A Robust Dual-Axis Virtual Reality Platform for Closed-Loop Analysis of Insect Flight

Abstract

Through evolution, insects have obtained magnificent skills to fly and navigate through cluttered environments. Many of these skills, which are utilized mid-air, often follow simple, yet robust and optimal algorithms, that may have useful applications in the field of unmanned aerial robotics. In this paper, we introduce a novel tethered flight platform for insects, capable of controlling the thrust and yaw in closed-loop conditions while exposing them to realistic visual stimuli. This enables precise reconstruction of the visual experience of the insect, allowing us to analyze and model visually guided behaviors of insects with precision and ease. We show this platform in action by exposing Queensland fruit flies (Bactrocera tryoni) to a realistic forest environment where the flies exhibit multi-modal behaviors at varying flight speeds.
