Introduction: K'NEX Motorized Walking AT-TE 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 …

In this ible I will show you how to build a K'NEX walking All Terrain Tactical Enforcer (also known as AT-TE), from the Star Wars movies, and Clone Wars series. The model is fully motorized and can walk over several terrains such as: Vinyl and laminate floors, carpets and not un-important: bedsheets

The model is about 50 cm long and built from 810 K'NEX pieces. The model is motorized which means it can walk realisticly in a straight line. It has a big cannon on the top that can rotate 360° and 6 other cannons that can also move slightly.

The building instructions are devided into the following steps:

  1. Parts needed
  2. Walking Mechanism
  3. Adding Legs
  4. Front end
  5. Armouring the AT-TE
  6. Adding Cannon & Finish

Wheels:

  • 2x Hub/Pulley Medium

Step 2: Walking Mechanism

The walking mechanism is key to the movement of the AT-TE. It's not as difficult as it looks and I will try to explain how it works:

  1. The motor drives the middle main shaft, which makes two blue rods turn ex-centrically around it.
  2. The blue rods on each side (left and right of the model) are mirrored.
  3. At the same time, via a Crown gear, blue gears and another pair of crown gears, the other two shafts are driven.
  4. These shafts make the same rotation as the middle shaft, but have a 180° lead/lag
  5. This means that always 3 feet are on the ground: front left, middle right and rear left. The others are in the air and making a pace.
  6. To make a pace, the legs need to be lifted. This is done by creating a point that can move up and down, but not sideways. This is above the middle shaft.

If you have questions on how it works, feel free to ask in the comment secion.

Step 3: Adding Legs

The feet gave me the boundairies to how big the model would become. The middle feet are slightly bigger, and I resolved that in having grey connector clips as toes and a wheel hub as spherical centre. The typical armoured joints are made by another set of wheel hubs.

For the smaller legs, I had to scale things down, which wasn't easy. It took me 4 designs to come to the final solution. Here, grey gears form the joints.

Step 4: Front End

Right after making the walking mechanism, I designed the drivers cabin and the front end. I tried using orange and red, but I found these colours to be too bright. Instead I used the brown.

For the cannons, I came up with a ball-joint connection that fits through a 3D-connector's slot. Some armouring is already done, before the front end is installed, by flipping it over to the front.

Step 5: Armouring the AT-TE

From the start of building the AT-TE, I was looking forward to the armouring: Because it would be a challenge to get the angles of the different plates at a good angle. I'm lucky to have many K'NEX silver panels, but I never used so many in one model.

Attaching it to the model was also a lot of fun, I had to find ways to connect it to the walking mechanism/frame. But while building, I left some connector places open, so it was easier to do.

Step 6: Adding Cannon & Finish

The cannon was not easy to design, although relatively simple. I saw some disks at the side, so I added K'NEXmen head instead. Also here there are two mini panes that mimic the original shape. If you use your imagination, there's even a little stool where the gunner can sit :)

After building this, I feel more confident in building an AT-AT Walker >:D That's right, that is still on my list to build! Check out what more: https://www.instructables.com/id/KNEX-Star-Wars-Shi...

I hope you enjoyed reading my instructable!

Thanks and maybe the Force be with you!

    I just finished building this and I'd first like to say it is amazing! It looks good, and I can tell once I figure out why this weird problem is happening, it'll walk amazingly too.

    Problem: For some reason, when it begins walking, it starts to "stutter" per say. The gears all lock up and it begins making this really bad noise. I have no idea what is wrong, but when I hold it up in the air and then turn it on, it walks fine.

    Any feedback is appreciated! I have attached a video of it making the sound. Ignore the non-matching colors of pieces, I couldn't be bothered to buy the actual colors of pieces needed.

    Edit: Sounds like it could also be a problem with the motor? I have no idea for sure but I would really like to fix this ASAP.

    Sounds like something is stuck and can't move. Perhaps remove the "armour", and see if it walks without it.
    If it doesn't, your gears might be too tight. Try to loosen them up as much as possible.

    Alright, I'll try this out and see if that works. Thanks!

    Hi I am trying to build this model, but the motor doesn't seem to be strong enough. Any suggestions?

    That's a pity. Here's some troubleshooting:
    1) Are your batteries fresh? Old batteries might not deliver the power needed
    2) Try to make sure that every rotating axle can move freely without too much friction. I personally always check this while building.
    3) See if some part gets stuck. What you can do is to remove the "armour" And heavy parts, and see if it walks. If it doesn't, I think your problem lies in 1) or 2)
    4) Are you using a motor with red or silver battery box? Older motors could be a bit weaker because they use a worm gear, this generates more friction in the motor.

    Feel free to send any pictures or videos, I hope you can get it to walk!

    Thank you very much! It's really fun to let it walk.
    Idea for improvement: Install 2 motors so it can make turns :D

    What is the difference between the grey gears and the yellow gears (besides color)?

    Besides colour, there's no difference :)
    Even the friction (very little) should be similar.

    How are your builds coming along? Have you made some progress? :)

    Good work as always Gworks, yet maybe another one to build in the future, I haven't even started yet on the Millennium Falcon and Tie Fighter cause I'm still waiting for the special pieces that I don't have are still in the post.

    Really nice to see someone building something out of K'nex that isn't a gun, or a structure/building. I build Star Wars and Star Trek models out of K'nex as well. Great job on this, very impressed!

    Cool!
    Yep, seeing that the gun-ratio on Instructables was high (too high in my opinion) I decided to do what others didn't. So far it paid off :)

    I really hope to finish the Slave I this weekend ;) Then I reached my quotum of 4 ibles in April, and can retire for a while :P
