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.

Hey,,,, Where have you been? Welcome back. Thanks for the compliment. I printed out a case for the ultrasonic sensor which I will mount on the leg. I am still looking for a caster that I like. Ron
I'm not sure if anyone can help me with this, I am having a really hard time with finding a correct gear for the dome to rotate for the Jakks R2-D2. Please help!
@hockeynorton When I tried something similar to this, I attached a rather large wheel onto the end of a servo, and fit it snug in the base. I am not familiar with the Jakks R2-D2 but it should work. Just hook up the servo like any other and program it to your liking.
Hello @Hockeynorton,
I will try to look up the gear file. I may still have it.
I really think you may want to go to a servo as I showed in this thread. I tried the gear and the motion was very slow. The servo gives a nice realistic movement. If you wanted a 360 degree movement you could modify the servo and add an external pot for positioning.
Give me a little time to find that file. I hope I still have it.
Regards, Ron
You got lucky ! I found it on the first try..

Awesome! Now I never dealt with 3D Printers before, I'm new to this world and just started programming in my free time a few months ago. I'll check out the STL file when I get home from work. I'm very open to learning and figuring things out on my own, but this gear has me going nuts. I just want to be able to actuate some rotation and motion. As of right now my R2 has a lit power button on rear, the arduino uno, a sound module, and Leds. My goal was to start simple. The program is a simple loop where every 30 seconds a different sound plays and a few LEDs light up. I'm very pleased with it as is, but I just want more and more.
Sounds like you are having a good time. I think you are hooked on this stuff.
The .stl file is the file a 3D printer uses to make the part. There are some libraries and other places which have them available, and allow you to print stuff on them, for a fee, or you can have it made by someone who has a printer.
Seeing you are using an arduino, I suggest you get a servo and try your hand at making it work. I also posted the .stl file for the Dome arm here. You could use the arm to move the dome easier than trying to use the gear. Just a suggestion. Servos are cheap on ebay, but you can get them here, at a Hobby Shop or Radio Shack.
Someday look at the stuff in the ARC. You will find programming with an EZB gives you all kinds of thing to play with, camera, all kinds of sensors, servos, tracking, motion, speech recognition.
Your R2 could do a lot ! The neat thing it this stuff is easy to program.
The main thing is to have fun and enjoy.
Regards Ron
Any video of R2 yet?
