The creature effects for Tobe Hooper's 1986 remake of Invaders from Mars were designed by Stan Winston, who left the supervision to Alec Gillis (future founder of Amalgamated Dynamics) as he had to supervise the creature effects on Aliens the same year.
The Martian drones were designed to be unlike a humanoid; Winston came up with an armature inside the suit, where two people could fit inside. The taller person would be walking backwards, while the little person sitting on the upper side of the armature would operate the mouth and forearms.
The suit had a miniature hidden camera and screen for the taller person to be able to see while walking backwards.
