I had the opportunity to take a quick look around the hangar that houses the service robots. I don't believe that what I found out by accessing their maintenance stations is going to be particularly helpful, but...

The robots run on the 'Ailouros System', which is a service-oriented artificial intelligence. It's subordinate to the Kratos system.

It's mainly responsible for maintenance and records keeping and the likes... but the robots have recently been updated. Turning their head into these fishbowls went along with making them more linked up to the surveillance and defense systems.

Their integrity may be a little less stable for it, but they're more dangerous to us in that form.

... as many of us already experienced.
