BUILDING OF AN AUTOMATIC PNEUMATIC LEGO EXAPODE

[TIGERWORRIOR13]

what type of lego is this or is it lego at all

[GanjaSaveTheWorld]

What your cat thinks about this?

[robolegoenthusiast]

@GanjaSaveTheWorld No problems, i built one in legos...

[darkmoon6023]

wow this is incredicle, where did you learn to use to pneumatic systems? i want to build something like this too! thanks for your help

[czomiczek13]

That's why i love lego. People can construct everything with it.

[OktoberSunset]

This is so cool, I wish I had enough lego pneumatic stuff to build something this epic. I'd love to rig something like this up to an RCX and have it roaming about. I used to have a robot ant that searched around for a ball then carried it in it's jaws, but it only had lame unjointed electric powered legs.

[ithinkrobots]

Awesome :)

[mrmotinjo]

They should've made a real, huge pneumatic and/or steam powered crawler just like this one, back in the 19th century. That would've both been awesome, and would have changed the course of technology progression :)

[mickarea]

you are crazy intelligent!

[SolarAlliance]

*imagining this thing minstorms-controlled*

[SuperLeader96]

well done man, i tried to make almost like that, but finally i got huge scorpion)))

[anirunescape]

Too many wires

[weejass]

Incredible design! I once thought about doing a build like this but after 2 days of brainstorming I imagined it to be a mess of rubbery hose, lack of airpressure and more bricklink packages than money could buy. I Applaud you for your perseverance through those hardships! It really looks great!

[PolakboyHL]

nice!!!!!

[ladams00]

Nice, time for some MAC solenoid valves and a micro controller :)

[lexion510]

Simply brilliant! You deserve a medal or something :)

[spartan7126]

where do you get piston things i really need a few oh and the compressor

[robolegoenthusiast]

@spartan7126 all parts are available on ebay

[TommyTMOD]

@robolegoenthusiast on ebay? thanx, i found it, but now i am wondering where do you get money for it ?? :D

[yzorg]

@spartan7126

these are official lego parts...

[ILoveMixery]

24 cylinders, right?

brilliant work, well done! i wonder how fast it can go if you increase the pressure... but it will sure be a lot of searching if some of the pipes disrupt :D

[Welcome7oHell]

To slow

[WrathConstantine]

@Welcome7oHell So is the troll who doesn't appreciate the complexity of this build nor think of anything nice to say.

Great work, Robo!

[skullrdw]

Hi, how did you manage to get enough air pressure to make the EXAPODE walk ?

[robolegoenthusiast]

@skullrdw Hi, With a 100L compressor.

[jrw6137]

öm anything else to say than awesome yep make an motor and a gear controll the switches and add a small comp and it will automatically work without switching arround^^

[jazz0613]

my mom would of been like"KILL IT!!!!!"

[robolegoenthusiast]

@jazz0613 Why? She don't like ants or she don't like legos??

[MegaBeatbreaker]

nice !!!!!!!!!!!!

[HoneyIShrunkTheKids2]

you have the makings of a robot!

[lazygsxr]

That just looks awesome hats off to u for making that and u must have a bunch load of cylinders and piping

[AKSoapy29]

O_O Wow. Have you ever considered signing him up for Roblox? It's like virtual legos, and you can build your own game for yourself and others to play! I play it and I think it's fun. Plus it's free to.

[robolegoenthusiast]

@AKSoapy29 We tried LDD but we prefer having real assemblies to be finalized. However thank's for advice!

[ShokaLion]

Is it actually clear of the ground when it walks or does it drag itself? Either way excellent build. I love purely mechanical stuff like this. Excellent work.

[robolegoenthusiast]

@ShokaLion Legos are only toys and this very heavy robot is supported by visible wheels in 1'59" when the head is up. Thank's for comments.

[Phillip3223]

was it verry expensiv do build this robot?

[robolegoenthusiast]

@Phillip3223 About 200 euros on E BAY

[AKSoapy29]

You could use an Arduino and solenoids.

[robolegoenthusiast]

@AKSoapy29 No because Arduino and solenoids arn't lego parts

[AKSoapy29]

@robolegoenthusiast We'll, it's just an idea. You wouldn't have as many parts as you do in the video, and it would be less complicated. But nice robot :D

[robolegoenthusiast]

@AKSoapy29 These assemblies are challenges which i throw to my 11 years old son, he plays to realize it only with lego parts! However thank's for your comments!

