Spider bots have too much free time as it is. I've seen them lounging around in the library, thinking they are hidden.
They can't hide the metallic sounds of their movements, so I know they are in there. Probably checking out the cheese and wine.
That's fine, but if they start in on mixing up the frozen margaritas, we may need to quarantine that level until the revelry settles down...
The spiderbots have two modes of operation. A somewhat autonomous mode allows them to attend to tediously boring and repetitive maintenance chores.
But they can also be teleoperated. There is a good possibility some children have been trying to surreptitiously sneak into some restricted supplies.
Just check out who was signed on as operator, (and never give out your password!)
