Hello to All,
Here is the Walmart R2D2 project.
I disassembled the unit and was surprised to find it was more than a shell. There are opportunities to use the inserts in the dome to mount LEDs and a camera, and a bearing ring which has a ring gear to allow the easy installation of a servo or gearbox to move it. I found, using a flashlight, lights can be mounted against the skin to light up the panels.
The body has some areas which can be modified or changed out for more flaps or lights. Due to flat areas on the bottom of the body, mounting an additional front foot should be somewhat easy.
The legs have a flat bottom and a pod to mount either a motor or continuous servos for the drive.
I will soon begin the build by 3D printing a front foot and mount to see how the project will come together.
There is a 6" Ruler in the front of the pictures for reference.

Hi @outcastrc,
Thanks for the information. I appreciate the conversion and will plan on using it in my next upgrade. Except for a couple of wiring changes I want to do, my R2D2 is running. I plan on putting up a video of the basics I have so far. He is limited on function right now, but I plan on more scripts for him. Due to the Holidays I had to stop for a while but I will soon start working on it.
Post some pictures of yours. I didn't know Costco had an electronic version and would like to see what you have done.

The Costco electronics are pretty simple. Coin slot push button, sounds, flashing lights in his dome, and it spins the head back and forth. His one leg hops up and down as well. I'll most likely use the limit switches, the head motor system, and speaker but everything else is getting turfed.
In between shoulder prototypes I have been printing 40% scale stls from astronmech.net to enhance the droid where Jakks Pacific fell down in the design.
I have in this thread, an .stl file of the foot and front leg which is pretty detailed like the original. The scale is pretty good. Take a look.
Unless the motor/ gearbox is pretty fast, you may want to look at a servo direct drive to the dome. I found it more realistic than a gearbox/motor and what is nice you can stop in position. No need for the limit switches.
Have Fun with your mini R2 !
Thanks for the pictures of the Costco one. My original ideas were correct.

Hi Andy, Did you ever make a video of your Walmart R2D2? When you get the chance, email me. Email listed on my user/settings page. Thx.
Hi @rgordon,
I have been waiting for the compass issue to be resolved so I could work on the navigation portion of R2 before I posted a video. He does run well in voice command mode (forward, stop reverse, left and right ) camera tracking works but not fully tuned, and dome lighting and rotation works well.
I really want to get the compass installed and maybe some pings so he will be able to roam and navigate to different areas by command. I put him on the bottom of my project list until the compass issue gets resolved.
He has come out as planned overall and will be a good companion.

I couldn't find your email.
My bad. Thought you could see it by clicking on my user name. Want to talk to you about the .stl files.

Hi Rex, Message sent. I will be watching for your reply.

@Ron.
I hope you get back to the little fella soon. Does the recent compass fix help you with what you want to do?
Just a thought, but what about putting a ping in the front of the centre foot? Might work well and not loot too out of place.
