Article Synopsis
  • Aggressive behavior among male crickets establishes a dominance hierarchy, where defeated males take time to avoid their winners but may lose their aggressiveness if they engage in repeated fights.
  • The degree of aggressiveness is influenced by group size, limiting how many crickets can fight at once and thereby affecting overall group dynamics.
  • A robot model was developed to study this behavior, using experiments and simulations to show that local interactions among robots could mimic the group-size-dependent strategies observed in crickets, relying on oscillators and memory of fight outcomes.

Insects have small brains, but their behavior is highly adaptive; this leads us to conclude that their brains possess a simple adaptation mechanism. This paper focuses on the pheromone processing of crickets, varying their aggression depending on their global neural connection, and proposes a behavior selection mechanism that can be controlled by network transformation. The controller is composed of an oscillator network, and its behavior is decided by the synchrony of organic oscillations.
