Information Transmission Strategies for Self‐Organized Robotic Aggregation

Key Points

Self-organized robotic aggregation relies on effective information transmission strategies to coordinate behaviors and achieve group cohesion.
Collective robots use local interactions to gather information, leading to successful aggregation behaviors observed in many robotic systems.
The review categorizes previous studies by the type of information transmitted, emphasizing the role of communication in self-organization.
Current challenges in the field are discussed, with suggestions for future research directions to enhance robotic aggregation methods.

Abstract

In this review, we discuss how information transmission influences the self‐organized aggregation behavior of swarm robots. As a fundamental behavior observed in many collective systems, aggregation has been widely studied with collective robots equipped with programmable motion and local interaction capabilities. These robots gather group‐level information through communication or physical interactions, adjusting their movements accordingly, and ultimately achieve aggregation. In this review, we focus specifically on local interactions regarding information transfer. Previous studies are categorized based on the usage of the transmitted information. We summarize the information transmission strategies employed by collective robots to facilitate aggregation. Additionally, we highlight the current challenges in the field, discuss potential directions for future research, and outline several possible applications.
