intro: Wall-E RobotThis is my Wall-E project that I am currently working on it is 150mm x 150mm x 160 high, it uses a pair of Mattrackshttp://www.litefootatv.com/html/litefoot_in_the_news.htm for motive power and two robosapienV2 hip motors. It will be controlled by a BS2P40 stamp CPU and will havethe following functions described below.

I build robots quite prolific but my let down is programing "hopeless but learning" I have a friend at http://www.robocommunity.com who is programing it for me, From thisI hope to learn how this program is put together and eventually program myself. We are in the progress of designing the H-bridge for the motors using the L298 chip, Thehead is finished apart from his adorable eyebrows which http://www.musclewires.com/shapememoryalloys.shtml wire or Muscle flex and pan/tilt has been run.

The main reason for building this project was to see if I could use parts from my stock of components that I have lying around my basement and electronics room, Theonly thing so far that I have had to buy is the Mattracks , uOLED screen and L298 H-bridge ic. Which GWJax is sending me. I was inspired to build this project afterseeing a Pixar demo video and thought WOW what a neat bot to build.

I have been in R/C scale and other unorthodox aircraft for over 30yrs and modeling is my passion, so this comes in handy when creating something like Wall-E. I hopeyou like how it is coming along. I would also like to add that GWJax has been an inspiration to me on the programming side.The main construction of Wall-E is 5mm liteply, sides,front,back and top, with 2mm balsa cladding on the sides with some 1.5mm ply to form the raised panels. Rivets were made using PVA glue watered down40% and applied to the required area's with a sharp pointed rod, One dip will give you 3 rivets. The arms were constructed out of 1.5mm ply and balsa, and uses 4 of myTechnics air rams back to back, The fingers were modded Technics angle beams covered in 1mm ply for the sides and balsa top and bottom.

The base is constructed out of 5mm Acrylic sheet as this is good for boring holes to mount your fittings. the head H'mmm a real challenge here, I had to draw it out first toget the pear shaped eye right then work from there. The main eye tube was a pair of alloy pill containers which worked out to be the right size for the head. The BlueLEDs x 6, 3 in each eye are mounted on a 5mm acrylic disc and inserted in the tube about 2/3rds down, then another Acrylic disc in front with the ping sonar in eacheye.The ping sonar is from TX and RX had to be removed from the board [tricky and an extension lead [screened] run from the board to the Tx and RX in each eye. I wasnot sure at the time if this would alter the characteristics of the range, but after testing this was unfounded.

The eyes light up at present using a circuit which has a CDS cell and when you switch the lights of the eyes come on, GWJax may code this to work also with some otherfunctions on Wall-E.Wall-E was finished with off the shelf spraykote enamel cans, grey primer, followed by antirust primer, then layered with yellow, rivets applied, thensliver over the rivet area, followed by an airbrushed rust over the rivets. The whole body was then rubbed with scotchbrite pads until the rust and some silver wasshowing through, then airbrushed with a mix of satin varnish and grey primer to give Wall-E that weathered effect.The head was done in a similar way but with differentcolors. Phew, I think that's it guys. Check out my web site.http://robosapienv2-4mem8.page.tl/ Robotic Madness

You are doing a GREAT job!For anyone who is interested, we are building full size Wall-E's at The Wall-E Builder's Group www.Wall-EBuilders.comwww.Wall-EBuilders.com where4Mem8 is not just a member, but an inspiration!!!I want your design for the eyes on my Wall-E!

4mem8 says: Sep 11, 2008. 11:15 AM REPLYWallebuilders: Hey how are you, Sorry I have not been around on your site, Have been very busy with some new robots, I will get back to your site soon,you ar welcome to my eye design for your Wall-E.

DarthVader says: Jan 28, 2009. 4:41 PM REPLYy'know, they know that you replied to them when you click "reply"

Mattrox says: Sep 23, 2008. 12:28 PM REPLYcooldo the arms move?

4mem8 says: Sep 23, 2008. 11:01 PM REPLYMattrox: Yes, the arm move up and down, The door comes down, The head has pan/tilt, Ultra sonic for the eyes and 4 IR sensors around the base foredge detection and an IR sensor between the eyes for long range. Also a uOLED screen with moving slide show and a LED battery meter.


