Nanos

The Nanos are not small robots, but tiny building bricks that are connected to a computer and that can combine and connect with each other to form a wide variety of small machines with an expanding "brain" the more of them are connected.

They are thus flexible, able to larn new configurations and addapt to new needs.

The Traitors will modify their programming so that they are now ubiquitous all across all the ships.
