Author:djsures    http://www.dj-sures.comI'm this guy who builds robots. Check out my website to see what else I'm up too. :)

Intro:  Build an autonomous Wall-E RobotHi! After a kabillion requests, here you go! This robot is running the EZ-B available at http://www.ez-robot.com

First a little introduction: Watch Video

I started off with the toy titled "Interactive Wall-E". Available at toys'r'us current price $34.99

I am a robot hobbiest and have a lot of expierence with the programming and design to give robots expression and life. The first bit advice I can lend is to be confident.Second advice is to be creative. Together, you're mind will figure out the rest for you :)

There are plenty of peices available to you. My workshop is nothing special. I keep a supply of parts that are low cost. I usually collect items from disassembling othertoys :) . Sadly, servos are the most expensive parts of the bunch.

For fasteners I use Zip Ties and an arragement of small screws, bolts and nuts. All are available in cheap combo kits at your local hardware store.

To modify the casings, i use a speed adjustable dremel and sometimes my soldering iron to melt plastic. For dremeling, please keep a vacumn nearby. *Warning: Formelting, keep a window open with a fan!!

Also, if you choose to melt plastic peices, use a seperate bit on your soldering iron. The plastic will burn to the tip and make soldering a pain in the butt!

Now for the programming part... This is actually very easy. I do my programming for my robots using the EZ-Robot Project and the EZ-B Robot Controller.  It does notrequire any programming. You can just plug in your servo motors and control the robot from your PC. It also contains voice recognition and a bunch of other neatfeatures. You can get it here: http://www.ez-robot.com

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 1: PartsOkay hopefully you've created a nice work area. Someplace with a table/bench that you don't mind getting dirty/burning/scratching/etc. (ie don't use your dining roomtable!)

Here is a list of the parts I used...

- 1 EZ-B with SDK or EZ-Builder softwareAvailable at http://www.ez-robot.com 

- 2 Parallex modified servos for the drivetrainAvailable at: http://www.hvwtech.com/products_view.asp?ProductID=114

- 1 GWS Standard servo for the head (Left and Right motion)Available at: http://www.hvwtech.com/products_view.asp?ProductID=878

- 2 GWS Pico servos for the arms (Up and Down motion)Available at: http://www.hvwtech.com/products_view.asp?ProductID=863

- 1 GWS Micro servo for the head tiltAvailable at: http://www.hvwtech.com/products_view.asp?ProductID=862

- 2 Sharp Analog Distance SensorsAvailable at: http://www.hvwtech.com/products_view.asp?ProductID=88

- A collection of 3-Conductor Servo CablesAvailable at: http://www.hvwtech.com/products_view.asp?ProductID=690

- 1 Box of assorted small screws/bolts/nutsAvailable at your local hardware store

- 1 Hobby Hot Glue gunAvailable at Walmart or hobby store

- 1 bottle of krazy glueOr any type of good strong plastic glue

- 1 Soldering IronI use an adjustable temp range soldering iron, which is costly but recommended. Sometimes you can come across these used in bargain classifieds or at electronicsupply surplus shops.

- 1 Case of Jeweler Screw DriversAvaiable at walmart or any hardware shop

Step 2: Take the toy apartUsing your screw driver set, you'll want to disassemble the entire toy. Keep track of how it came apart, because the goal is to re-assemble :) ..

*Note: It is not neccessary to take apart the Eye Encloser. The wires from the Eye Encloser can be connected to your micro.

Step 3: ArmsYou'll need to mount the servos onto the top part of the toy's case. This is going to be your first modification to the body. Hold the two mid sized servos to where theoriginal arm mechanism was and notice how to fit them.

The photo on this step shows a mounted servo, and the original mechanism. You'll of course want to have both servos mounted, one for each arm.

Use the dremel to cut away the plastic on the ends to fit the servos. Make sure you use a low speed on the dremel. Drill Style cutting bits work best.

- I used the glue gun to create a nice tight fit for the servos.

