Object spinning when key is not pressed

so because i am currently using an actor component and not a character component, it doesn’t want to connect as the target. to be specific on what i want this to be, this will turn into an robotic arm that can rotate on its base and eventually rotate on its pivot points for joints. so a non-moving camera aimed at this actor, and the actor being able to move on key press.
i don’t have anything set up as a character because i don’t really need a character for this case. any clues on what i should do to achieve this? should i make the arm a character fo a pawn instead, or is it ok to be an actor?
