Abstract:
The availability of relatively capable and inexpensive hardware components has made it feasible to consider
large-scale systems of autonomous aquatic drones for maritime tasks. In this paper, we present the CORATAM
and HANCAD projects, which focus on the fundamental challenges related to communication and control in
swarms of aquatic drones. We argue for: (i) the adoption of a heterogeneous approach to communication in
which a small subset of the drones have long-range communication capabilities while the majority carry only
short-range communication hardware, and (ii) the use of decentralized control to facilitate inherent robustness
and scalability. A heterogeneous communication system and decentralized control allow for the average
drone to be kept relatively simple and therefore inexpensive. To assess the proposed methodology, we are currently
building 25 prototype drones from off-the-shelf components. We present the current hardware designs
and discuss the results of simulation-
based experiments involving swarms of up to 1,000 aquatic drones that
successfully patrolled a 20 km-long strip for 24 hours.
