Giant Robot Project: Part 35 I dunno....

[LithiumLogica]

"Good enough!" <-- Love it.

[TheRunningPuzzle]

so, where do you keep the iron man suit?

[sylleman]

Okay this stupid comment thing bashed my awesome explanation. Hope you understand me, i'm swedish so i'm doing my best :-)

Anyway. The legs are 2 straight bars, attached to the ladder. the springs and the "Pull thingy" aren't they putting a lot of strain on the lower bar?

Putting a bar or something in the middle of the 2 bars connected to the ladderleg would make some of the pressure move up to the bar above aswell? I might be wrong tho, im on some skinny ice here really, to me it's logic tho.

[sylleman]

Not that i know anything in particular regarding building stuff, but my logical sense tells me, shouldn't it be a benefit to put like a straight bar/pipe at the middle of each leg?

Something like that? Since the springs are putting tension on the lower bar, chances are it will bend? And welding a small aluminum pipe, would that make it sort of a fail safe for the legs to bend? I think you already considered that tho

[dirtTdude]

but what does the up and down expandogazmic gizmo on top do?

[JMEMantzel]

err... they uhh.... make it much more efficient.

[RoboticAlchomist]

plese respond,...

why were u playing heavan in te background by like 3 diffrent people over andover,...?

[JMEMantzel]

uhh... I have no good answer. I wasn't really paying attention. I guess I have those songs in my ipod, and they were probably playing in alphabetical order.

[djdolber]

Hi! Just discovered your videos the other day, your determination is very inspiring! i will keep following your progress and future projects, cheers!

[JMEMantzel]

thanks! I'm doin my best. :-)

[user7450]

why don't you use that chain lifting thingy to move the robot around? you could easily make a little mobile crane.

[JMEMantzel]

Ya... there are about a million things I could easily do.... and would like to. Unfortunately there's only one of me. ....and if I did tham all it would take several thousand years. :-P

[blenderit]

for curving, "double-t" beams are double as strng as round ones, for torsion the "double t" is the weakest, (10 times weaker thn round) you could take a square one - its 20% stronger then round shape for curving and only 10% weaker for torsion

[JMEMantzel]

mmmm... I love box tube. (square) (...or rectangle)

[LudicrousTachyon]

I'm not sure and I can't find anything about it online, but I think I-beams may be stronger and more durable than tubes. Then again where are you gonna get I-beams.

[JMEMantzel]

I can get I-beams... or make 'em. The ladder sides are basically I-beams.

They're not strong enough, though. ....easy to twist.

[Brute4rce]

what thickness can your welder weld aluminum?

[JMEMantzel]

reliably 1/8'' ...but... I've been cheating.

[hakachukai]

Nice work! You might have already thought of this, but you might want to consider side to side flextion of the legs when the robot is walking forward. If the leg flexes too much, the cables will probably pop off the escentric pulleys. Maybe you can make some cable guides... or find a way to limit how much the legs can flex. If things are strong enough, you might be able to eliminate the cables all together.

Anyway... hope that is more helpful than annoying.

[JMEMantzel]

Well... I did think of that, believe it or not. ....and the legs don't flex much at all. It operates without the cables and springs, but it can handle more weight with them...

[hakachukai]

Cool beans! Hopefully it will notbe an issue then.

[Poldax]

Keep The Beard, its great.

[futsalfred2]

You look cooler with the beard on man

[Karpens16]

it isn't so hard to see, we're in heaven.

[edjorg]

awesome techno!

[anmoyunos]

It's the spirit, not the birthplace, that I care about.

[1968charger666]

Have the robot help you finish the bannanna building! :)

Ach, I can't spell bannanna and apparently neither can spell checker.

Keep up the good work!

[awsutherland]

Someone aught to give you a Haas CNC machine, some computer cad software, and a few tons of aluminum to see what the heck you come up with.

[paperjack93]

Woah your beard grows very slowly

[AMonteverdi]

dj sammy we are in heaven ...tuutiituuutitititu ..jaja clasic electro trance jeje for me jeje

btw YOU ARE ALSO AMERICAN ...im also american ...AMERICA IS A CONTINENT

[tomasahlin]

Isn't America 2 continents? South- and North- ??

[AMonteverdi]

nop... its just America

-america is a continent no a country...-

[captcaveman4201]

great point! it validates what i said even more.

[Noxol101]

the country amarica?...no

[tomasahlin]

I ment north america is one continent (and has about 2 - 3 countries depending if you count greenland) and south america is another continent and that one has lots of countries. I've read that america sometimes are refered to as a dubble continent.

[tomasahlin]

oups... of cource central america belong to the north- half of america, so there's probably are way more then 3 countries in north america.

[captcaveman4201]

haha he claims he is a Canadian like he is taking the highground.. i hate to break it to you jamie.. but you've been naturalized.. you live in VT and work at shaws. that means that you are an american now..just like pablo from mexico

[J0nteH]

I'm from sweden and in my sight of view, Canadians like the forest/hunting and such. While Americans sit on Mc Donalds and eat hamburgers all day. That tells me jamie is Canadian!

[DeoMachina]

Jaimie was totally in my dream last night. People were building this really tall/long wall and he was slotting stone blocks into place (for some reason the wall wasn't getting built row by row)

What does this mean? I spend too much time on Youtube.

[futsalfred2]

Yeah I have dreams about Jaimie too :)

[Nekiu]

Getting a few Text messages there are we? =P

[MattMacLean1991]

Third! Everyone tries to be first, so why not be unique? :)

[Realizalize]

did you try to be 3rd?

well, thats the d.ferenc.

[jtfyou]

Technically, you're 4th.

[blogs454]

Hey,

can you explain the 'rabbit ear' (6:30) mechanism sticking out of the top please.

I understand how the legs work from your little spider robot.... but I don't understand the 'rabbit ear' part. I'm guessing it drives the legs... but how?

Thanks

Looking good!! Can't wait until this thing walks :-D

[Flaringo]

woohoo :D
