Mothlike drone hovers and tracks light using natural feedback instead of AI

University of Cincinnati researchers developed a flapping-wing drone that mimics moth flight to track and hover around moving light sources without GPS or AI. The drone uses an "extremum-seeking feedback system" that makes constant micro-adjustments through natural feedback loops, similar to how insects maintain flight control with tiny brains. This breakthrough could enable smaller, more efficient surveillance drones and reveals how hovering creatures achieve stability through simple biological mechanisms rather than complex computational systems.
