Lego Technic Syncro Drive Automatic

[appleintosh]

Somehow this reminds me of one of those really old mechanical computers from the 1940's that used gears and gyroscopes to do stuff instead of silicon chips and stuff

[PhilArbalest]

dude, you should start playing garrys mod!! :D

[burf2000]

Hey there, I really fancy building one of these, if I got stuck would you be up for helping me? 

[xyzzzach]

@burf2000 surely, for detailed building instructions check out a link on a video by aeh5040. His syncro drive is cool too. If you run into problems let me know, I'll do what I can!

[boboexe]

it's cool :D

[Thedragon504]

very nice



[ilCepu]

very good idea!

[NoFearDaveIsHere]

Wow, great idea!

[wackyLegends]

IF they make Lego parts more strong it can be used to build larger and more complex robots.. ...

[pillowcase1]

there is something about this design - its so awesome.

[RudyVal1000]

sweet!!!!!!



[F3udF1st]

There's no way you invented that yourself... That's it, I quit.

[MrThemizzshaun]

how long did that take you??????

[xyzzzach]

@MrThemizzshaun

about a week solid

[MrThemizzshaun]

@xyzzzach wow id take about 2-4 weeks thats amazing!!!

[xyzzzach]

@MrThemizzshaun

thanks a lot, check out my syncro drive mini...!

[MrThemizzshaun]

@xyzzzach wow thats even smaller awsome i love your vid's!

[Dudeofmanyhobbies]

wow you have invented mechanical sensing! how many differentials did you use?

[xyzzzach]

@Dudeofmanyhobbies

there is one in the middle.

[pokercees]

This machine, it's beautiful! you don't need a NXT set, I would say this machine got a brain of it's own compared to digital robots. I got a NXT set, but even with 3 electro motors I found it hard to build a properly functioning robot.

[bruge10]

It just want to go home!!

[Golfi1812]

Wow super! Super!respect

[xyzzzach]

it came from the hailfire droid set 4481, you can buy the "ring gear" seperate at bricklink.

[jeremu5]

where do you get those large gears? i mean those really large, those that is around it.

[ProgressiveForest]

THAT IS INGENIOUS

[bruno85555]

amazing!!!!!

[Madmonkeythegreat]

Oh the infinite uses of the hail fire droid wheels.

[DaanCopal]

Just brilliant....... i woudnt have thought of this without using an rcx or nxt....amazing, genius.. best technic creation i have ever seen, and i have seen many.

[xyzzzach]

@DaanCopal

thank you very much!

[noudgoertz]

you must put an pencil on it!

[CaptJiggles]

Am I mistaken of is a collision detected by a stall on the motor turning the large wheel? (that would be genius)

[xyzzzach]

@CaptJiggles

the ring gear on the perimeter is on the same differential as the turning mechanism of the wheels. Power just follows the path of least resistance. When the gear gets bogged down (hits a wall) power then transfers to turning. The motor itself doesnt stall or get effected.

[CaptJiggles]

@xyzzzach

Thats even more genius! Do you have building instructions?

[travb81]

Bloody awesome, wish I had some of your creativity.

[Everfalling]

how clever.

[Buemmo]

So i guess its all in all working like a differential. If one is blocked the other one way is blocked the power takes the other one. Great work!!!

[Fastbikkel]

Nice stuff, interesting to see how that thing works.

[Hoser1358]

OMG It's like a lego Roomba (Robot Vacuum) XD

except... it doesnt clean but it's still quite amazing

[jozet77]

thumbs up just cuse i dont know what it is...

[SoilentGr33n]

Now THAT'S a cool contraption. You could extrapolate on it and make an automatic transmission

[PunkForLife55]

very nice. most people think legos are kid toys. but really there almost not

[Zblj1987]

You used a differntial to 'feel'? Great job, really unique!

[aeh5040]

Congratulations on a truly marvellous invention! I made my own version of it (see the video response). I also have two other designs for a purely mechanical obstacle-avoiding robot (see my channel).

[linmix]

Really nice one. Had seen it before, but was reminded of it by aeh5040's adaptation. I like the low speed in this one but I'm curious to see if the other one *will* turn against a shoebox...

[PhiloYT]

An awesome idea I discovered through aeh5040 adaptation. Congratulations!

[SgtDenny11]

Dude that is some serious brain power you got great invention. I'm planning to be an engineer. : )

[xyzzzach]

thank you, i wanted to be an engineer too years ago

[heribertor88]

So do walls have a resistance equal to or greater than your finger? I don't think it will work well on walls.

[xyzzzach]

it's the same, if I put it in a shoe box it will bounce around forever

[heribertor88]

@xyzzzach lol cool man! Then it's a win!

[ShokaLion]

@heribertor88 I'd have thought that it'd just continue forward until the resistance against the large wheel is enough to cause it to turn.

[matejz101]

AWESOME!!!!!!

[bigdestroyingrobot]

awesome

[theunforgiven1997]

are you a engineer or something,anyway really nice work!!

[xyzzzach]

I am an aircraft mechanic, thanks!

[MrOzzi96]

Are you an Aircraft mechanic?? COOL!!!

[webdoggboy]

what is the ring from?

[Spanksh]

It's from the Lego Technic Hailfire Droid^^

[watchfuleye1000]

Amazing !

[demondman50]

i dont have to say this but...your very very skilled in enginering! bravo man, GL with the masters from MIT

[roboman0222]

I am amazed. Wow.

