That’s actually really helpful, I admit an image might help to visualise some of the rack and pinion + gearbox stuff but I can easily picture the 3/4 cam wheel pressing down on a beam that is pushed upward by a medium-hard shock absorber. Pnuematics would be cool (perhaps even linear actuators could work as I do have those)? You’ve definitely given me some food for thought. edit: I’ve ordered some cams and hard shock absorbers. follow up question, the hips of an at-at from what I can tell move in a up down, level, down, (repeat) motion, to accommodate the legs bending (keep the at-at’s body level. Do you think it necessary to modify the cam to reflect this? Or should I consider that a relatively minor unnecessary aspect?

Hello, this is my first proper thread so forgive me if it’s a little amateurish in layout. With that said i’d like to begin by saying i’ve been working on this project on and off for a few years to get my 75054 AT-AT walking, having tried out the mechanism for the official LEGO walking AT-AT i’ve found that it is not stable enough nor satisfying. Since then I have been through multiple iterations of trying to get each leg moving but with only one off the ground at a time. As you can see in the pic from DK’s StarWars Vehicles book the mechanism for connecting and moving the lower leg relative to the upper leg seems to be similarly joined enough that it can be replicated using a linkage but making those linkages move in the correct sequence is the difficult part. The ankle on an AT-AT keeps three legs at a time level in the ground as well as lifts one other leg by moving it up when it takes a step. I have only ever found one person who has managed this in a non LEGO model so it’s possible: https://www.youtube.com/watch?time_continue=3&v=34tgu7ULkeM&embeds_referring_euri=https%3A%2F%2Fwww.google.co.uk%2F&source_ve_path=Mjg2NjY&feature=emb_logo That was 15 years ago. Here are some of my attempts: These two images use two sets of half beams to raise, lower and flatten the beams holding the leg, allowing up down movement, connected to the lower half beams are some linkages to move the leg back and forth, the fault of this one is it was not smooth nor stable. front Back (blue and red beams provide strength) This mechanism uses clutch gears going in a forward direction to move the bars down, half beams make them move up and down in turn, this reduced vertical space taken up, the failure of this is lack of connection points and strength as well as clutch gears probably not being able to support the weight. This was the most promising one, strong too but was unfortunately not quite walking in the right motion, it was not fully stable either. From further study I have noticed that the legs only bend in one direction so i’ve placed a stopper on each one to mimic this, I imagine this will add to the challenge. But i’ve seen people on eurobricks work magic with technic so I figured I should ask here for some help to find a solution.

Hello, my name is *checks username* BrickBear! I’m a big fan of StarWars, Batman and Technic. My main reason for interest in Batman sets is I’m an artist/illustrator with a love of comics and especially dc. So it stands to reason that I enjoy collecting the various vehicles, villains and heroes. I’ve illustrated 3 short unpublished Graphic Novels/comics, some completely illustrated by hand. As an artist I consider Lego an extension of “my practice” and I actually was one of the winners of this competition (although I think half the competition were disqualified for not fulfilling the photograph requirements so there’s that): https://www.lego.com/en-gb/my-starry-night-lego-build. As well as my creative side I also have a very mechanical side which is why I also enjoy technic, for the past six years I’ve been fiddling about with two Lego Technic sets, airport fire truck and 6x6 all terrain tow truck to make a crane and digger. I always try to make things as compact as possible and often things take me many iterations but I think I’m arriving at something to be satisfied with, I also enjoy mini Lego technic sets as I like to challenge myself to come up with a third model. I always give myself a similar challenge when it comes to Star Wars sets, I’ll often find there’s an aspect missing and see if I can figure out a way to include that aspect using just the pieces that came with (like retractable landing gear or more space in a cockpit). One modification I’m particularly proud of is this function I added to the 20th anniversary slave 1, I added manually opening side panels that can be closed seamlessly with the push of a button, oh! and gravity affected rotating guns. My current project is attempting to emulate the walk cycle/gait? of an AT-AT, I’ve been through many iterations and decided it might be time to seek assistance. I look forward to participating on Eurobricks after 10 years of just reading and learning from the experts on here.

Hello, I think I’ve been using eurobricks for like 10 years now, finally joined because I have a big technic project I’ve been trying to figure out for a few years and after many iterations I release I’m kinda stuck and could do with some fresh eyes. It’s all about mimicking the AT-AT walking gait Also, testing testing 123
