Introduction: K'NEX Motorized AT-AT From Star Wars

About: Hello! I'm a maths tutor and primary school teacher and have always had a passion for making things. This started at an early age with LEGO and K'NEX. I share my K'NEX projects on instructables for others to …

"Fire at target with Maximum Firepower!"

- General Veers

In this Instructable I will show you how to make the All Terrain Armoured Transport (AT-AT) from the Star Wars universe! The AT-AT is a walking vehicle used in assaults. Due to its strong armour it can take many hits. In the movie Wedge takes one of them down, with help of the harpoon on the Snowspeeder. I've long wanted to build this model, but wasn't sure if I could get the walking mechanism right. Luke destroys one with a detonator.

This model is about 45 cm high, 9 cm wide and 50 cm long. It comes with motor, gears and movable Laser cannons in the head. The model took me about 1 week to build and 10 hours of video shooting and editing.

The steps are like this:

  1. Parts Needed
  2. Walking Mechanism
  3. Building the Head
  4. Adding the Head & Armour
  5. Building & Adding the Legs

Here you can see a video of the model, together with my Snowspeeder:

Step 1: Parts Needed

Individual K'NEX pieces can be bought at:

  • KnexUserGroup (UK)
  • KnexSpares (UK)
  • Knex.com (USA, very limited selection)

Parts required to build this model

Rods:

  • 110x Black rod (16 mm)
  • 94x Silver rod (32 mm)
  • 13x Blue rod (54 mm)
  • 3x Dark Grey rod (86 mm)

Connectors:

  • 1x 8-way connector Black
  • 6x 7-way 3D connector Blue
  • 86x 4-way 3D connector Silver
  • 49x 5-way connector Grey
  • 21x 3-way connector Dark Grey
  • 7x 2-way (long shape) connector Brown
  • 14x 2-way (V-shape) connector Grey

Clips:

  • 54x Clip with hole end (1-way connector)

  • 9x Clip with rod end Silver (Y-clip)
  • 6x Hinge part Black
  • 13x Clip Ball end Black
  • 3x Clip Socket end Black
  • 9x Interlocking pin Tan/Bronze
  • 14x Clip Blue

Wheels:

  • 1x (!) Wheel open Centre Black (25 mm) (! not on Image !)
  • 7x Hub/Pulley small (37 mm)
  • 4x Hub Racing wheel (37 mm)
  • 4x Hub Racing wheel (50 mm)

Gears:

  • 3x Gear small Dark Grey
  • 3x Gear small Blue
  • 3x Crown gear Silver

Panels:

  • 10x Silver tri mini
  • 2x Silver tri small
  • 2x Silver Square small

Other:

  • 1x Elastic Band 1 cm / 1/4" Diameter
  • 20x Blue Spacer (½ width)
  • 4x Silver Spacer (1½ width)

Step 2: Walking Mechanism

In this step, you will build the Walking Mechanism of the AT-AT. You build two sides that hold the Gears within, then you attach the ex-centric rods that make the legs move and walk.

Making this thing walk isn't easy. Even after building it, it took a long tweaking time to get it right. Better walkers can be made, if theming isn't important.

In the next step, you build the head.

Step 3: Building the Head

In this step you will build the laser cannons hanging below the head, then you add the neck, sides (plus cannons), visor and the top. This can be opened

The head was the second thing I made. It was pretty hard to get that visor right, since it's iconic and looks "evil". It gives the AT-AT its fear-factor. The cannons can be swiveld by hand.

In the next step, the head will be attached to the body.

Step 4: Adding the Head and Armour

First you'll add the head to the body. I had trouble finding out how I could do this, because the space is tight because of the walking mechanism that moves in this area. Then you add the top, and side armour. I needed two iterations for that.

In the next and last step you make the legs and attach them to finish your AT-AT!

Step 5: Making & Adding the Legs

In this step, you'll build 1 foot, which you should copy 3 more times. Then you will make the lower part. These are all exact copies. The upper part has 2 versions, left and right. But there final legs are unique. Pay close attention!

If you have trouble, you can always ask me in the comment section. I'm glad to help.

Once you've finished making the legs, you attach them in a unique way that I discovered. It uses "Y-clips" and makes it possible to keep the width of the AT-AT as slim as possible. If the legs are attached, you're ready to test it! You might need to tweak the gears so that the walking pattern becomes good.

I hope you've enjoyed reading or building my model. If you do, leave a comment!

May the Force be with you!

Question 1 year ago on Step 1

First off, amazing build! It works really well, and is awesome to watch, however, I have noticed a few problems.

