How to make an AI model move like a normal Roblox character?

I have a Model, with a Humanoid and all required parts in a normal Roblox character, but it's a NPC. How would I make it walk, and animate just like a normal Roblox character would? AI in a sense.

This model works pretty well - check out the INtelligence script.

What you have to do is put a animation script into the model, to get the animation script you can look through the toolbox or just go into playmode and then copy the one inside of your player then paste it into the model, hope this helped you!
