Mathematical Modeling and Analysis of Multirobot Cooperative Hunting Behaviors

الملخص EN

This paper presents a mathematical model of multirobot cooperative hunting behavior.

Multiple robots try to search for and surround a prey.

When a robot detects a prey it forms a following team.

When another “searching” robot detects the same prey, the robots form a new following team.

Until four robots have detected the same prey, the prey disappears from the simulation and the robots return to searching for other prey.

If a following team fails to be joined by another robot within a certain time limit the team is disbanded and the robots return to searching state.

The mathematical model is formulated by a set of rate equations.

The evolution of robot collective hunting behaviors represents the transition between different states of robots.

The complex collective hunting behavior emerges through local interaction.

The paper presents numerical solutions to normalized versions of the model equations and provides both a steady state and a collaboration ratio analysis.

The value of the delay time is shown through mathematical modeling to be a strong factor in the performance of the system as well as the relative numbers of the searching robots and the prey.