[kleinesmaenchen]

you realy need to get an nxt on it

[robolegoenthusiast]

@kleinesmaenchen No! it's too easy with an NXT !

[kleinesmaenchen]

@robolegoenthusiast why ? i would just mechanikaly control the levers.

[Presentfactory]

Pretty simple, as in how the legs move, but acquiring all thoes parts is the hard part.

[googiefive]

looks like somebody poured noodles all over the crawler

but a sick way to connect up newmatics... or however you spll that word

[eoneon667]

It is cool  but kinda useless.

[nicoslego]

nice nice nice!!!

[upgradeengineer]

NICE, reminds me of the movie "steam boy"

[upgradeengineer]

NICE, reminds me of the movie of "steam boy"

[robolegoenthusiast]

@Dudeofmanyhobbies Everything is bought on Ebay

[MiniNinja224]

Can I buy that

[robolegoenthusiast]

@MiniNinja224 Each model is removed to build the next one !

[HavazikFerric]

The sound of it, just amazing!

[sertin890]

sick



[preedalist]

Cool Creation!!!

[MuchiBuri1]

I guess...a flyswatter won't be enough then

[thepaingainer]

Incredible!!!!! something like in "Wild wild west" respect for genius

[revilo314]

Pfft. I built that in Minecraft.



[013dirtdiver]

THE GUY NEEDS A HAIRCUT :D nice project!

[MyopicM2C1]

I realise during the phase where 3 legs are lifted in the air and swung forward, why are the 3 supporting legs not shifted backward at the same time? Potentially saves time and complexity of the pneumatic circuitry

Nevertheless, still awesome to see Lego Pneumatic creations, need more MOCs of those!

[robolegoenthusiast]

@MyopicM2C1 Hello! It takes a large volume of air at 32.6 psi to operate pneumatic actuators that move the legs and the general supply pipe is not big enough to power everything at the same time! We must increase the presure but the pipes don't support it. Moreover, this assemby was a test to see how enchaining movements one after another with position sensors. Thank you for your interest and comments.

[MyopicM2C1]

@robolegoenthusiast I suspect that plenty of pressure is lost via the piping; there are plenty of excess cable length! Then again for its size its understandable it needs high pressure to operate..

Are the legs AND-gated together? That is, if I were to block one of the legs from finishing its cycle, will the circuit still continue without letting the leg finish its movement?

[robolegoenthusiast]

@MyopicM2C1 The movements are controlled by position sensors attached to the central pair of legs. If the movement of these sensors is blocked, the following movements are stopped. This assembly is nothing else that an automaton.

[BASS0090]

It would be scary to hear that Psihh-psuuh-psut- sound suddenly in the dark :D

[Hogaboga101]

u need cabel ties.. :P

[iownudie108]

CAN U SPEED IT UP?

[robolegoenthusiast]

@iownudie108 no, it's too heavy

[robolegoenthusiast]

The 100 L compressor is in the garage and the air arrives by the pneumatic hose that you see at 4'00'' behind the robot

[williboooooy]

@robolegoenthusiast thnx

[subgerocallidus]

@robolegoenthusiast Could you create a pumping system that worked with a lego motor with batteries. It would likely be inefficient, but would remove the need for external air.

[williboooooy]

is there a compressor in there?

[williboooooy]

NICE NICE NICE

[sabladask]

cool!!!!, and a good build!

[loppan26]

Awesome



[Revosgonewild]

This is by far the most impressive and well made lego i have ever seen, great work

[Chapichap0]

balaise mec ! ça tue ton truc. comment t'as rendu le tout automatic? t'as un distributeur derrière?

[robolegoenthusiast]

L'automatisation des mouvements se fait avec 4 switchs commandés par 4 vérins dont la position dépend du mouvement précédent et ainsi de suite. Le cycle se répéte à l'identique tant qu'il y a de l'air. voir à 3' 53" au 1er plan les 4 vérins couplés aux switchs.

[animatorSimen]

realy cool and a lot hard work?!!, its like a robot-insect i a future-movie.

even more impressing if you had combined the power functions and made some air compressors!!!

[theguymjp]

Impressive!

[vartaize]

how much pipes are in there?

[robolegoenthusiast]

6 x 6 legs + 4 in the head + 16 for the automatic system = 56 pipes.

thank you
