Syringe Actuated Mechanical Arm

[frank26ification]

very well,my friend,i like your project

[kill600]

use water in syringe do avoid compression delay

[saadrkx]

gr8 design..i will try to build it...thankxx for the video......

[kdc43]

You build something that is slow, cumbersome and you use TWO hands to do something that can be done quickly and easily with ONE hand. I guess that's progress!!!

All joking aside that is still educational.

[Nate111469]

how do you get your grabber to work?

[bhujelshovit11]

nice

[124gotcha]

i like it but it

[rage3012]

can u please give exact mesurements of the wood or a diagram??/

[SuperMalayam]

nice one never seen such hydralics robot arm

[ZedeMzee]

Hey can u please please give me the instructions and measurements for how u made this, i need it urgently for a science, anybody who could help , please reply.

[no1841]

can you please explain more detail about the claw

[TheMrMechanic]

that is really cool!!!

[LscAndrew]

Interesting! Good Job!

[SUNIL12527]

Hello sir i want to make it can u help me how to make it plz my address sunil.dinday@gmail.com

[DragonXflyer]

Very Cool! I love innovative creations like this.

[YeCkX]

How is it done?

[TheJefedesapuka]

so fucking coool

[JOHNNYCOMEKILLU]

Now thats just strait bad ass

[holt0025]

hi i have the same schhol project but we can only use air in the syringes which makes it much harder so ill have to use a counterbalance, but i wanted to ask u exactly how to picking tool works cos im not understanding

[AtomBom333]

lol



[Leonardo93255]

LOL FANTÁSTIC!!!!

[xxCJ32xx]

real cool.i looked this up because were doin it in tech-ed

[hooba42]

the hand working is super cool man.....keep up

[matloc12345]

what size ciringe did u use

[013dirtdiver]

nice work, I first saw the idea in the mythbusters

[Foxrope2]

that is really cool!!!

[TheRastamon42]

dang, when i watched this, i thought it was a kit! :P i made one, too, but its nowhere near as nice as yours... :\

[blackscimitar]

so nice! i bet u got an A for this model ;-)

[cflhorselover]

can you tell me how to use the gripper? I need to make one and i cant find anything on the internet to make one

[mysdak]

Borrowed some elements of your design.

[heyitsfreddy]

Wow, thats pretty cool! haha, good job.

[olrac120]

dude!!! can u send me some pictures of your mechanical arm........all views.......because i'm going to make one....

[crazydude40405]

can you make a tutorial pleawse

[ShugoCharaDokiHeart]

It's a really really good arm! Why did you put the elastics on the gripper though?

[freeScribblenauts]

where do you get the Hydraulic/ pumps from

[eBiology]

Very nice, I want to use air instead of water... but air is compressible and water is not.

[blqkvo]

CLEVER! CLEVER! CLEVER! I`ve had the same idea for a while, but I always end up using the syringes for the wrong thing...

[xJASMiiNE]

can you take a picture showing how you attached the syringe to make the claw close and open? i need help on that part!! :(

[Runningman3200]

how does it turn?

[sethbramwell]

very nice design. I did something similar to this on the fly for a Master's degree robotics class. I might suggest replacing the rubber band on the gripper with an extension spring/ It's less prone to wear.

[Jefenry]

@sethbramwell A spring with the right tension would have been the best idea. I basically ran out of time making this one and just bought a big bag of various rubber bands and tried them until I found one that worked.

[TheChewyandnene]

@Jefenry How long did it take you to build this? Please respond!

[Jefenry]

@TheChewyandnene I'm not sure, but I think we had around 3 weeks to work on it, so maybe 10-15 hours? Building it didn't take too long, but fine tuning it did.

[124gotcha]

@Jefenry fucking hate you i failed this project and ur gey

[SPFGaming]

ill give you twenty bucks for it!!!!!!11

[jeanrazac]

cool is it pneumatic or hydraulic? 

[Jefenry]

@jeanrazac It's hydraulic. The syringes and tubing are full of water, although it's hard to get all the air out of the lines. Pneumatic alone doesn't work very well at all.

[MarshFacev2]

@Jefenry

Do you ever have problems with it leaking?

[Jefenry]

@MarshFacev2 There's no noticeable leak when I'm using it, but over a period of weeks/months the water disappears and I get air in the lines. I'm not sure if it evaporates or very slowly leaks out, but I do need to top off the water every now and then.

[vinaymechrox]

good buddy

[pivot675]

wery good I like the look of it and the wood too.

[bigdog0224]

awesome

[GeneralAnimator]

thats the weirdest thing ive seen today O__O great idea !

[smilinrk2003]

Very nicely done!

[pierce51700]

cool

[spiykar99]

osm u r best cuz no i gives detail about the gripper i wish u also give some detail about how does the arm turn

[jjesl]

what i see is that you are using different piston diameter, having then a mechanical advantage increasing the output force. congratulations dude!

[movielova96]

wow!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!1

[LilMissz96]

Can u plz send me the instructions to make this ?? please i would reaalllyyy lovee it :) thankss

[Jefenry]

@LilMissz96 Sorry, I don't have any instructions. It's my own design and I just built it as I went along.

[DeadBodyOutline]

Neat project

[KagamineLenX3]

mi grade 8 class has 2 do this as well and its due in lik 2 days...anyways, we hav 2 pick up a foam whale w/ a 250 gram weight in it, so i kinda wanna use a claw but this claw wont b able 2 grab the whale n ther isn't much time yet...any idea of a claw tht can grab a whale or how 2 work a net? (the whale is not flexible btw and is long)

[mandinator96]

Hey this is brilliant. we are 8th graders and we have this project to make a mechanical arm. do you have simple instructions on how to make this?? that would be so awesome. Also, a list of materials needed. thanks!

[monkeygirl4554]

@mandinator96 is a girl in my class as well

[monkeygirl4554]

Hi! My eigth grade class is trying to make a mechanical arm that can pick up a pencil. We love your arm but when we went to your website we couldnt quite gather enough information to build it! If you can help is it would be fantastic! Get back to me ASAP! thanks

[Jefenry]

Sorry, I didn't have any plans, I just built it as I went.

[water353600]

beautiful

[charmedtwilight]

i have a few questions...did u buy the wood or did you cut it urself? and how did you make the arm rotate?

[Jefenry]

I added a link in the info box to a picture showing how the arm rotates.

[megadan01]

Brilliant!

[legendofzeldafreak2]

YOUR A GENUIS!!!!! thank you SOOO much for posting this. It's really helping me not fail Tech Ed!!!

[tan0523]

thank you :) great model!

[redpanthers724]

where did you buy the syrenges ?

[jesusfreakpeat]

how long did it take you to build that?

we have to build that in grade 8 science

what materials did u use

we have to make that too

[gamerpro4268]

how do you make the arm rotate?

[Jefenry]

One of the syringe plungers has a piece of coat hanger wire attached to it that pushes a knob on the circular base.

[ILuvYaoiRawr]

@Jefenry I still don't understand the rotation thing D': a knob as in the wire is attached to the knob and the syringe thingy is pushing it? and cud this also be used with gears or sumthin instead?

[Jefenry]

I added a link in the info box to a picture showing how the arm rotates.

[KZKZKZ9]

ur a genius...
