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.

Download and install processing from here. Start it up, then copy and paste all the code mcb posted and marked as the processing part. Save and compile. If it doesn`t work, you might have to change the com port.
The code's now compiling after the declaration of serialteller, "int serialTeller;" but when i burn the code onto arduino, nothins happening....i mean i shd be able to control the servos with ma mouse, but nothin happens. im kinda new to arduino.... plz help me out.
Did you install processing and run the code?

When I compile the code posted above, it's giving an error:

 In function 'void loop()':
error: 'serialTeller' was not declared in this scope

whats wrong?

 

serialTeller hasn`t been declared, so basically the Arduino doesn`t know what it`s supposed to be. In C you must declare variables before they are used.

I`m not sure what it is supposed to be so you might have to wait until the author comes back to respond. He did say it`s not in english, so if anyone knows what Teller means it could give a clue as to its purpose.

As a start try adding the line int serialTeller; up at the top with the other variables.

A good example of an industrial deltabot on BotJunkie : the FlexPicker.

Hi mjcbruin!

I found an interesting program in C language to calculate X Y Z based on the angles of the three servos and the other way around (you want to go to X Y Z, what angles must the servos have?) I translated this into a Visual Basic 6.0 program.

Would you be able to test this ? I plan to build my own Deltabot, but that will take some time...You are living in the Netherlands??

My name is Oscar Im new in this forum, Can you send me a source code that you have in C or VB 6.0 please?

At least it's another link back to LMR!!
