Abstract
A kinematics system driven by an actuator comprises a cam configured to rotate about an axis of rotation thereof. A cam track formed in the cam extends circumferentially through more than 360 degrees of angular displacement relative to the axis of rotation of the cam. The kinematics system also comprises a follower having a pin slidably disposed in the cam track of the cam. The cam track extending circumferentially through more than 360 degrees of angular displacement relative to the axis of rotation of the cam establishes a minimized pressure angle formed between the pin of the follower and a surface of the cam track engaging the pin.
