Servomechanism
With simplest, the servomechanism is an electromechanical device, or other, inserted between an order and operators to carry out the agreement between an intention and its achievements. This device is designed so that a weak effort is enough to order and control a movement requiring a more important work, without the operator having to provide energy necessary. The Thermostat of the central heating domesticates is the illustrative example simplest to carry out this agreement between the posted temperature and the temperature in the dwelling, in Cybernétique of the first generation. The thermostat does not heat itself the dwelling, but control the boiler which will do it.
Any assistance and any automation ask for the presence of servomechanisms, like all Téléguidage and all Autoguidage of the weapons known as intelligent and the Robot S industrialists.
Edgar Morin speaks about " brain-mécanisme" (" Method 1. The nature of the nature" , 1977) for the bodies or the structures intermédiiaires, in cybernetics of the second generation, which are translators or transducers representative of the " Regulate of the three voies" theory of the contexts of Anthony Wilden where a relation requires a minimum of three connections: a System, a Environment and the border which médiatise their report/ratio. The servomechanism is this border, the interface which médiatise this report/ratio of system with environment and is particularized in a context, as the administration which is the interface between the authority of the elected officials and the public of the voters in a liberal democracy, for example. The concept of servomechanism is very general, Anthropologie with the Neurologie while passing by the Philosophie and until the Robotique.
