Sorry for contributing so late, But it might help others

You can do it, using a framework of robot framework, called RF Swarm, where you need to clone it from github, install rfswarm manager, agent just for running the test suite, you can also install reporter for html or doc report, also there will be logs in the logs directory with individual logs for a individual robot, the installing file will be there clone directory. Using RFSwarm, will help you to exert load of 25 to 40 robot if you have free 6 to 8 gb of ram, so you should have 16gb ram in you local machine (laptop/pc), as robot use selenium for UI testing, so the chrome browser eats a lot of ram when run in numbers. Suggestion to use chrome headless when performing load testing.