[jt1073392]

thats so freakin cool but on that crapy washing machine lol

[LazzuroVolpe]

lol thats not a washing machine, thats an stovetop/oven!!! why else would there be spatulas and spoons there, and the burners were to the right of the stove

[trackspike64]

ok where do u get the big gears

[Hikar755]

Wow. I'm speechless.

[philipooos]

Excellent!

[miguelitoleal]

yo quiero esa rueda donde la consiguo??

[maarce1990]

Very nice but ... why on a washing-machine ?XD

[amj441]

What would be better is if you made it a vacuum.

[AustinOO3]

Genius

Keep up the good work

[L3G0nerd]

interesting

[MorkaGraven]

Nice

[ZentaOlbaid]

Excellent work! Awesome work on the mechanical constructions.

[MyopicM2C1]

The most elegant Lego implementation of a differential collision detector I've ever seen. Genius!

Generally the typical mechanical collision detectors I've seen puts the differential between the drive wheels and the turning system. I'm assuming that the drive wheels which moves the synchro are constantly powered, while the differential is only between the huge ring gear and the turning system?

[xyzzzach]

Yes!! Nice to hear from another gearhead who understands the concept. Also check out my tri-wheel climber, it has 3 differentials all working together.

[Zblj1987]

Really smart! 5/5

[spartonne]

Sweet, good work! How did you think of that? I assume you want to be an engineer? You should...

[Mattshewster]

this is amazing... it is so under exploited!

[09204418448]

Einstein of the day

[olive1913]

OMG you are genius, never ever thought of an idea to make that via mechanics possible

[xyzzzach]

thanks!

[jarradhewett]

OMG

WTF

[moldo2]

agree

[solitajre222]

...so if it runs in to a wall it will just go the other way!...

awesome!

[blamtam]

impossible! unbealevabal sweet must have taken weeks to build!

[Zut50]

Incredible.

[DarkedSshadow]

realy nice!

[TolaniO]

Yo this is Genius!

[Dirtboy101]

WOW! that looks like one of those vacuum things that go around the house and vacuum for you! wow!

[pielover48]

wow, that is a cool washing machine, also cool lego thing

[theyoungster2]

omg, you are a complete mastermind. 5/5!

[apocalipsisnow666]

its very impresionat

una pregunta donde consigo elmaterial para construirli y como se hacer???

[rocketman468]

that is one om the most cleaver things i have ever seen, nice job man can you make like a simpler ldd model and send me? i wanna make it smaller

[TINKONPOOPKORNER]

nice turns direction when it hit something!

[ghostinside]

Yeah, I gotta agree that is one of the most brilliant designs I've ever seen. Good job!

[livebionicle]

wow! please do a how2

[heldan898]

It realy makes sense! Quite amazing.

[greenykevin]

omg that is the most ingenous design on earth omg 5/5 mzing make instructions

[TIM1TULIAG]

very very cool

[GrossProphetMargin]

Really nice work. I love things that only need one motor.

[truespiritshaz]

thats cos you only got one motor. you poor poverty stricken freak!

[raziel899]

AND THAT, GOING TO MARS. SOME DAY.

[pogodrummer]

excuse me can i buy the external gear wheel separately?

[xyzzzach]

They're for sale at bricklink, kind of expensive though

[computermedic64]

lego hailfire droid set, the old one

[Anarchemitis]

So if the exterior ring encounters resistance, the legs rotate?

[xyzzzach]

exactly!

[tiki820]

Brutal.Cool

[owendicko]

definately patent it... before someone steals your idea (assuming it is your idea)

[zeleftikam]

This is amazing! I can't believe it works so well purely mechanically. Can you think of a commercial application of this design?

[xyzzzach]

I should patent it!

Maybe in a kids toy or something....

[Chachachadaa]

vacuum cleaner!

[omega778]

severo!

[squeekzilla]

What is the outer perimiter wheel? Where can I find one?

[xyzzzach]

it came from the hailfire droid set 4481

great ring gear

[gonzalosarlinga]

Te felicito!

[xyzzzach]

thanks everyone for the comments!

[c0pi]

Beautiful!

[zagaberoo]

genius!

[james2bond]

nice job

[commanderfreek]

wtf

[wurft]

cool!

[mindstormers]

dude... you are genius

[jepordy3]

has anyone ever made a monowheel out of legos?

this one is cool...so whenever it hits a wall it turns around?

[AuKiiraa]

wow thats smart

[quiqui1396]

thats a great concept! check out my robots

[Lynx86]

wow! i mean... just wow!! I'm speachless. Amazing dude, congrats.

[nitrousoxijk]

ok left right what about forward and back?

[xyzzzach]

Even if it hits something at an angle it will still turn away from it. If you put it in a box it will bounce off all walls forever.

[MonokuroBooHokKan]

THATS AWESOME!

[IPLAYSCRABBLE]

thats real engineering dumbass, without this you wouldnt have a computer or a car. these "nerds" are the center of technology so unless you prefer being a caveman shut your trap.

[malex102]

ur probally a nerd ur self ass wipe

[IPLAYSCRABBLE]

your probably a low-life junkie, who gets a kick out of insulting peoples interests. If I got the junkie wrong then whatevs. But I didn't get the low-life part wrong thats for sure >.>

[malex102]

wat the fuck

[sulomo]

ok now THAT is a nice piece of engineering, respect!

If i understand correctly: when the outer ring is stopped, the 4 wheel modules underneath turn on they can move forward freely again?

Im impressed.

(do you have some instructions on how to build it somewhere?)

[salvix001]

Cool idea! Please continue your life without a girlfriend as your MOCs are quite interesting! :-P
