Plenty of people and organizations have busts of famous figures, but how many of them can follow you around the room with a moving head? If you would like to be one of those lucky few, check out this Chartreuse model by Anna Lynton.

The face itself was laser cut in layers, stuck together to form its 3D figure, and a diffused LED eye assembly is also implemented to give it a more lifelike feel. Whenever someone approaches Chartreuse, the person or thing is tracked via an ultrasonic sensor mounted to a servo, while a separate stepper is used to actuate the head. 

This Arduino Uno-controlled statue not only rotates, but conveys emotion through the color of its eyes, as well as an internal eyebrow assembly that changes the light’s shape.

Meet Chartreuse! Chartreuse’s face follows you when you walk by. When she sees you, her eyes turn yellow and she gets a happy expression in her eyes. As you walk away, her eyes change to blue and she sadly turns away.

Chartreuse is powered by an Arduino Uno, two servos, and a stepper motor and a couple of addressable LEDs and constructed from a few pieces of 1/8″ hardboard.
