Controlling character using custom script

Hello everyone

I have an assignment for building some sort of interface for ai programmers. I have a simple game (in blueprints) , all I need is to give different commands to a character, when i take different logs from the game. it should give an opportunity to program ai in such manner, to a person which does not have UE4 installed. How can i complete such a task? I really don’t know where to start.
