Collective Cognition on Global Density in Dynamic Swarm

Area of Science:

• Robotics
• Artificial Intelligence
• Collective Behavior

Background:

• Swarm density is crucial for robot swarm performance, impacting communication and collision avoidance.
• Real-time measurement of swarm density is challenging due to unobservable workspaces or dynamic swarm sizes.
• Suboptimal swarm density leads to ineffective cooperation or task interference.

Purpose of the Study:

• To propose a distributed algorithm for collective cognition of average global swarm density.
• To enable robot swarms to make decisions about their current density relative to a desired density.
• To allow for swarm size adjustments to achieve target density.

Main Methods:

• A distributed algorithm for collective decision-making on swarm density.
• Real-time estimation of average global density within the swarm.
• Integration of swarm size adjustment mechanisms.

Main Results:

• The proposed algorithm enables swarms to determine if their density is too high, too low, or optimal.
• The method is robust to changes in swarm size and workspace observability.
• Facilitates adaptive swarm behavior for improved operational efficiency.

Conclusions:

• The distributed algorithm effectively addresses challenges in measuring and controlling robot swarm density.
• Enables swarms to self-regulate density for enhanced cooperation and task focus.
• Provides a foundation for more adaptive and efficient robot swarm systems.
