Dynamic test cases in Robotframework - How to assign return value from a keyword to a variable?

I found a way to create dynamic test cases in Robot framework using below post, and its working good.

Robot framework: Is there a way to write dynamic test cases?

However, the problem I am facing is with assigning the return value of the keyword to a variable. I could not find the syntax for it using dynamic format. I tried some options, but none of them worked.

For example, if I want to write in Robot Framework:

${Results}= | SSHLibrary.Execute Command | pwd
Log | ${Results}

Attempt 1: I wrote in the dynamic syntax as:

test.keywords.create('${Results}=       Execute Command', args=['pwd'])
test.keywords.create('Log', args=['${Results}'])

This gives me error:

No keyword with name '${Results}=       Execute Command' found.

Attempt 2: Then I tried:

Results = test.keywords.create('Execute Command', args=['pwd'])
test.keywords.create('Log', args=[Results])

It just prints the command, not the output.

Pls advise! Thanks in advance.
