus decisions through local communication and
decentralised control in a swarm of simple robots can be a very challenging endeavour. In …

The neglected pieces of designing collective decision-making processes

Y Khaluf, P Simoens, H Hamann - Frontiers in Robotics and AI, 2019 - frontiersin.org
Autonomous decision-making is a fundamental requirement for the intelligent behavior of
individual agents and systems. For artificial systems, one of the key design prerequisites is …

Scalability in computing and robotics

H Hamann, A Reina - IEEE Transactions on Computers, 2021 - ieeexplore.ieee.org
Efficient engineered systems require scalability. A scalable system has increasing
performance with increasing system size. In an ideal situation, the increase in performance …

Voluntary retreat for decentralized interference reduction in robot swarms

S Mayya, P Pierpaoli… - … international conference on …, 2019 - ieeexplore.ieee.org
