While viewing a slideshow of the Aldebaran Nao images, it can be observed that changes in the orientation of the robot arm are caused only by the shoulder
	and elbow movements. While each of the shoulder and elbow joints have more than one degrees of freedom, in the present scenario, only one degree is being
	exercised for each joint. That adds up to 2 degrees of freedom, which is exactly as observed after isomap dimensionality reduction.
