Abstract

Musca domestica, the common house fly, possesses a powerful vision system that exhibits features such as fast, analog, parallel operation and motion hyperacuity -- the ability to detect the movement of objects at far better resolution than predicted by their photoreceptor spacing. Researchers at the Wyoming Information, Signal Processing, and Robotics (WISPR) Laboratory have investigated these features for over a decade to develop an analog sensor inspired by the fly. Research efforts have been divided into electrophysiology; mathematical, optical and MATLAB based sensor modeling; physical sensor development; and applications. This paper will provide an in depth review of recent key results in some of these areas including development of a multiple, light adapting cartridge based sensor constructed on both a planar and co-planar surface using off-the-shelf components. Both a photodiode-based approach and a fiber based sensor will be discussed. Applications in UAV obstacle avoidance, long term building monitoring and autonomous robot navigation are also discussed.