Mattrox says: Sep 24, 2008. 2:17 AM REPLYcool

knive05 says: Sep 28, 2008. 9:49 AM REPLYcan you teach me how to create a program for this wall-e i use it for my thesis pls help me thank alot

4mem8 says: Sep 28, 2008. 10:10 AM REPLYKnive05: Sorry I cannot do that for you, The program is still being developed by GWJax, and he has the final say.


unbentcrayfish says: Dec 2, 2008. 7:35 PM REPLYYou have no life. But, it is still cute...

4mem8 says: Dec 2, 2008. 8:44 PM REPLYunbentcrayfish: It's quite clear you do not know me well enough to make that call.But i agree it is cute.



Owen-mon-82397 says: Dec 7, 2008. 4:23 PM REPLYcongrats on highest ible! :D

4mem8 says: Dec 7, 2008. 8:21 PM REPLYOwen-mon-82397 Thanks for the congrats.


Plasmana says: Dec 7, 2008. 10:25 AM REPLYHaha, my plasma speaker is behind you... :-)

4mem8 says: Dec 7, 2008. 8:27 PM REPLYHey Plasmana. Correct not far behind.


Plasmana says: Dec 8, 2008. 2:23 AM REPLYYeah...

Anthony312 says: Dec 2, 2008. 6:31 PM REPLYHey 4mem8 remember me? (If you dont my comments are below)They made a wall-e toy that could transform into a cube. I guess they beat me to it.

4mem8 says: Dec 2, 2008. 8:50 PM REPLYAnthony312: Got a link to it??


Anthony312 says: Dec 27, 2008. 9:08 PM REPLYno I just saw a commercial on tv and a toy review on youtube. It's not that great anyway. its spring powered not motorized and the head, arms, andtracks are smaller than normal in proportion to the body. you just press a button and the head, arms, and tracks come out, then you just push themback in.

evilgenius 398 says: Aug 18, 2008. 1:38 PM REPLYwhere did you get the treads?

4mem8 says: Aug 22, 2008. 2:55 AM REPLYevilgenius 398: Radio shack has them fir about $12 a set. They are from a Hummer R/C vehicle.


evilgenius 398 says: Sep 3, 2008. 10:18 AM REPLYcan you get them online?what are the dimensions?


4mem8 says: Sep 3, 2008. 10:49 AM REPLYYes, from Radio shack, They are 150mm long x 50mm wide x 100mm highCatalog numbers are Left/ RSU 12458907 $11.69 & Right/RSU 12458923

evilgenius 398 says: Sep 3, 2008. 7:39 PM REPLYthanks

Anthony312 says: Jul 10, 2008. 7:19 PM REPLYwhat you could do is place some cameras in the eyes so u can see what wall-e sees.

4mem8 says: Jul 10, 2008. 8:55 PM REPLYAnthony312: i could have and that would have been cool, BUT, I decided to insert Ping ultra sonic sensors instead as I though collision avoidancewould be better option. Thanks for you interest.


Anthony312 says: Jul 15, 2008. 10:06 AM REPLYok i can understand that. But i saw these cool cameras that would fit in wall-e's eyes and still leave room for motors and wires and stuff. they're only0.3 in. by 0.3 in. by 0.4 in. And when i watched some wall-e videos closely, i found out that the lense part of wall-e is hollow, which means it can beuse for zoom and focus. this also helps when wall-e has to turn into a cube.

4mem8 says: Jul 15, 2008. 1:00 PM REPLYThat would be cool also, but I had no room left after installing the Blue LEDs and ping sensors.

Anthony312 says: Jul 15, 2008. 11:13 PM REPLYoh...ok then. but im going to build my own wall-e robot, and im going to use cameras (and if there's room ill even do that LED and sensorthing like you did) and it will have one special feature that no other wall-e robot (that ive seen so far) has ... it can turn into a cube!

Anthony312 says: Jul 15, 2008. 11:15 PM REPLYthough im working on how he would be able to compact trash (thats for later).

