AI Overview
Seeking an acoustic communication system for drone swarms that uses propeller noise to share position data. This technology will enable decentralized swarming by allowing drones to autonomously maintain formation through sound-based communication.
This summary is AI-generated from the official solicitation.
Key Details
Official Description
This topic seeks innovative research and development efforts towards an acoustic-based communications system that enables sUAS within a swarm to communicate and exchange information about their relative positions. This capability will support intra-swarm communications by using sound primarily generated by the sUAS’s propellors as a carrier wave to encode data between drones. The system should spatially decompose incoherent sound waves produced by the sUAS’s propellors during normal operation in...
