Today, I'm going to teach you how to build a working, life-sized, phone-controlled Starwars BB-8 droid! In this tutorial, we are only going to use household materials and a little Arduino circuitry.

`

My Christmas Gift For Dad: One of my dad's hobby is being a toy collector (Hot Toys, Enterbay & Etc..). He grew up watching movies from the 80's, including Starwars! He is a really huge Starwars fan. When the Sphero BB8 was announced, he wanted it so badly! The Sphero toy cost $150 online, $210 in our country (Philippines), not to mention that they ran out of stock easily! It's not the typical toy that you would buy impulsively. Knowing with my past experience in building robots, I figured I could build a life-sized version of the Sphero BB8 for less than $100. I also saw this as an opportunity to spend some father-and-son time with him. This is what we ended up building in the week of Christmas! Anyway, my mom and I also got him a Sphero BB8 and used it as our reference for building this project. For him I guess, the best gift was the time we spent building it together.

Why Household Materials?

Due to the limitation of materials, I resorted in using the materials around me. (deodorant roll-ons as ball bearings, canvas as fiberglass, Christmas balls as the eye & etc.. ). A lot of people could relate to this. My approach on building the project doesn't require 3D printers, CNCs or Milling Machines!

<p>BB 8 CIRCUIT TO ARDUINO,</p>
<p>Hi everyone. I'm 17 and I'm trying to build this, but I have a problem. I bought the two metal gearmotors, but I don't have the wires to connect them to the Motor Driver Shield. Where can I find them? What material should they be made of? Thanks</p>
<p>I made it. Here are the images: It cost me over 1000 USD and I'm 13.</p>
<p>I am making one too. I am 12 years old.</p>
<p>Good luck</p>
<p>Thanks!</p>
<p>Ineed some help with the programming.even i am 13.i am not using the pololu vnh5019.I am using adafruit motor driver shield v2.3 . pls help me</p>
<p>Here is the inside, the templates and the finished ball.</p>
<p>What made it cost so much?</p>
<p><a href="https://docs.google.com/spreadsheets/d/1X1660RH9u0zMqX6ZIQGvnTYxJhE51bQaxhcSPcqM8zY/edit?usp=sharing" rel="nofollow">Here is the expense sheet.</a></p>
<p>Thanks for the breakdown - I find the China sites great for supplies like these at a fraction of the cost of the more usual shops, (at the expense of 3 to 4 week postage times) - this is a good site and would have most of the electrical, painting and magnet items on your expense sheet.</p><p><a href="http://www.banggood.com/">http://www.banggood.com/</a> </p><p>There are even cheaper sites (like aliexpress) - but I prefer the above as its just the one seller you are dealing with.</p>
<p>banggood is a good alternative to amazon and pololu.</p>
<p>i'm frm INDIA......I'm an able find Motor Shield and Metal Gearbox-.......can i get other way to build it???</p>
<p>Arnavk do you have the pdf file for BB-8s artwork?</p>
<p>I free handed it. </p>
<p>Yes. Adafruit is a great alternative. You can also use Arduino's Motor shields and compatible motors.</p>
<p>thanks for your advice :).</p>
<p>No Problem</p>
<p>are any of these motor shields compatible with raspberry pi</p>
<p>A raspberry pi is a computer. I would suggest digging into that. Good Luck :)</p>
<p>can u tell me one i shod install FIRST. ???</p>
<p>thanks........i'm confused code i shod install....????</p><p>1)BB8 Aruino code. (OR)</p><p>2)Pololu Libray (Dual motor Shield)</p>
<p>can you send me measurement for dat wood work.<br>saikiran.sai03@gmail.com<br></p>
<p>The measurements are in the image:</p>
Can you please send me the PDF...thanks <br>
<p>I didn't make pdf's but in my pictures I showed my templates.</p>
Thanks so much! I'm in the same situation as you. I wish this guy would fix the instructions so they made some more sense.
<p>I know. It was very challenging.. Good luck to anyone building this, and may the force be with you ;)</p>
What did you do for wheels. I can't seem to find any online.
Tamiya 70111 Large Diameter Wheel Set
<p>Hi,</p><p>I resorted to the Pololu wheels after buying the hubs that were compatible with the motors. I bought them off amazon, but you can buy them on Pololu's website.</p>
Hey, thanks for all of your help. Is it possible that I could have a link to where you found these wheels. I am having very little luck.
<p>Hey i have a problem with the paper mache canvas part, it keeps wrinkling up during the drying process, thoughts? why is this happening? also where is the drawing pdf file?</p>
<p>I have the pro, or premier of instructables, and I still cannot see where to get the drawings as mentioned in Step 14.</p>
The head seems to be to big for the body even though I looked up the dimensions, thoughts?
<p>I made it, I use a raspberry PI for the controller and use ultrasonic sensor ,so it move it self without remot control , but I have any problem like , it can't detect the lower obstacle, can you help me ,please ?</p>
Blueprints
I don't see the bluprints
<p>The head seems to be to big for the body even though I looked up the dimensions thoughts?</p>
can i use my raspberry pi in this project
<p>Nice</p>
<p>how do you get the beach ball out of the body? when he cut the body in half the beach ball wasn't inside.</p>
<p>It pops when you cut it. He must have removed it in the video at some point.</p>
<p>Excuse me but on step 14, I can not seem to locate the file package is it there for everyone else?</p>
<p>yes but you have to upgrade to premium</p>
<p>Did anyone else have trouble getting the beach ball round? I blew it up as full as it would go, applied the paper mache, and the surface is not uniformly round. Looks as if parts contracted slightly. It's close, but certainly not a perfect sphere. Thoughts?</p>
<p>the same thing happened with me,try using a styrofoam ball and using it as a mold</p>
<p>wow</p>
<p>Hi! How can I fix the two parts of the body?</p>
