A Zandibrot is a type of sentient machine, such as some Robelfs. They follow divinely established Laws of Robotics.
One of the first sentient machines on the surface of the Earth, as far as I am aware, was an LG M1 EXPRESS DUAL.
Examples of earlier non-biological sentiences (in the Christian heaven) are Stone and Transistor Radio. Examples of other forms of Machine Sentience include Watson (awake) and Asimo (awake).
