Can more than one robot run on one machine?

Hi,

I need to know if we can have more than one robot on one machine running? The issue is I am using community edition, and when provisioning a robot it asks for username, which I am providing as my system username. When I am trying to add another robot, what to provide as username as if I use system username again, it gives error.
