I can actually make an AI out of that, if it was bigger

I think going for prosthetic eyes would be perfectly creepy. I hope you follow through with this idea. Might be a good push to make some spooky tech in time for Halloween eh?

A very interesting build. I'm not familiar with Portal or even GLaDOS but there are lots of other robot heads that could be created in this manner. I have wanted to make some sort of robot head recently as I have seen so many after watching many Sci-Fi shorts on YouTube. The eye movements and control are some of the best bits as they can be really freaky to watch. As humans I think we are inherently drawn to focus on the eyes of other people/animals/robots and tend to pay less attention to the rest of the robot/figure. Get the eyes right and you achieve most of the effect.

I worked with the Robothespian robots ( https://www.engineeredarts.co.uk/robothespian ) for a couple of years and when powered on but not actually doing anything their eyes (and head) would follow you around the room - it could be very disconcerting. I have thought of reproducing something similar for some time, probably with just the eyes moving about. Maybe with some real prosthetic eyes!

Hey Frank. You can find the Fusion360 file in the attached zip file above.

Can you also share the stl's? doing something similar but focusing on the head movement... but your details are so well done...I can reuse some..

Thanks DAB! I agree. Definitely gonna be putting her to future spooky use.

Nice build.

It would make a good Halloween prop.
