Low-Power Low-Cost Acoustic Underwater Modem

Alexander Gabrecht, Benjamin Meyer, Christoph Osterloh, Erik Maehle, Christian Renner


Recent advances in electronics and robotics enable automated and potentially unsupervised environmental underwater inshore monitoring with swarms of small, low-power, autonomous underwater vehicles (AUV). To enable flexible and self-organizing operation, underwater communication is required. However, existing solutions aim at long-distance communication, leading to high unit cost, high power consumption, and large dimensions; hence rendering their application in robot swarms practically and economically infeasible. In this paper, we present our ongoing development of a low-power low-cost underwater modem for acoustic communication. It features a low unit cost, small form factor, and low power consumption. It is flexible, robust, and achieves a suitably high data rate and low transmission delay for swarm coordination tasks.
