[MOC] LEGO Technic Wall-e

Recommended Posts

Hello, all,
I'd like to present you my third MOC: A lego technic Wall.E

This MOC was motivated by Lego ideas wall e 21303. Since there is hardly any room left for motorized aside from the 2 tracks, I decided to make a motorized technic version from stretch.
The goal is to make a motorized version as small as possible while packing enough motorized functions. The end result is a little bigger than the ideas one.

It uses 7 motors and 2 Sbricks in total. The Sbricks can be substituted by 4 IR receivers of course. Though some parts at the back of the model need to be removed for the additional receivers.
The motorized functions are:
2xL motors for propulsion (one for each track)
1xL motor for head rotation
1xL motor for head pitch
1xM motor for body lifting
2xM motor for the arms
1xAAA battery box

It has some manual functions too:
Like the ideas one, both arms can be moved back and forward.
Since its arms are based on the large LA, they can extend and retract.
It has three fingers on each hand.
Its cargo door can be opened by hand, however, the cargo space are taken by the battery.

Now, photo time!

I was trying to make it stand-able, but the result is not very good. The body can only be lifted by 4 units or so. The difference is showed below:

Here is it comparing with 21303:

Some details:
The cargo bay is a little crowded...

The motors used to control its head movement are part of its head structure. By doing this, 3 M motors, the battery box, the body lift mechanism and 2 Sbricks can fits in its body.

The underside is very simple:

Your Wall.E is a real cuty! In my opinion you captured the looks quiet well and the functionality is great. Especially I like how you have used the motors as an integral part of the head. Good idea! :thumbup:

And the presentation with your second Wall.E, aren't they sweet?! :wub:

Very nice, good mechanism and movement! But I find the back a little messy, you could maybe work a little on the design to smooth it, like the small brother!

Anyhow great work, bravo

Thank you.
When you say "the back", do you mean the back of the body or the back of the head or both? :blush:

Very nice Wall-E! Lots of function.

Too bad the video is blocked. Maybe you should redo it with different music. There is lots of music in the YouTube music library.

Thank you very much for the tips. I'll change the music when I get home today.

Thanks for the feedback. Will fix that and let you know. :wink:

Update:
Hi, JJ2 & Andy, I've changed the music, please check again if you can watch the video now.

Absolutely love it! I missed it here, thanks for posting to Rebrickable, that's how I noticed it. Must build :)

There are two things that I really like about this model:

1. The use of the link treads for visual purposes.

2. How you used the actuators as neck and arms themselves, not just to provide the movement.

With the neck, I think it's clever how you go for a simple design that is also functional and it looks good. I may have gone for some sort of lever mechanism... and got stuck on the way.

Thank you for your kind words.

I think the neck is a little too narrow/thin considering the looks. Maybe it will look better by adding some more beams. :grin:

This is an absolutely wonderful build and can't wait to start. I do have a couple of questions, though, and then I'm ready to start the build of this little jewel.

First, if I understand the s-brick concept, I need to download an app to operate the s-bricks. Could you tell me where I could go to access the app?

Second, I would like to add lights for Wall-E's eyes, but I don't know how to do that. Could you help me?

This is going to be a surprise for my grand daughter and if I can pull this off, she will think I'm a direct descendant of Merlin.

Keep building. You're really good!

Kind Regards,

Kind Regards,

Thanks and glad that this MOC will make you and your granddaughter happy. :blush:

For the Sbrick related, you can visit https://www.sbrick.com/ directly for help. Also, there is a long thread discussing it in this forum somewhere.

For lights in the eyes, there is enough room for the wires of LED. I don't have too much experience on studful building. The simplest way I can think of is to replace the black "eyeball" part with a transparent one.
