Hallo everybody, this is my first LMR entry (not the first robot I build)

I made this delta robot over the weekend.

About two week ago i saw a video of an industrial delta robot and i was intrigued by the simplicity of the principle but the complexity of the movements it could make.
So i thought, I'm gonna make one.

So i bought three servos some ball joints and some aluminum strip.
The metal base plate I had laying around. Just as some some nuts and bolts.
I used an arduino i took out of another robot i build (i will post that one here two)

I programmed the arduino so it reads serial data, and I made a mouse interface that sends the serial data.

And in actually turned out to be as simple as I thought it to be.

But now I have a delta bot I should do something with it.
I'm not quite sure what.
I had the idea to make more of these and use them as lags for a two, four or six legged robot.
It will work well I think, but it's a bit expansive to make six of these.

Here`s a suggestion, stick a marker on it and have it draw PCB traces for etching :)

I got a pack of tamiya ball joints last week to do this but they don`t have the same range of motion as yours. From eyeballing it I would guess they can move about 10-15 degrees either way from center but I was hoping for much more. I`m wondering how much approximately is the maximum angle the ball joints on yours can move?

I found these ball joints. Unlike the tamiya these have no bolt on the ball and just from the picture they have a much greater degree of freedom.

I have used these ball joints, but I used smaller nuts, these. That creates some extra movement.

Further, I haven't done anything with the delta bot yet, no time :(
But I thought a cutter would be cool, so you could carve 3D objects from plastic foam or something.
Although I think the programming could get a little complex.

Helaas kunnen wij geen winkelwagen voor u aanmaken.

Wij kunnen geen winkelwagen voor u aanmaken.

Dit kan 2 oorzaken hebben.

Try it this way:

go to conrad.nl and seach for product number 223417 for the balljoints and numer 248778 for the m2 nuts.

Yeah. Those conrad guys are allergic to deep links; it looks like.
I am going to create reasons to use the phrase "Verder zonder cookies". Like a battle cry or something.

It would be a good battle cry for paranoid folk who keep cookies permanently switched off.

But what does the header mean: "We can't cart for you"?


As far as I understand it, the link you were following, contains a reference to a session for which you don't have the correct cookie. The page shows the wrong error message. It says: "We were unable to create a shopping cart for you." The two options state "you might be using an old link: retry loading the page" and "You might have cookies disabled: continue without cookies" but they both throw you to a home page.

My guess is that when someone tries to add an article to their shopping cart, but the session cannot be found, the website assumes you have disabled cookies in your browser and it shows this page.

Because the session reference is used in all URLs copied from the Conrad website, this effectively makes deep-linking directly to an article or product  impossible. 

Good shop, Conrad, but a lousy website. 

Remember the Soup Nazi in Seinfeld? Maybe it's like that. If you're gonna keep your cookies to yourself, then "No cart for you!"
...it was EXCELLENT soup.
