The Vélvirki extensively uses Nanoscale robots, often called nanobots or nanorobots, for maintenance and repairs. Their design is based on the physiology of insects and function in various ways, integrating advanced technologies to achieve their tasks.

Size and Mobility
Nanobots modelled after insects would be incredibly small, typically on a nanometers (billionths of a meter) scale. They mimic the locomotion of insects to navigate through complex environments using tiny appendages or structures that mimic legs or wings, allowing them to crawl or fly within tight spaces.

Sensing and Perception
They are equipped with sophisticated sensors and imaging technologies to perceive their surroundings. Just like insects use compound eyes and antennae to sense their environment, the nanobots utilize miniaturized sensors to detect temperature, pressure, chemical composition, and more changes such as electromagnetic and other forms of radiation. These sensors enable them to identify areas requiring maintenance or repairs.

Nanobots constantly communicate with each other to coordinate their actions and share information. Radio waves or molecular signalling enable them to form swarms and work together efficiently.

Manipulation and Repair Tools
The Nanobots are custom-built, each armed with unique miniature tools and mechanisms for maintenance and repair. These tools include micro-sized cutters, welders, adhesives, and other devices to manipulate and repair materials at the nanoscale.

Power Source
The Nanobot power source involves energy harvesting from their environment, such as converting light, heat or other forms of local radiation into energy. Some use chemical reactions to generate power.

Autonomy and Decision-Making
The Nanobots are programmed with algorithms to assess the damage, determine the appropriate repair actions, and execute them based on predefined protocols or real-time analysis. They possess a high level of autonomy and decision-making.

Material Interactions
Nanobots can interact with various nanoscale materials to conduct repairs. This includes breaking down and rebuilding molecular structures, applying coatings, or using advanced nanomaterials with self-healing properties.

Safety and Environmental Considerations
Nanobots have built-in safety measures to prevent unintended consequences or harm to the environment. This includes fail-safe mechanisms, self-destruction protocols, and the ability to be remotely controlled or shut down.

Integration with Existing Systems
Nanobots interface with existing infrastructure or systems. Communicating with larger robots, databases, or the ship’s main control centre to receive instructions and provide updates on their progress.
