Yet Another Wall-e

So I built my Wall-E months ago after receving it the day after I finished Metal Box-Bot, but I haven't got around to uploading my project until now.

While I was happy to receive what I thought was the U-Command Wall-E, mine seems to be a different model as it's much smaller than many I see on the forum including DJ's "Real Wall-E". I figured "oh well. Nothing I can do about it now".

While I did run into a few snags with the size I was able to build what I think is a pretty successful Wall-E. Especially since I had to meet my wife's deal of:

"I'll get you an EZ-Robot kit for your birthday ONLY if the first bot you build is a Wall-E. He's cute!".

So here he is:

Destruction begins!

Who need's cheap plastic gears? Not this guy! But I'll hold onto them in case:)

User-inserted image

Careful cutting. Gotta make those continuous servos fit and hide.

User-inserted image

That should do it. Just enough left to hide the servos from the front.

User-inserted image

Servos in place.

User-inserted image

Servo attached to the drive wheel. I hope it's centred!

User-inserted image

Eye looks a little too small, but I'm determined to make it fit!

User-inserted image

Crooked, but it will have to do. Can anyone spot the mistake in this picture? Yup! The camera is upside down. I dind't notice of course until he was nearly put back together. Thankfully that wasn't hard to fix!

User-inserted image

Webcam eye is now installed. Right side up that is... Oi.

User-inserted image

Cut out the arms to fit the servos.

User-inserted image

Install the head servo. thankfully with screws. I try to use screws where possible. Screws > Glue

User-inserted image

Arm servos installed using screws as well. Body assembled and battery pack tucked inside. Unfortunately some disassembly is required to replace batteries, but I'm okay with that. I'm just glad is fit into that little chasis!

A closeup of the snug fit inside. No room for the EZ-B, but I was able to attach it to the bak using a single pre-installed screw and hole. It swivels nicely in order to tuck all the wires inside.

User-inserted image

And there we have it! His arm fell off just prior to this picture and I realize now that I don't have anything showing the attachment of the arms but it's exactly the same as DJ's Wall-E.

I will post a couple more pictures showing the profile of Wall-E all together when I get a chance.

So everything was able to fit. I have horizontal rotation for the head, but no vertical. If I do decide to install vertical, I will need to use a mini servo. I just don't know how much room I'll have with that tiny head.

Also I do have one problem. The left track is WAY stiffer than the right. So the rubber doesn't roll around the wheels properly. Up until HiFive was released, my Wall-E had a severe circle walking problem. With servo speed control I was able to slow down the right track, but man is he slow now. It's really too bad as he turned out really nice otherwise.

I'll post in the general discussion to see if anyone has any spare tracks for my size Wall-E. I have a couple pics of his measurements I'll upload if I have a chance.

So all in all THANK YOU DJ for this great experience. Once I have my Wall-E and his personality perfected, I plan to move onto bigger and better. And thank you to the community for the helpful hints and tricks.

I have bought two U commands and both are different. The small wheel on the base is on the back on the model I did my Wall.e with and in the middle on the one that is waiting to be done. On the small interactive one (which looks like the one you have) the remote was a dinky little thing, forward backward speak and two other buttons. The U command one has a dump load of buttons that fail to impress:(

I must say, when you slap an EZ-B up Wall.e's bum he never fails to entertain!

I think this toy is the Interaction Wall-E

I just picked up one of these for $10 - pretty good deal if the retail is $120. No remote control at all and I guess most of the goodies come if you also have others in the family like an interaction E-Va.

He is about 5/6 the size of u-control Wall-E but the details are quite similar. (I have just unpacked him at work and won't turn him on till I get home.) He has a more articulated neck, with a proper hinge bend in it - too early to say if you could easily automate it.

There is no drive for the tracks at all - just a single axle running across under the main case.

This clip -

- is definitely the one I have.

There's also this guy for about $50 retail, but no info on what he does if anything. Wall-E 'figure'

Here he is alongside u-command Wall-E -

  • probably more like 4/5 size.

And a view from the rear -

  • shows the driveless axle.

I think the gear hubs might only detect the toy being rolled back and forth to trigger a response - he's quite chatty.

The battery door hides 3 AA cells horizontally.

Now - dare I take to him with the screwdriver?

(No rush - plenty of other bot-work to finish first.)

i have both of them to modify,you job on your looks good, looking to do the same with some other added stuff,but using almost no hot melt glue when you want to replace or fix a robot with hot melt its a little hard so i use brackets or pieces of plastics super glue to the robot then use screws to mount the servo's same with mounting the web camera right working on my roomba project,then a little more work on my brookstone rover project then maybe omnibot 2000 or wall-e since all my parts came in

Hey guys,

So I tried the power steering steering fluid as recommended. I left it for one day. Felt it and decided to go for another day.

The verdict.... Nothing. No change at all. Well except that it is a little shinier. Oh well:( I was thinking of tearing him down and making something else. Something with less personality and then DJ releases all these cool new features like RSS feeds.

Now I'm toying with the idea of modifying it to just use the round wheels, but glue the tracks to the front permanently to give the illusion that he still has tracks at least. I just don't know.

@thefoolmonty & @robotmaker

as long as you have 2 god maluable tracks, I say go for it. It's a bit squishier and you will have to likely strap the EZ-B to his back like I did, but he makes a great little compact wall-E! Just be glad you didn't spend $125 on it like I did thinking it was a U-Command... That will teach me to be more patient!

FYI Cost breakdown for me was messed: item: $60.00 shipping: $24 UPS FRIGGIN BROKERAGE FEE: $41 !!!

Lesson here is if you live in Canada, DON"T let a US seller ship via UPS. Try your luck with USPS. Much less likely to get charged for brokerage and if you do it's like 5 or 6 bucks.

PS: @thefoolmonty That is exactly the one I have I believe. Giv'er a go! :D

@daman ,whats wrong with your tracks,if not in good condition there is liquid rubber or spay on rubber that would help you fix it i know whats it like to get parts or robots from other countries,when i check to buy a ezb from DJ site postage very high

#15  

Don't forget the little hidden feature shown in the video - that little pull down flap at the front could be used for accessing the internals after a little cutting.

I just missed out on picking up another one of these for $10 + postage -I'll continue to keep an eye out for them.

For rubber to restore some of the elasticity and also good for plastic I use Mothers Back to Black. Made for car bumpers . Looks like 50w Armor All! The best stuff I have ever used. I do auto upholstery and also have restored several motorcycles . I use this stuff all the time .