- I then melted two tiny holes in the plastic to fit small screws for additional support.

Mounting the arms to the servos is a little tricky. I don't have a clear photo of how i did it, but be creative. The servo packs come with a variety of bits and extensions. Becreative with those extensions. I took a 4 arm extension and trimmed it down to fit within the arm. No glue or screws were neccessary.

Also, once you figured out how to mount the arm to the servo, make sure the servo and arm are both in the centered position. Becuase remember, the servo doesn't spin360 degrees. It has a Start and Stop position! So for full movement, you're not going to want the arm mounted at bottom of the servo's positioning, or it will only be able togo up from that point :)

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 4: Mounting the head/neckThe neck will mount to the GWS Standard servo. This will allow it to move left and right.

*Note: Like the arms, the servo needs to be centered ;)

I used a combination of the dremel and soldering iron to flatten the neck adapter. I then melted 3 small holes to fit screws onto the circular servo accessory.

To fit the servo and mounted head bracket, you'll need to dremel the hole larger. Also remove and break off any plastic peices that prevent the servo from sitting flushagaint the plastic.

Recycling some of the wall-e screws and mounting locations, you'll be able to mount the servo.

When I mounted the head to the neck bracket, I used a zip tie temporarily. I later replaced it with a bolt and nut.

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 5: Drivetrain - part 1Now let's give wall-e some wheels!

So the toy doesn't have any motors or drivetrain. It's a push toy. So you'll need to be very confident and creative here.

Twist and turn the wheels until the metal axel breaks loose. It's quite a struggle! I ended up using a dremel and cutting most of the pastic away that attached the axel tothe wheels. You're going to want the inside of the wheels flat anyway, so don't worry :)

Now we're going to simply pry out the center cap on the wheels. This will expose a philips head screw. Remove that screw and the wheels will come apart.

Using the 4 arm accessory of the Parallex Modified servos, melt corresponding holes into the inside of the wheels. Use small screws and attach the 4 arm accessory towheel.

Trim off any part of the servo accessory that sticks out using the dremel.

Do both sides the same.. Look at the pics :)

Step 6: Drivetrain - Part 2Okay now we're going to mount the drivetrain to the case. This is exciting becuase it's a lot of dremeling!

Take a good look at the pictures and see how much to cut away.

It's best to take this part slow. I use a marker to outline where to cut. ... I cut a little, then measure, cut a little, then measure. Etc...

Once the servos fit flush and the mounting bracket fits to the case, then you must be close! Sweet!

To mount the servos, i first used a bead of hot glue gun to hold the servo in place. Glue guns are great because they'll provide a temporary mount, but not permenant byany means!

To securely mount the servos, i used zip ties! I used the nice fat zip tie, and a pair of plyers to tighten it up solid.

Yay next step!

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 7: Distance Sensor & AssemblyI supposed you'll want your wall-e to see. So did i!

So I used one of the sharp distance sensors mounted on his neck. I had to dremel a bit of the sensor housing to make it fit flush.

Maybe melt/drill a little hole through the top plastic of the box to push the wires through.

The wires that come with the sharp sensor are very small and easily break from fatigue. I replaced the wires with the Servo wire/plug combo that is listed in the parts.

I use those servo wire/plug combos for everything.. LCD's, Speakers, LED's, etc...

Tuck all the wires through their holes when you assemble the unit.

Step 8: Head TiltNothing makes Wall-e come more alive then his eye tilting. It adds a lot of character to his personality.

The eyes of the toy is tiltable by hand, but not automated. I put a drop of Krazy Glue to hold both parts of the eyes together. That way, the servo moves both eyes. Youmay want to not Krazy Glue the eyes together for an even funnier expression.

I mounted the smallest servo of the parts list to the neck. Of course I used a yellow zip tie and some hot glue gun ;)

Then use a peice of hard wire from the servo arm to the head.

Also, the electrical wires from the servo are very short. I used the servo wire/plug combo to extend the wires. And covered up the solder joints with shrink wrap.

