you don't really need a real robot, but assign some "time cost" for various actions which depends on spatial distance and type of action and if it is a different action than the previous action. humans are really fast when for example splitting a group of units but performing multiple different actions on different areas on the screen or even multiple screens takes a lot longer. They don't need to fully emulate human behaviour but getting somewhat close would really show how strong teh AI is tactically and strategically without superhuman micromanagement.
