This work addresses the problem of learning stabilization reflexes in robots with moving eyes. Most essential in achieving efficient visual stabilization is the exploitation/integration of different motion related sensory information. In our robot, self-motion is measured inertially with an artificial vestibular system (gyroscopes) and visually by(More)
Stabilization of gaze is a major functional prerequisite for robots exploring the environment. The main reason for a steady-image" requirement, is to prevent the robot's own motion to compromise its visual functions". In this paper we present an artiicial system, the LIRA robot head, capable of controlling its camerasseyes to stabilize gaze. The system(More)
Stabilization of gaze is a fundamental requirement of an active visual system for at least two reasons: i to increase the robustness of dynamic visual measures during observer's motion; ii to provide a reference with respect to the environment Ballard and Brown, 1992. The aim of this paper is to address the former issue by i n vestigating the role of(More)
We present a binocular robot that learns compensatory camera movements for image stabilization purposes. Most essential in achieving satisfactory image stabilization performance is the exploitation/integration of different self-motion information. In our robot, self-motion is measured inertially through an artificial vestibular apparatus and visually using(More)
Robot systems that rely on vision as their main sensory capability need to be able to cope with changes in the visual environment and to manage a wide eld of view. Moreover, in order not to loose real-time response capabilities, selective visual sensing is indeed highly desirable. The \built-in" selection in space and time provided by space variant sensors(More)
* We propose that the development of causality can be seen as a primitive for understanding and constructing complex systems either biological or artificial. Furthermore, we put forward a view of development in terms of the control of complexity. Although some of these elements are at the moment speculative or barely outlined, the theoretical test and(More)
