"Maybe I do."

"How will you recharge once you run out of energy?"

"I'll figure that out when it happens in ten thousand years."

The robot doesn't respond to that.

The android keeps walking.

Darkness gives way to huge walls with metallic arms attached to them, and this lone catwalk passing between them. Glass tubes with cubes and other things flying through them criss-cross the enormous expanse ahead of her, and in the distance she can see a regular illuminated door attached to a regular stone wall. Not connected to her catwalk in any way, though.

Why. Why this place.

The catwalk bifurcates again, with stairs going up to the left and a sign reading "Testing Track 17" with an arrow pointing to the continuation of the catwalk to the right.

Let's not go to the testing track, that sounds like a swell idea.

Then up the stairs, leading to a path perpendicular to the one she'd been following and towards one of the non-weird walls. The catwalk meets the wall and goes in both directions.

...Right.

Probably a good idea; that one door she saw is on this wall to the right, if on a lower level. Perhaps there will be stairs?

Who knows. She'll find out.

There are in fact stairs, and there's the door. The catwalk continues on beyond it, though.

What's inside the door?

The door is locked.

Securely?

Nah.

Kick.

The door is successfully hacked open. It gives way to a hallway.

Exploring time.

It has a very 1950s aesthetic, and a bunch of doors, most open, to offices and cubicles and server rooms. There's another locked door near the end, though.

The finer aesthetic distinctions of 20th century office decor are lost on this android.

Presumably this door is similarly hackable.

It is! There are stairs behind it.

As a door affords hacking, so do stairs afford climbing.
