Bulgy/Behind the Scenes

'Regular Model'
Bulgy' model was built to run on Styrofoam road and was painted in glossy car body paint.

Seven different facial expressions were worn by Bertie on screen. The faces were first sculpted in clay and from that resin casts were made using a silicone mould. A radiator was attached to each of Bulgy's facemasks.

The eye mechanism had two servos, one for up and down movement and one for left and right movement. The up/down servo was attached to the body. The left/right servo had a rod attached to the arm, which connected to a bracket. The eye balls were coupled to the bracket and locked in by the face-plate, so whenever the servos were powered, the eye balls would move however the crew member desired.

'Close-up Model'
Close-up shots of Bulgy was required for scenes where he had to interact with close-up scale figures. they're are also used for interior shots.
