Addressing a single value in an array

gianluigi

Hello all,

I'm trying to retrieve each individual joint angle from a jointtarget data, which is off the form:
jpos:=[[-10, 80,-30, 20, 0, 0] , [9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]];

How do I address these values to a variable? For instance I want to assign each of the joint angle data to different variables like;
q1=-10;
q2=80;
q3=-30;
q4=20;
q5=0;
q6=0.

Thank you,
Gianluigi

Hi Gianluigi,

To retrieve the elements from the jointtarget is not hard at all.

We know the structure of a jointtarget is of the form;

 

< dataobject of jointtarget >

  < robax of robjoint >

      <rax_1 of num >

      <rax_2 of num >

      <rax_3 of num >

      <rax_4 of num >

      <rax_5 of num >

      <rax_6 of num >

  < extax of extjoint >

    < eax_a of num >

    < eax_b of num >

    < eax_c of num >

    < eax_d of num >

    < eax_e of num >

    < eax_f of num >

 

Thus, to get the angles of robot axes from jPosCurrent...

 

PERS jointtarget jPosCurrent; 

PERS num J1;

PERS num J2;

PERS num J3;

PERS num J4;

PERS num J5;

PERS num J6;

 

J1:=jPosCurrent.robax.rax_1;

J2:=jPosCurrent.robax.rax_2;

J3:=jPosCurrent.robax.rax_3;

J4:=jPosCurrent.robax.rax_4;

J5:=jPosCurrent.robax.rax_5;

J6:=jPosCurrent.robax.rax_6;

I remark.

 

If you use PERS remember to initilise value in decleration

 

PERS Num PERSNume := Value;

Well, it was like rocket science to me :P

Thank you so much BigM and Klaus!
