[MOC][Noob] Simple Walker

[Bob De Quatre]

Hi Technic builders,

I wanted to build a simple walker, so I looked on the internet for simple mechanisn that I could copy. I saw Sariel's walkers, and some others, but they always needed technic parts that I do'nt have, or at least not in the required quantity. But I got inspiration from all those builds and started building a simple mechanism, on which I claim no partenity! 

 

As you can see on the video, the movement isn't really fluid. That's mostly due to the legs I used, which are too wobly to hold the weight. Also the feets slipped on the paper sheets. A third pair of legs would solve most of the problems... As I wanted the walker frame to remain as small as possible, I used only one motor, and thus making the walker only able to move in straight line.

I made a quick LDD file and put it on my website, if anyone want to take a look at it.

Maybe a "simple walker" but I think it is just awesome. Would like to be in there BTW, would make me sea sick...haha... ;-)

simple i wouldnt say to this. simple genius maybe

[BrickbyBrickTechnic]

This is genius!

[Bob De Quatre]

Thanks guys, but still, it's a simple build compared to the incredible things you build 

[efferman]

To build small with functions is a category which is not mastered by many people. Building massive things with functions is much easier.

Impressive! Aesthetics are great, and it DOES walk, even if its not perfect. Good start!

[2LegoOrNot2Lego...]

I really love it and there is no need to call it "simple". Like @efferman wrote simply genius that is what it is!!!  And there is no reason to compare either for me we are all creative in our own unique way...

Cool sci-fi build.  It walks and a good starting portal into other motorized builds. 

 

[RohanBeckett]

maybe smaller leg movements (less up and down?) and slightly faster operation, might make it smoother?

 

very good build, nonetheless!

Very good ! A great entry into the world of Technic.

[Bob De Quatre]

Thanks

If this is your noob effort then I am a fetus.  Good work.

[Jeroen Ottens]

Great model! Not only does it really walk, which is not a mean feat to achieve, but it also has a stunning bodywork

I've tried to build a few walkers over the years and getting a 4-legged walker to walk without toppling over is really an achievement, well done

[Forresto]

When I thought your MOCs couldnt get more incredible, you go and make them walk. Very impressive!

Nice mechanism, and nice build overall.

I agree with Rohan that smaller leg movements might help make things smoother.

I know that you mentioned that you don't have too many Technic parts, but perhaps you could replace the Wedge Belt Wheel/Pulley (in the video version - part 4185) / Liftarm 1 x 2 Thick with Pin Hole and Axle Hole (in the LDD images - part 60483), with this piece if you have some:

Engine Crankshaft - part 2853

This would give you a half stud offset instead of a full stud.

Thanks guys 

It's true that the main problem is the design of the legs. But I placed aesthetics over functionnalities (told you I'm not a Technic builder ), so even if I adjusted the legs, I wanted to keep them thin and long...
