Radoci

Radoci is a fictional class of autonomous underwater drones depicted in speculative fiction and hypothetical maritime research scenarios. In these contexts, radoci are described as compact, modular robot platforms designed for deep-sea exploration, monitoring, and data collection, capable of long-endurance missions beyond the reach of human operators.

Design and capabilities: Radoci are typically described as 0.2–0.5 meters in size, with spherical or egg-shaped hulls and a compact propulsion array. They carry hydrophones, low-light cameras, basic chemical and temperature sensors, and a modular sample-collection tool. Power comes from rechargeable batteries, sometimes supplemented by energy harvesting. Communication uses acoustic modems for long-range data, with tethered variants offering higher bandwidth. Some models feature swarming capabilities for cooperative mapping and obstacle avoidance.

Deployment and use: In fiction, radoci are employed for seafloor mapping, environmental monitoring, wreck exploration, and search-and-rescue operations. Their modular design allows interchangeable sensor pods and tools. They may operate autonomously or under supervision from a surface vehicle or facility. Mission duration is typically constrained by energy budgets and data throughput, with some depictions allowing weeks of operation.

Etymology and reception: The term radoci appears as a neologism in multiple works, with no single canonical origin. It is sometimes framed as a blend of radio communication and cognition or observation, though authors diverge on the root concepts. The concept is used to discuss the future of underwater robotics and to illustrate challenges of deep-sea autonomy.
