This paper shows one kind of VOR's (vestibule ocular reflex) implementation. Here, the VOR is built and designed with the instrumentation and automation of an irrigator system. This is done by water irrigation at three different temperatures, in one or both ear cavities, which it can stimulate internally any of the 3 semicircular canals of the vestibular system. This fact produces a measurable Nystagmic response at a glance. The irrigator is formed by analog instrumentation item coupled to a PLC, for its automated operation.
