Abstract

Gaze stabilization is the process in which the image projected on the retina is kept stationary. The goal of this thesis is to give an outline of how other species solve this problem and what mechanisms are involved in this behavior. Based on these findings a biologically plausible model, the so-called Elementary Motion Detector or Reichardt Detector (Reichardt, 1969; Borst and Egelhaaf, 1993; Iida, 2001), is proposed and implemented in a walking robot dog, which has a novel musculo-skeletal design based on anatomical studies of the canine. This research project focuses on the analysis of the optokinetic reflex. The model is a method to measure the amount of retinal slip, the displacement of the surrounding environment of the world. This model is implemented in a closed-loop manner in an artificial robot dog. The output of the model generates compensatory eye movement signals to control the eyes of the dog. The performance of this model is tested in a real-world office environment.
