The first artificial automatic regulatory system was a [[water clock]], invented by the mechanician [[Ktesibios]]; based on a tank which poured water into a reservoir before using it to run the mechanism, it used a cone-shaped float to monitor the level of the water in its reservoir and adjust the rate of flow of the water accordingly to maintain a constant level of water in the reservoir. This was the first artificial truly automatic self-regulatory device that required no outside intervention between the feedback and the controls of the mechanism. Although they considered this part of engineering (the use of the term ''cybernetics'' is much posterior), [[Ktesibios]] and others such as [[Hero of Alexandria|Heron]] and [[Su Song]] are considered to be some of the first to study cybernetic principles.
