“Moth: A Low-cost IR-based Approach Towards Autonomous Precision Drone Landing” was recently accepted to ICRA 2026.
In this paper, we propose Moth, a low-cost infrared light-based solution that targets precise and efficient landing of low resource microdrones. Moth consists of an infrared light source at the landing station along with an energy-efficient photodiode (PD) sensing platform attached to the bottom of the drone. At a cost under 83 USD, Moth achieves comparable performance to vision-based methods but at a fraction of the energy consumption and computation. Moth requires only three PDs without any complex pattern recognition models to land the drone accurately, under 10cm of error, from up to 11.1 meters away.