*NOTE: Do not attempt to move this tiny servo arm by hand! You will break the plastic gears inside. Trust me, I broke one by trying. If the peice isn't lined up, simplyremove the arm and attach it in line. DO NOT TRY TO MOVE IT.

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 9: Circuit and ProgrammingThis part isn't the most difficult because I am using the EZ-Robot project. It is a robot controller board that connects to your computer over bluetooth. The robot boardcomes with software called EZ-Builder. The software allows you to control your robot without needin to program. You can also add a bunch of other features, includingvoice recognition.

Here are a few links to get you started..

EZ-Builder: http://www.ez-robot.com/EZ-Builder/

Add-Ons: http://www.ez-robot.com/Add-Ons/

Form for Questions: http://www.ez-robot.com/Community/Forum

How A Servo Works: http://www.ehow.com/how-does_4970258_how-servo-motor-works.html

Step 10: Your Robot!In autonomous mode, my Wall-e creates a 2 dimensional map of objects around him. This prevents him from getting stuck or backing into objects. The theory and logicbehind this technique is difficult and the implementation can be very challenging.

In addition to his enviromental awareness, his personality is also complex. His actions, movements and modes are not entirely random. He collects points and begins tofavour successful actions. Much like you would expect a pet.

It's taken years of observing, programming and pulling my own hair to figure a lot of this out. Start slow, and be creative. Figure out ways to add personality quirks to yourrobots that bring them to life!

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

Step 11: Battery.. POWER!Because my wall-e does have 6 servos and a microcontroller, his power consumption is high.

Due to size constraints, i was limited to a small battery.

My choise was a 2000mha LION 7.4v cell. LION batteries don't like to be drained, so be prepared for a low life expentency.

The 2000mhz battery gives my wall-e about 60 minutes of life between charges.

You can purcahse your battery at any Battery Depot or similar outlet.

Step 12: Enjoy!I hope you enjoy your new robot. For more information about my projects and robots, please feel free to visit my website at http://www.dj-sures.com/robots

 jomac_uk says:  Dec 19, 2010. 5:59 PM  REPLYWell i lost the one on ebay, and after a 2 hour search on the internet, there is NOWHERE in the UK selling the Wall-e U command..!

Are they still available in the States, and if so where?

 djsures says:  Dec 19, 2010. 6:19 PM  REPLYnot sure. sorry

 Onigirii says:  Jan 15, 2011. 12:55 PM  REPLYCan you tell me which programming skills I need in order to ,someday, one of these robots?

Thanks

 djsures says:  Jan 15, 2011. 1:13 PM  REPLYhttp://www.ez-robot.com says you can start off with zero programming experience and use the ez-builder software.

then, you can learn to "script" in the ez-builder... and eventually move to the ez-sdk for serious programming.

 jomac_uk says:  Dec 19, 2010. 8:25 AM  REPLYWith all the space available inside, why didnt you go for a bigger battery, or would this strain the drive train too much?

 djsures says:  Dec 19, 2010. 1:28 PM  REPLYit's a 2400 mha 7.2v battery. runs for hours. it's lithium-ion.there is absolutely zero space available. the tiny battery barely fits. there are multiple size toys, and the most common is the remote control wall-e (whichthis is not). check my youtube channel www.youtube.com/aliencurv for a video of my larger wall-e

 jomac_uk says:  Dec 19, 2010. 2:08 PM  REPLYSorry, i thought it was the remote control version, to be honest this is the first time ive seen a Wall-e and im pretty hooked!

 djsures says:  Dec 19, 2010. 4:18 PM  REPLYlol, he's pretty cool dude. that's for sure!

 fp_dahaka says:  Aug 25, 2010. 8:38 AM  REPLYwhy dont u add a video.....

 dxmmichelle says:  Sep 28, 2010. 7:59 PM  REPLYYes,there are many other microcontrollers to choose , i choose seekic microcontrollers.

