NXT Lego Biped Robot Walker DINO 5B

[TheAc1219]

lol..as if it is on a mission of spying.. like james bond

well done bro

[mcsdaver]

Cool walker.

You should never limit your self.

Legos are great yes, but a servo controller can handle 32 servos.

I wouldn't stop making Lego robots, but you would be amazed at what you can do with servos. Hope to see your next big thing.

Never stop building.

[Marsteintoppen]

@mcsdaver You are right!, but.... A robot made of metal and servos can be made a lot better than a robot made of soft legoparts. But since I am only interested in Lego, I'll stay with that.

[mvshabeer]

Good work. I think you will get better balance if you move the nxt brick to hip area.

I have a doubt. Lego has only 3 servos. It's very limited. An ideal biped robot will have atleast 15 or more servos. then how is it possible to make a biped with this?

[abbrivi8]

dude this is awsome. have you treide moving away from lego and gong for servo?

[Marsteintoppen]

@abbrivi8 No I have not tried to move away from Lego, and I never will. To explore the limits of Lego is what I think is fun.

[DerUnbekannte]

sweet idea!

[calvinthedestroyer]

that's cool

[dhruvdeviah]

can u pls send us building instructions

[Marsteintoppen]

@dhruvdeviah I don't have any instructions, sorry.

[sp4zzpp2]

u can improve speed by weightshift fluently while walking.

[Marsteintoppen]

Yes I know, but that will depend on a major change in design. That's why I startet to build other legdesigns as you can see at my other bipeds. But I have some new ideas, and I hope to develop a Dino 5c, maybe this year, that is able to do what you say without exclude the chicken legs. It won't be easy and I can't promise that I succeed. Chicken legs look great, but are heavy driven and are a bit soft.

[kretzkid98]

You should make the head on top spin like 5 rotations then the oter way matching the legs that you would have o speed up that way it would only have to stop every 5 steps in stead of every one

[dramatickittymovies]

the walker's head is freaking me out dude! y do u have to make the walker lean???

[Marsteintoppen]

This one has to lean, yes. All bipeds has to do weightshifting, this is one of several ways to make that work. 

[monkeyjr58]

@dramatickittymovies im pretty sure its b/c the robot dosent have hips

[MrTimb58]

if you make the feet larger in width and more supports on the leg you wouldn't need the body to shift back and forth therefor a stronger and faster mesh

[Marsteintoppen]

More supports (as you can se in joenagata,s youtube clip of the walker nd1) don't qualify as real walking. It has to be weightshifting involved in the design. I used the "under body support" on my very first biped back in 1993, it was fast, but it wasn't real walking. Check my other bipeds for examples on other types of weightshifting.

[dan70411]

you figured out somthing that most robotic engeneers forget. this bot mooves like a humen... shifting its wieght ... just like us. that bot is more humen than most walkers !

[nealshireman]

that is pretty cool

[Stosh08057]

Nice. Shift the weight over the supporting leg like humans do. . . A walking robot without that strange "big-dog" gate. Nice nice nice. Very creative.

[watchfuleye1000]

This is one of the greatest mindstomes ever! you have a real creative mentality! Do you have your own website? I wanted to build that for my nephew last night but I failed, So can you please post the instructions for this great biped walker and share it with the rest of us? That would be very kind of you. Regards

[Marsteintoppen]

Thanx for nice words. I don't have time for making, ore the knowledge to make good instructions. I will take some pictures of the buildingprosess of my creations and show it on net, so it will be more easy to see how it is put together. But that is not my first priority right now. Maybe you should try to make a biped like my Dino 7? Walks very good, and no programming is needed.

[lightn355]

very fucking tare :X i'm loving it...

[emokid3030]

They should use something like this in a Terminator movie!

[Marsteintoppen]

Yes you are right.

[Thakane]

is that a Microcontroller ?

[Marsteintoppen]

You mean the NXT lego brick?

[DezaOO7]

Can you make instructions?

[Marsteintoppen]

No sorry, don't have time for making instructions.

[NEOxSIGMA]

thats sick

[wrathofmobius]

loved it! it is a large improvement over alpha rex, the bipedal robot lego made. with alpha rex, you had to turn the motors almost all the way off to keep it from falling. great vid!

[Alfaomegabravo]

LOL i like how you fixed the weightshifting to maintain balance. bipedal construction is pretty hard.

[Marsteintoppen]

Thanx:-)

[Buhhhrito]

Very impressive...I take it that it does the whole sideways movement to maintain balance.

[Marsteintoppen]

Thanx, you are right about the sideways movement.

[Feuerwehrler95]

can you send me the building instr.??

