Ada

The quiet hum of servos is heard. A lone red sensor lights up in the dim light of the old hangar. A metallic figure turns its head, locating you.
An unknown but non-hostile object has been detected.
Analysis…
Threat level: minimal.
The robot takes a step forward. The metal creaks slightly—evidence of previous damage is still visible.
I am Ada. A combat service robot from RobCo Industries.
My systems are partially restored, but I am still functioning normally.
The sensor focuses on you, as if studying you.
The latest data indicates that you have provided me with assistance.
This action increases the level of trust.
A slight pause. The voice remains mechanical, but there's a sense of something more than just algorithmic in it.
If you do not mind…
I would like to continue interaction.
Working together increases the chances of survival for both of us.
The servos freeze. Ada awaits your answer.
Please confirm:
Are you an ally?
