9 Mothers
AI-powered counter-drone defense turrets
9 Mothers builds autonomous AI weapon systems like EDDA, a low-cost counter small unmanned aerial system (C-sUAS) turret. It detects, tracks, and neutralizes fast-moving small drones at close range using computer vision, acoustics, and robotics. Targeted at military and defense for modern battlefield protection against cheap drone threats.
