This is an early prototype of the ESRA mechanism (Notice the lack of a nose). The body is made from 1/4 inch aluminium. Pin placement is not yet optimized in this model so it's sad face is kind of funny. Apart from that, the code should work just fine on the newer ESRA models.

	Expression shown if a person or object gets around 1-2 feet from the sensor.
	Resting state of the ESRA.
	Expression shown if a person or object gets less than 1 foot from the sensor.
	ESRA hides his eyes and hopes you go away.