 djsures says:  Dec 19, 2010. 1:37 PM  REPLYfor my most recent robots i use my ez-b that u can see videos and projects of on www.ez-robot.com .. or you can just see my robots on myw ebsite too :)www.dj-sures.com

 erin2003 says:  Sep 29, 2010. 2:03 AM  REPLYYou mean www.seekic.com ?

 jomac_uk says:  Dec 19, 2010. 7:24 AM  REPLYIm a bit confused here, are the servos actually used as the drive motors? if they are, are they modified for continuous rotation by removing the electronics?Sorry to seem dense!

http://www.instructables.com/id/Build-an-autonomous-Wall-E-Robot/

 djsures says:  Dec 19, 2010. 1:30 PM  REPLYthe instructions define the servos as "modified servos". check out my other robots used with modified servos @ www.ez-robot.com and my websitewww.dj-sures.com and youtube channel www.youtube.com/aliencurv

there is no such thing as a dumb question :)

 browaway says:  Feb 19, 2009. 10:14 AM  REPLYHello DJ...this looks like a great project for me and my son when I get back from deployment. I would like to purchase your card but couldn't get a messageback from you...Please help!

 erin2003 says:  Sep 30, 2010. 12:42 AM  REPLYIf you want purchase card ,I suggest you go to ChinaIcmart

 Jake_Rider says:  Jul 12, 2010. 2:42 AM  REPLYso here's all the instructions?

 ardebot123 says:  May 16, 2010. 4:56 PM  REPLYYou say use freeduino. I have an arduino duemilenove, could i use that?

 Demascus says:  Feb 14, 2010. 7:51 PM  REPLYproject looks good so far, I wanted to pass on that if your looking for motors with good gearing IE powerful, go to your local wrecking yard and take out themotors that move the seats   in the car. Powered seats,  Are amazingly strong use 12volts and have reduction gears in place.  Some even have flexableshafts. 

 chrisinsweden says:  Feb 14, 2010. 7:58 AM  REPLYReally nice, very cool  additions to a standard Wall-E. To take nothing away from your project, there is available a top-of-the-range Wall-E that does all thatyour one does and more. It is very expensive but I think it is worth the money and would make a fabulous bench mark to add more features to. It has avariety of sensors for obstacle  avoidance, obeys voice commands and mimics the 'real' Wall-E very well. My only complaint is that one of it's two sets ofbatteries drains very quickly and the battery compartment will not allow a larger one to be fitted.  I overcame this by adding a new box under the front of hisbody which takes any of the LiPo or NMh packs. I would be v glad to hear from anyone who has doctored one of these. Pimp my Wall-E!

 arhodes18 says:  Jan 16, 2010. 10:34 AM  REPLYThis is awesome!Does anybody have an estimate on how much this would cost?

 blottermusic says:  Oct 22, 2009. 11:20 PM  REPLYThere was a remote controlled Wall-e w/ voice on the market for $190.

 computer_guy says:  Sep 18, 2009. 10:04 AM  REPLYLmao. Lets try and put solar cells on him and another servo for it =D

 computer_guy says:  Sep 18, 2009. 9:57 AM  REPLYPoor Wall-e But we're going to make you better once we're finished with you >=D

 vernonlilly says:  Sep 18, 2009. 4:02 AM  REPLYI just want to say thanks, this is a awesome Instructable. I have made a couple of small obstacle avoiding robots and I'm working on a larger robot now.

 SepirothXD says:  Sep 17, 2009. 2:19 PM  REPLYdude,hardcore robot awesome great work have you ever tried to do an bumblebee robot?

 Foaly7 says:  Sep 11, 2009. 10:40 PM  REPLYCool. You might even pump this up with some commands you can give this robot by adding a microcontroller that can control the rest of the robot, andrewriting a software for giving your computer vocal commands to take commands for the robot to follow. Add a microphone in his head that wires up to themicrocontroller, and some sort of USB connection for adding more commands. Then you have an Assisant WALL-E.
