UNIVERSAL ROBOTS How to assign a variable in a pop up message

Zach 2018-10-31

I have been assigned a task where we will want to have a pop up where an operator can assign a variable. Essentially we would want the operator to enter a variable into a popup and that would call for a specific sub program. Just trying to make one program that can accomplish multiple tasks.

Thanks in advance!!!

Edit: I know how to create a user set variable, but I am wanting to do something a little more advanced. I want to the user to type A2 and have the robot complete the A program and then the 2 portion of the program.

So are you asking how to split the string "A2" for example into and A and a 2?

Yes exactly.

There are currently no tools available on the robot that do string manipulation, and I do not believe you can access individual characters in the string using array methods either because the string is not stored as a list of any sorts, last I checked. I just tried in version 3.6 and its not there, may be coming in future releases as there have been a lot of requests to UR to add some string manipulation tools

Matthwe92, but how do you write to a simple variable from a pop-up

Answering my own question. I did a message popup with instructions to enter the integer on the next pop-up. The next line of code was operator assignment of a variable which automatically pops up number field entry screen. All is well.

@GrantG_1 you could use the script code function: str_at(src, index) which provides direct access to the bytes of a string. Where src: source string, and index: integer specifying the position inside the source string.

Example:

str_at("A2", 0)
- returns "A"
str_at("A2", 1)
- returns "2"

I want to separate the contents of string
Example: (132.78, 45.7, 78.9)
How can I do this ?

Hi,

The short answer is that you compare each character with the search character and you store the position of it.
For example:
"(" will be found only at the beginning.
")" will be found only at the end.
"," will be found at each end of a parameter.

Then you need to build up each parameters.

This is a short answer but this is long to do programming each possibility with what "Kaleb" proposed : "str_at("A2", 0) " .

Maybe it would be easier to use I/O inputs or to have a PC with a simple interface to send socket messages.

The other way is the easiest and was proposed by "GrantG_1 "
Make a sequence of popup to ask and retrieve answers.
"I did a message popup with instructions to enter the integer on the next pop-up. The next line of code was operator assignment of a variable which automatically pops up number field entry screen. "

String management can be time consuming, I suggest trying a work around that match production needs to "Start Production Faster".

Hope this helps.

@samsha are you sending that string in from another device like a PC or camera? If so, simply change the () to [] and the robot will receive a list and then you can simply use the index position of each of the three elements (0,1,2). We do this from cameras and other devices to make getting to the data very simple. If the operator is entering that, simply have them change the () to [] and it should work the same way
