Charater creation help

Hello there, guys and girls. I have a couple of simple questions. I have created a custom character and rig, imported into the UE4 in fbx format. The animations and model is working good but I’m unable to control it.

How do I move my character around/

How do I create an AI from it?

Epic has a great tutorial on the basics of AI. Basics of AI | Live Training | Unreal Engine - YouTube
