Applying RelTool when Calculating Positions from a RobTarget

RAPID Programming
1

Morning Forum members,
Subject tile relates primarily to needing to apply rotational values against a robtarget. i have a Taught point and calculate another Point that has no rotational values needed to obtain the center of a Part (for instance). Next i need to add parts to this application using the Center and applying Trans.X,Y,Z and some RZ to create a New Point, however the Reltool() is not applying the robconfig im asking for.
the source values are staying the Same for the rot and robconf , so im stumped on what i am doing wrong.
at present i have the lines of code broken out to attempt to understand my issue and should be able to just apply it all in the RelTool() function.

pLocPoint_RHPallet{1,1}:=pLocPoint{nPntPalletCtr_RH};
pLocPoint_RHPallet{1,1}.trans.x:=pLocPoint{nPntPalletCtr_RH}.trans.X+(nCaseWidthValue+nHalfCaseWidth);
pLocPoint_RHPallet{1,1}.trans.Y:=pLocPoint{nPntPalletCtr_RH}.trans.Y+(nHalfCaseLength);
pLocPoint_RHPallet{1,1}.trans.Z:=pLocPoint{nPntPalletCtr_RH}.trans.Z;
pLocPoint_RHPallet{1,1}:=RelTool(pLocPoint_RHPallet{1,1},0,0,0\RX:=0\RY:=0\RZ:=90);

Thanks for any help,
Alan Cannon

Single step through each instruction, observe the values that are being calculated before making the next step. Debugging in this fashion is often times the best way to get to that “aha” moment.

I am looking at this once more, put the original points rot into the array robtarget, then try the reltool.

4

this (destination{1,1):=source) does that.. im not following you thought

I got focused on this: “Point that has no rotational values needed”. I was thinking you were not putting the rot values in. Not needed, but yes, your first line will put the rot value into the array. SO Execute the first line in step mode, look at the array index position value, make sure that it matches. Then go step by step, checking values each time to see that they match what you expect. If not, that is what you have to figure out why.

pLocPoint_RHPallet{1,1}:=pLocPoint{nPntPalletCtr_RH}; ! this is an array position also? Are you sure where it is pointing?

You could also just do this:
pLocPoint_RHPallet{1,1}.trans.x:=pLocPoint_RHPallet{1,1}.trans.x+(nCaseWidthValue+nHalfCaseWidth);
pLocPoint_RHPallet{1,1}.trans.Y:=pLocPoint_RHPallet{1,1}.trans.y+(nHalfCaseLength);
This next one is not necessary, you already wrote in the z value.
pLocPoint_RHPallet{1,1}.trans.Z:=pLocPoint{nPntPalletCtr_RH}.trans.Z;
pLocPoint_RHPallet{1,1}:=RelTool(pLocPoint_RHPallet{1,1},0,0,0\RX:=0\RY:=0\RZ:=90);

ok i will line test these as soon as i can get past:
50419: Common base_frame error
Description
Task: Task1.
The Base Frame is moved by another task than the robot and could not be solved, reason 5:

  1. SingArea\Wrist not supported with MoveC.
  2. The Base Frame must be moved by first synchronized motion_group.
  3. Only one common Base Frame can be handled.
  4. Absolute Accuracy not supported with MoveC.
  5. The common Base Frame can only be solved in synchronized move.
    Program ref. /TeachCellPoints/TeachWorkObj3point_RHPallet/MoveJ/439.
    Actions
  6. Use SingArea\Off. The CirPathMode can also be used.
  7. Check Controller and Motion configuration.
  8. Use MoveL or remove Absolute Accuracy.
  9. Use MoveAbsJ.

My Entire app has a File:

Can you post your Backinfo file please?

Hi Alan,

If I use your code in RobotStudio, the function is running. Only thing I cant test is “pLocPoint{nPntPalletCtr_RH}”, array part.
I cant figure out the definition of nPntPalletCtr_RH.

But if for the test purposes I use

pLocPoint_RHPallet{1,1}:=pLocPoint{1,1};
pLocPoint_RHPallet{1,1}.trans.x:=pLocPoint{1,1}.trans.X+(nCaseWidthValue+nHalfCaseWidth);
pLocPoint_RHPallet{1,1}.trans.Y:=pLocPoint{1,1}.trans.Y+(nHalfCaseLength);
pLocPoint_RHPallet{1,1}.trans.Z:=pLocPoint{1,1}.trans.Z;
pLocPoint_RHPallet{1,1}:=RelTool(pLocPoint_RHPallet{1,1},0,0,0\RX:=0\RY:=0\RZ:=90);

Everything is working!!

Also try using following example
destination:=source;
destination.trans.x:=destination.trans.X+(nCaseWidthValue+nHalfCaseWidth);
destination.trans.Y:=destination.trans.Y+(nHalfCaseLength);
destination.trans.Z:=destination.trans.Z;
destination:=RelTool(destination,0,0,0\RX:=0\RY:=0\RZ:=90);

So in your case it would be
pLocPoint_RHPallet{1,1}:=pLocPoint{nPntPalletCtr_RH};
pLocPoint_RHPallet{1,1}.trans.x:=pLocPoint_RHPallet{1,1}.trans.X+(nCaseWidthValue+nHalfCaseWidth);
pLocPoint_RHPallet{1,1}.trans.Y:=pLocPoint_RHPallet{1,1}.trans.Y+(nHalfCaseLength);
pLocPoint_RHPallet{1,1}.trans.Z:=pLocPoint_RHPallet{1,1}.trans.Z;
pLocPoint_RHPallet{1,1}:=RelTool(pLocPoint_RHPallet{1,1},0,0,0\RX:=0\RY:=0\RZ:=90);

If this is not working, then I would say its the issue in line

“pLocPoint_RHPallet{1,1}:=pLocPoint{nPntPalletCtr_RH};”
Or later on in program..

Please report if you fixed it, and what was the issue.

Thanks

Afternoon, And thanks for assisting. At tpresent the Issue is when i attempt to goto these positions from the Pallet Center is says nope Out of reach. I can Jog directly there which for this conversation it is \Rz:=+90 and a Slight x and Y
I can use the Goto from this position back to the Center and that works as well..

To step back a little. my Original Config (Inverted and on a Rail (MOC) file data was incorrect causing the original thread o start, but i fear i still have some addditional issue i am un aware of causing my plight

Hi Alan,

Jog and move instruction is not the same, also the movement of the robot is not the same if you use MoveJ, MoveL or MoveC.
From your post, I would say that you can complete move with MoveJ, and I guess that with MoveL/MoveC instructions robot would need to go out of the Axis limits to complete the move. Which is not possible, so he gives error.

Best regards,
Danijel
