Giu's Robot Repairs - Part 4

by Raffa

Hey everyone!

Time for the final part of my series that gave a little look behind the scenes of the creation of "Giu's Robot Repairs".
If you missed the first three parts, check them out here:

Let's start with the painting of the base!
The base was basecoated roughly with a black spraycan. The finer details and undercuts were then basecoated black with the airbrush. I started spraying on some basic colors while I already payed attention not to overspray too much on other parts.
I applied some base colors and started weathering the door. At this stage it looks very annoying (like a comic book...) to my eyes. I have to quickly move forward, the plan was to paint the base in 1 day as I didn't have more time for it.

At this stage some more shadows were airbrushed and I started painting details on the brickwall.

You can see some of the painted lights and shadows on the bricks here. I also tried to give the bricks some color variation.

I used grey pigments mixed with water to create the plaster. Just paint the mix in the recess and use a cotton dab to remove the rest that didn't get in the recess.

Using oil based colors I created some color variation in the corner using a dark green. To vary the colors as much as possible and make the base as interesting as possible I regulary used my brush to splatter different colors at different places. Using white spirit I could easily move the color around.

Using Mig Productions "Oil and Grease Stain Mixture" and a brush casing I did some oil stains on the floor. I did this multiple times through the painting process to simulate multiple oil stains that got covered with dust over time and oil stains that are newer.
Another test fit of the already painted details, looks good so far! You can see the concrete floor changed quite a bit, this was due to airbrushing a mix of pigments and airbrush thinner.

While testfitting, I sprayed some marks for all the objects that will be placed later. I used those marks to spray strong shadows for the objects that will be glued later.

Some "newer" oil stains that I applied after using pigments to make the floor look more dusted.
I started weathering the upper roof. I carefully applied the rust streaks in a realistic way. Thinking about the form of the roof and how the rain washed down the rust from the damaged spots and the nuts makes it much more believable.

More rust on the door and some details!

Rust rocks!

This testfit really starts looking serious :) It's an indescribable feeling of seeing such a big project growing and when more and more elements get into place it makes my heart explode from joy. Oh what a fool I was, because there was still a LOT electrical work to do :(

Some small paintworks still had to be done like the backside of the shop sign.

Now the real troublemaking part of the project started... Finishing the control plate was the next step. This shows the first layer connecting all the switches and buttons I installed.

Here is the second layer built up, you can see the ribbon cable I will be using to connect the control plate to the rest of the project.

Building the fixed voltage regulators for 3,6V and 3V. I needed three different voltages, 9V for the music amp, 3,6V for the shop sign and the MP3 player and 3V for all the camera, lights and the motor.

The almost finished control plate, you can see the MP3 player and the music amplifier fixed on the second layer of it. After this photo I found much more stuff to connect, in the end there were 34 connections to the ribbon cable.

No words can describe the madness I encountered when soldering all of this together.

The robot and it's self build custom fish eye lens. It was build from the lenses that I scavenged from different cameras.

Slowly things get into place and work, wow what a feeling :D

I still had to do the "fake" cables connecting everything. This was pretty important to me as the viewer should get a feeling that the setup on the table somehow makes sense :)

This is a special maintenance opening in the back of the socket that I used to wire everything up.
That was the first time I was seriously worried about my flight to Italy... what will the security guys think of this contraption???

My worktable after putting everything back to it's place that wasn't trash... This is all the leftovers from some days of electronic hardcore work.... and that's the point the project was finally finished and packed for Monte San Savino. I yelled and danced in the studio. The feeling of finishing such a big and exhausting project is beyond price.

And finally I will show you a video and some photos of the finished project ... in the next post in some hours :)

To shorten the wait, you will get some more photos from the project!

I hope you enjoyed this final part of the behind the scenes articles of my project, stay tuned for the final photos and a video!

Best wishes,