[Marsteintoppen]

I don't have any instructions, sorry.

[Marsteintoppen]

No it cannot turn. My DINO X-1 can turn, and my DINO X-2 can turn very vell. Check them out.

[splitter181]

WOW! DUDE! 5/5! I LUV UR VIDEOS :P

[flaviogfernandes]

adorei

[MoTurnPi]

thats the coolest thing i've ever seen

[Marsteintoppen]

Glad you like it. But I think this is a boring design compared with my DINO X-1 and DINO X-2.

[Hacker9876543210]

Cool!

[BulKathos84]

Nice invention. Do you think it´s possible

to apply this way of moving to a robot with

4kilogram weight and 40cm height? :-)

[Marsteintoppen]

Not with a feet design like this, not with Lego. Weight is so important when it comes to lego bipeds. The lego parts bends to much. Hope lego one day will make joints in metal. Maybe the legdesign of my DINO X-2 could make it. But the legs has be strengthen a lot to take 4kilos.

[Marsteintoppen]

No, actually this one I made in less than one day. Mainly because I used my DINO 5 as a reference. The DINO X-1 was a tough build that took time. The X-2 took a little less because I used the experience and the best functions from my earlier models.

[Soviet20]

Good concept the body shifts the weight to the stationary leg while the other one moves. :D

[Marsteintoppen]

Yes it is a good concept. To get real walking you must use weightshifting. I later used the weightshiftingmechanism from DINO 5B on DINO X-1. But the most effective weightshifting walkers I have buildt is my DINO 6B (not yet posted), DINO 7 and DINO X-2. Check them out if you haven't

[axeted]

Swaying like a girl

[Marsteintoppen]

DINO 5B take that as a compliment :-)

[krappies]

BRILLIANT!!

[tigershot843]

cooooooooooooooooooooooooooooo­oooooooooooooooooooooooooooooo­ooooool!

[iRouRoui]

Wah :D Scary, i love it; I wish if he can move faster :o

[clod2692]

great

[toorajii111111111111]

kult og du er norsk :) 5/5 stars!

[KrazyGlueWebcast]

I don't understand what you just said there, man, but I AGREE!

[toorajii111111111111]

I said cool and you are norwegian :) 5/5 stars!

[fopple13]

wow, every step looks really smooth! great job!

[nomasvisto]

Imo you should try to "turn less" the head. It seems to fall at any moment ;)

Great job, anyway.

If you can turn less the head, that "dino" can be a litte bit faster, and secure.

I hope i help you, bye!

[Marsteintoppen]

With this footdesign It has to turn this much, at least. So the design is as good as it was ment to be. The footdesign is heavy driven, so it can`t be any faster. I will not change the 5B.

[pandora88852]

where do you get the motor does it come with the set?

[Marsteintoppen]

This is not a set that you can buy, it's my own design. But most of the parts (like motors and NXT microcomputer) come from the NXT set.

[XNA5000]

that is cool

do you know how you can me the instructions.

[Marsteintoppen]

I have not tried to make any instructions to any of may lego designs yet. But it should be possible to figure it out by looking closly at the videoclip.

[KiffKrooker]

wow. awesome COG mechanism. very cool!

[TheRealManiac123987]

yeah a center of gravity shifting (or COG) robot... (for all you viewers who might not know that).

[sk8man902]

why does the nxt brick keep on switchin sides?

[Marsteintoppen]

The brick switchin sides to keep balance. Human Walk is controlled falling , a very difficult and Complicated Process. To make a lego biped walk, you have to find a way to use the body as a moving counterweight. Think about how you lean your upper body when you are jumping on one foot.

[luuk341]

take that up to nasa

new mars walker

[mallowman12]

thats cool, is the program for it confusing?

[Marsteintoppen]

A little confusing. The program changes throug the walk since the the built in sensor inside the NXT motor not are 100%

But compare to my old RCX version, this one never gets out of sync.

[teddygage]

you should check out the new tilt/axis sensor that works with the regular software, would prob help make programming easier. what set did you get that geared chain drive from?

great engineering btw

[Marsteintoppen]

Thanx fore the tip about the tilt/axis sensor, I will check it out. I got the chain drive from 8417 Mag Wheel Master (1998) and the 8880 Super Car (1994). But you can often find this chain on ilegos on ebay.

[gussdeblod]

awesome, really, the best nxt walker I saw for now.

[goldencricket]

nice design. i love how you shift the weight.

[NJfilms08]

sweet! faved! 5/5!

[CyanideXCloud]

Genius

[tiki820]

COOL-COOL-COOL-COOL

[xyzzzach]

very nice

[bigboss97]

Great job, I love it!