CapnTac says: Jul 18, 2008. 7:05 AM REPLYI hope you put up an instructable for it! Good luck making him roll up into a cube, that seems really hard. For the trash compacterthing, simply put metal squares on pistons inside of him, then when you put the trash inside of him, you could activate the pistons, andhe would compact the garbage. Just a brainstorm.

Anthony312 says: Jul 21, 2008. 7:16 PM REPLYBut the Metal squares will crash into each other, and plus they will leave no room for the rods that will bring wall-e's tracks upwhen he has to turn into a cube. plus the metal squares wont leave room for the tracks themselves. Anyway it doesn't matter, idont care about the trash compacter as much as i want wall-e to go into cube form. Thats what i want most.

4mem8 says: Jul 21, 2008. 9:47 PM REPLYBefore I answer your question, How many robots have you built??

Anthony312 says: Jul 24, 2008. 3:36 AM REPLYI have never had the time or the money to completely finish a robot, but I have made many electrical circuits andcontraptions with the parts I have laying around on my desk. I don't have enough money (or time) to buy all the parts I'veneeded to complete a robot, and I already have plans with what to do with the cluttered junk on my desk (I'm going tocombine it all into one electrical contraption) so I'm out of parts basically. I also don't have the time to finish a robotbecause I'm very busy with school and homework and reading books and watching TV and playing on the computer (likeI'm doing right now). So right now I'm just researching and making plans for all the robots I will be building in the future(which of coarse includes wall-e) and making sure they're all foolproof. I've lost count with all the plans for the robots I'mgoing to build. So I'm waiting until I have the time and the parts to finish a robot.


4mem8 says: Jul 24, 2008. 4:46 AM REPLYGreat, pleased you are into robots, Take your time and do it right.

Anthony312 says: Jul 26, 2008. 10:08 AM REPLYThanks. Now what were you going to say earlier?

4mem8 says: Jul 26, 2008. 12:29 PM REPLYOk, What I am about to say is [Please don't take this the wrong way] When you have finished building a [A truerobot]robot, from start to finish including programming you will see that it is NOT easy to do, Wall-E is a verycomplicated robot to build and to do what you are thinking of doing is pretty much on the top end scale to getworking, I will not say impossible because there is no such thing as impossible, BUT what you are asking isgetting pretty close and if you pull it off I for one will congratulate you Anthony312. Good luck and I look on withinterest.

Anthony312 says: Jul 27, 2008. 10:57 AM REPLYI know how hard its going to be to build. But don't worry, i've got a whole lifetime to build it. It will be finishedsooner or later...and thats a promise!

Anthony312 says: Jul 27, 2008. 11:03 AM REPLYBut lets get back to what i was saying earlier. do u have anything to say about the comment i statedafter yours to CapnTac (its the comment at the bottom of this conversation) and if you do, please replyon that one, this one is getting cramped.

Anthony312 says: Aug 4, 2008. 11:59 PM REPLYhello!?!?!?! Anyone there! 4mem8 why haven't you answered yet?!?!

Anthony312 says: Aug 14, 2008. 10:31 AM REPLYStill no reply...are you ignoring me or something?

4mem8 says: Jul 18, 2008. 12:57 PM REPLYCapnTac: It will be harder than he thinks, With all my electronics,motors,servos and batteries you could not fit a fly in there.

Anthony312 says: Jul 21, 2008. 7:39 PM REPLYI know exactly how hard this build is going to be. I am well aware of the space effiency of wall-e too. The reason you have noroom is the size of your motors and servos and maybe even the electronics. They make smaller motors you know. and why dou need that huge gearbox attached to your motors when you can just connect the motor directly to the mattracks without thegears. and you can use a smaller recorder for wall-e's speach. When i examined wall-e the eyes only take about as muchroom as the bottom of the solar charge level screen up, and the tracks take as much room as the hollow trash compactorinside wall-e, which happens to start from the bottom of the solar charge level screen down. And his eyes are not as wide asthe entire of wall-e itself, as a matter of fact it is 2 wall-e arm widths smaller. so as far as i can tell, wall-e turning in and out of acube is plausable. There is even room for the solar pannels (they can replace the battery if you charge up long enough) andone or two small microchips fit (you can use 1 for speech and 1 for charge-up panal).
