8 hours

Description: 

well, it's my first manipulator. ist's nothing special, but it's better than everything i did with this metal contruction box i have. it would be great, when there is someone who wants to help me, so i can control it from my pc, but you have to know ,that i'm totally new in this stuff(but i work hard to improve myself). i work on a new project wich shoud be ready after some months, but i'll probably make a video before that. so, enjoy!

Very well done...Now in the

Very well done...

Now in the spirit of drumming machines - it just needs a drumstick and something to rap on.  If its going to keep up with the sound track you may have to up the voltage significantly :) 


considering you did so well with the video - maybe you could make it look like its fast by removing every other frame,

keep up the great work

Very Cool!

Don't be rediculous, what a wonderful device! Very well done! What code/ microcontroler did you use?

well, that was my point

well, that was my point naming it "easy-made".. there is no controller, no code, not a single resistor, etc. the manipulator is controlable only with a "joystick" i've created. 4 servos - 5 buttons(the best i could make without any electronics knowledge). but it's comming more and i will need help for that(soon)!


Still Impressive

You don't give yourself enough credit. You might want to make this into a tutorial. I might want to try building one of these.
little_spiro's picture

:) i might, you might (:

10x! i'm glad you liked it! but.. it's too late for a tutorial... i needed some of the parts for experimenting and the robo-hand is half apart. the good news is that, its not that hard to make something like this. there are only two tricky parts - motors 1 and 4. i can help you telling what is NOT going to work, in case you want to build it. the rest can be build the way you like it. i can send you hi-res pics on your mail, if you want to, but a whole tutorial...
10x again!

Tutorial

You can't piece together a guide of some sort? I'd love to make one of these. Brennon
little_spiro's picture

heh

:) i can, but i will not... it's simply TOO much work. why don't you start, as i told you and i'll help you with everything i can. i don't really understand what you expecting from me - a detailed plan what comes first, what second, with pictures and videos?!? :) i will need weeks to make this... as i allready told - i have hi-res pictures, where u can see allmost every part. i never used tutorials building legos or metal kits like this and i don't see the point making something exactly the same like someone else did.. don't be angry, but there is NO WAY loosing 2 weeks for a tutorial. i will make pictures for every step in my new project, but i won't build THIS one more time, only because u wanna know which nut comes first.
i'd love to help you make one of these. :)

Way cool!  Love the

Way cool!  Love the construction!

Are those regular servos or the ones that came with the construction kit?

little_spiro's picture

no servos in the kit included

i bought the EITECH C60 and EITECH 65 kits from ebay. the servos are the cheeper in germany - MODELCRAFT RS-2(~3€). i pulled out the whole electronic out, so that it runs continuously in both directions. that's it! tha whole thing costs ~18€(without wires, because i have a lot of them and i didn't have to buy new)

;)

Can you post some more

Can you post some more pictures? This is pretty cool!
little_spiro's picture

uhm?

there are pictures already... i have the same and a bit more in hi-res, but the forum didn't allow pictures over 500x500. you can watch the video in youtube in hi-res too..

Huh?

I post 1mil X 1mil all the time!

erh - well it is scaled

erh - well it is scaled down, of course. But you can attach them as files if you want bigger ones. And I also recomend having them in picasa, flickr etc where they specialize in large images / thumnails etc.
little_spiro's picture

yep,

but the f*cking picasa don't play GIFs :((( i have an album though - http://picasaweb.google.com/little.spiro/TECH
fritsl's picture

Huh? Oh - Animated gifs?

Huh? Oh - Animated gifs? That was 1999, my friend! Today = no more animated gifs!

However - if you do have your pictures there;

A) in "more information" why not enter the URL to the album there? (edit your bot)

B) When inserting images - why not just copy the URL (right-click image in Picasa, get address) - and insert them by pasting that URL here on LMR - much simpler :)

Animated GIFs RULE!

Dude, not everyone has the time to keep up with change. Two kids and a mortgage would show you what life is. Now, if you were to switch on animated GIFs, you would be able to see the FRONT of my avatar, not just the back.

1999 was a great year for the starcraft players too, but that do not means i can't play any more. the year is 1987, though(and an URL, of course - http://en.wikipedia.org/wiki/Gif). so give me an advice and tell me how to put a hi-res animation in a forum without using GIF. i mean something like this here - http://robotics-bg.com/forum/viewtopic.php?p=3298#3298

A)because i'm not sure, that i'll stay here for a long time

B) because i don't like poor presentations

We don't see enough Meccano around here.

Let's work on an RS-232 motor controller.

Let's work on an RS-232 motor controller. !!!!!!!!!!!!!!

Uhuuu! well, that's what i was waiting for! shoud i buy new servos WITH electronics, or it's ok without too..?
BaseOverApex's picture

Servos

Well, if it were me, I would not have ripped out ALL the electrics. Buy a couple more and either:

 

1) just rip out the potentiometer and solder in a pair of identical resistors in its place as a potential divider

or

2) leave the pot in, but saw off the twiddly bit so it doesn't contact with the output shaft. Twiddle it so it's in the middle.


THEN, all you have to do is write a program to output a square wave pulse. one pulse every 18.5ms. The pulse length should be between about 500us and 1500us and the length is directly proportional to the motor speed. Values below 1000us will drive the motor one way and above 1000 will drive it the other way with 1000us being "off".

Piece of cake.

Keep your eyes open and I think you'll soon see a bunch of generic robot "modules" being develope, oe of which is likely to be an RS-232 servo controller.

cool!

I have somewhere to lay such a designer :) will try to assemble such a robot :) Mp3

:)

it's easy and low-cost, so do it. i'm sure you can make some improvements. the hand(how is the english word - gripper?) for example. it's too slow and unsteady. the base isn't the best too. but it's probably the best for the price. try it. it's fun for couple of hours ;p

Not LAME!

Dude that is soo NOT lame!! BTW - what is the tune inthe video? I know somone who would be extremely irritated by it.

new control joystick

hi guys! i wanted to make a new control box for my robot, but i'm done only with the half of it. that's for the fingers(up/down) and the base(left/right). any ideas how to make the second part? i need 2 up/down sticks for motor "2" and motor "3"..