I have had this for a few years now and have had to repair and rebuild a lot of things due to building error (while I was building it), user error, but also some general problems of which I have no clue how to fix. Here are some (maybe all) of those problems.

1. I noticed the walker likes to try to walk right, and can't seem to go straight. I'm assuming this is normal and probably due to the weight being off to the right side of the walker? Is there any way to fix this?

2. The legs feel very loosely attached and not very strong. I've had to save it from falling even while on a very flat surface.
2a. While it is walking, it's back leg (the one not moving) likes to bend backwards, looking like it's about to fall over or something. I'm not sure if I rebuilt something wrong (I've had to repair this thing like 50 times due to a number of problems) or what the problem is but I'm hoping to find out.

That's about it at the moment, I'll probably think of some others but all around it's an amazing thing and something I would recommend building. I don't know, but these problems could be entirely my fault. Also, I know the other comments are 5 years old but I figured I might as well try. 😂

Thanks, and again, great job!

Hey! Thanks for this extensive message about the AT's problems. Well, in short: They are all common problems I had myself as well. The AT-AT just *isn't* a good walker, unfortunately!
Point 1. is correct: It has a tendency to go to either to the right or left. Not much to be done about that, really. I don't know if it's due to the weight, could very well be.
Point 2a: Leg connection shouldn't be an issue. If you connect the Y-clip-1-way connectors in the correct way, they shouldn't come off easily!
Point 2b: You mean the "knee-joint" going backwards? Yeah, that's also a known issue. My brother built the model for a live event and got it to walk better, by limiting the movement a bit more. I'm just not sure how he did it. Might wanna check out this video of the model actually walking: [Time stamp 3:39]

The model just isn't the best walker and surely has balancing issues. I hope it still looks good as a shelf piece. But also I get friends that want to see it walk and then face somewhat of a disappointment. Might revisit the model in the future!
I'm very grateful for you people who build my models, it's what keeps me going :)

Thanks for getting back to me, even if it is a number of years late! Also, out of curiosity, are you still trying to build the AT-ST (motorized or not) walker or did you scrap that idea?

Edit 1: I noticed in the video that there is an AT-ST, but there is still no instruction for it, and also it was on a stand, but at least it's legs work. Any plans to release this (assuming it's your work)?

Edit 2: Also also, there was a Y-Wing in the video that is also not released. Do you plan on releasing that one as well sometime in the future (again, if it is your work)?

Your comment was made 4 days ago. If you wanted help sooner, you should have commented earlier.
The AT-ST is my design and still sitting in a box ready to be made a video, instruction etc of.
The video of the Y-Wing is out, the instructions just haven't been made (am halfway, but stopped half a year ago. I'm better off doing them all over again but meh)

Hola José, gracias por tu comentario :)

Uy, me parece difícil encontrar los piezas de k'nex allá. Estoy pensando en vender los modelos (como un set) con piezas que ya tengo y que son más fáciles para mi para comprar. Pero aún no he realizado algo así.
Así podría enviarte un set completo. Solo, las piezas no son barato y el envio desde holanda tampoco :(

Siempre puedes buscar en Amazon y Ebay. Quizá puedes conseguir un set con piezas metálicas en MercadoLibre. (Temas ISS o MechWarrior)

Me gustaría ayudarte en una forma. Hazme saber que piensas y si conseguiste algo en esas paginas.

Saludos también, amigo

Yeah the AT-AT's look good in the trailer. I hope they'll 'win', just like in the battle of Hoth. Perhaps we will hear how the name's pronounced. It appears that "@, @" is the correct pronounciation, but I still call them "Ah-tee-ah-tee's" myself.

Have fun watching Rogue One, I don't think I'll have the opportunity to see it.

Exactly, right? I mean, the part about pronunciation. You know, funny thing, I checked them up, they're actually called AT-ACTs, not AT-ATs. It stands for All Terrain Armoured Cargo Transport.

Yes, but check the date of that comment, it was before the movie was launched: I didn't know what they were :)

I'm not a fan of DVD's, they take so much space you know. Anyways, I did build (or try to build) something like the Death Star (and it's on my list secretly) But I need a lot of silver connectors for that. Thousends xD If I do make the DS, then it's going to be big, and it's going to be special.

Ok fair do, sorry to be nitpicky but I have notice a mistake in the description where it says Luke took down two AT-AT's in the ESB when in fact it was only one as Wedge Antilles had taken down the other.

I was doubting... Wedge took it down, but Luke shot it, no? I was wrong.

I see it Zombiekiller, good work spotting my mistake ;)
