It is Zeus' anathema on biomedical engineering that we should agonise between the Scylla of the simulation of the physiological and anatomical findings and the Charybdis of the efficient implementation of a system. Previous simulations on the addition of the perceptual velocity tracking of a target to a biomimetic controller developed by Galiana allow the implementation of a novel oculomotor system (OCS) in a hardware device comprising two cameras and a neck, each of which able to produce yaw and pitch movement. The robotic system uses visual inputs and a variety of movements in order to track targets, namely slow pursuit (slow phase), saccades (fast phase), conjugate and vergence. The addition of prognosis and memory to the controller, leads to the need for new tactics to be presented that address the problem of fixating a target more efficiently. Since the length and the flatness of the pursuit bandwidth of the new controller are essential for the minimization of the need for saccades, a greater harmonization among the parameters of the controller is basic. The resulting OCS can now be used to label with a significance factor each target presented on the visual field and track the one which is the most conspicuous. The intensity and the speed of the target are the criteria used to select a target and to alternate the alertness state of the robot.
