All they do is stay in 1 spot. They move to face you when you're close to them and they'll say a few lines. When not nearby the Dalek's heads move left to right. The Cybermen make movements with their arms when they talk, and if I remember right K-9's tail wags and his head moves up and down. The Dalek Emperor's shell opens up and his head flies up and he reveals a laser gun when you get close to him.
