Introduction: K'NEX Motorized Walking AT-TE From Star Wars
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.

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:
- The motor drives the middle main shaft, which makes two blue rods turn ex-centrically around it.
- The blue rods on each side (left and right of the model) are mirrored.
- At the same time, via a Crown gear, blue gears and another pair of crown gears, the other two shafts are driven.
- These shafts make the same rotation as the middle shaft, but have a 180° lead/lag
- 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.
- 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...
