Since I’m finished with my Gravity Gun replica I’m starting a new project because it feels it would be the right time to try out some new things I learned in the near past. And by that I mean motorizing stuff by using stepper motors, servos, drivers and all of the controlling which comes with it.
That gave me the inspiration to start on this very project, a completely animatronic version of Wheatley, the humorous robotic sphere you definitely know if you ever got to play one part of the Portal series by Valve.
Back when I worked on the Gravity Gun I already started drawing all kinds of sketches to give me an idea how I could tackle the project at best. Wheatley isn’t a quite difficult character to construct when it comes to his overall shape but the challenge definitely lies in working out his internal mechanics
:)
I have studied Wheatley’s behavior quite a bit and came to the conclusion that a few of his moves are impossible to recreate while keeping the inside clean and not having it stuffed with mechanical parts, gimbals, gears and motors.
Luckily some awesome guys over at The Replica Prop Forum were such a great help on the overall project by providing me with detailed views of Wheatley’s model from the game which ended up in being the best blueprints I could ask for
:) @Fishbowl, if you ever happen to read this: thanks a lot!
:)
After weeks of thinking, trying and fooling around I came up with a mechanism which will hopefully fit perfectly inside Wheatley without compromising in variety of his movements too much.
It’s not yet done to 100% but I’m so hyped for this project so I couldn’t wait any longer to get it started. I’m sure a few things will change while working on it but basically the main stuff is done already.
What will be possible function-wise is as follows:
• Moving the eye-corpus 25° in every angle possible from its original position.
• Moving the eye-pupil 15° in every angle possible from its original position.
• Moving eye-lids independently from fully open to nearly fully closed.
• Rotating the “bucket” in Wheatleys backside around 40° to the left and right.
• Moving Wheatleys front bars on the top and bottom independently to get even more expression.
• Having a proper sound module embedded to bring Wheatley to life and add personality.
• Controlling Wheatley via a self-build remote & app.
• Voice regonition.
• Using Wheatleys “flashlight”-function as seen in-game.
As Wheatley is quite complicated to build by hand and 3D printing is a thing now I decided to have most of its parts printed! For that I bought myself a small 3D printer, the Wanhao Duplicator i3.
Starting with the outer shells I will update the progress tomorrow showing you exactly that
:)
Hope you guys are excited to this project come alive.
If there are any questions, throw them at me!

Cheers and thanks for reading/checking out. Stay tuned for tomorrow!
