Numerous studies have recorded and modeled the optomotor feedback response of individual insects in corridor-like environments over the last few decades. The question of whether these responses contribute to or inhibit group flight/swarming behaviors has not been equally explored. To consider the problem of how biological agents incorporate visual feedback in multi-agent environments, this study extends a wide-field integration model of insect optic flow sensing and visual feedback in a corridor-like environment to feedback in multi-agent dynamic systems. Theoretical analysis and a robotic experiment are conducted for an individual agent operating in an established group formation of other agents. The results indicate feedback from wide-field integration of optic flow input can help participate in established swarms and demonstrate the importance of relative motion between agents in maintaining the swarm.
