According to @ai_darpa, researchers at the University of Pennsylvania have developed ModQuad, a modular quadrotor system where self-assembling flying robots dock mid-flight to form larger, cooperative aerial structures (source: ai_darpa on Twitter, Dec 25, 2025). Each cuboid drone attaches via flat faces, enabling units to connect, fly, and share control as a single, stable entity. This AI-enabled system represents a breakthrough in aerial robotics, offering scalable, adaptive drone swarms for practical applications like autonomous construction, disaster response, and logistics. ModQuad's distributed control and structural flexibility highlight significant business opportunities, especially in industries seeking modular, AI-powered drone solutions (source: ziegler.substack.com).
