6.3. Coordinated work objects

About work objects

This section will only describe how to make a work object coordinated with a mechanical

unit. For a detailed description of work objects, see wobjdata - Work object data in Technical

reference manual - RAPID Instructions, Functions and Data types.

What determines coordination?

When declaring a work object, the second attribute (

ufprog

) and the third attribute (

ufmec

)

determine if the work object is coordinated to any mechanical unit.

robhold

robhold

defines if the work object is held by the robot in this task.

robhold

is normally set to

FALSE

. The task of the robot that holds the work object (where

robhold

would be set to

TRUE

) does not have to declare it unless a stationary tool is used.

ufprog

If the work object is stationary,

ufprog

is set to

TRUE

If the work object can be moved by any mechanical unit,

ufprog

is set to

FALSE

ufmec

ufmec

is set to the name of the mechanical unit that moves the work object.

ufprog

is set to

TRUE

ufmec

can be left as an empty string (no mechanical unit can move

the work object).

Example

This is an example of a work object that can be moved by a mechanical unit with the name

STN_1:

PERS wobjdata wobj_stn1 :=

[

FALSE

"STN_1"

[ [0, 0, 0], [1, 0, 0 ,0] ],

[ [0, 0, 250], [1, 0, 0, 0] ] ];
