How can I make a series of actors follow one another precisely

I see, thanks for notifying me.
Yes, I’m working on a university project , the aim is to create a Sound toy.
I am interested in finding out how to get several actors to follow each other in a snake like manner. So that anything behind the “Head” would follow in a mimicking fashion. I just started using the Unreal engine and i am using Blueprints. So far I’ve understood how to automate doors slides and lights, how to build structures, adding sound to objects, motion and how to use most of the tools. Unfortunately i could not find any useful information for the actors to follow each other. Could you help?
