'ModQuad' Flying Modular Structure Self-Assembles in Midair

Researchers from the University of Pennsylvania's Modular Robotics Lab (ModLab ) introduce ModQuad - a flying modular robotic structure that can self-assemble in midair and cooperatively fly. The structure is composed by agile flying modules that can easily move in a three dimensional environment. The module is based on a quadrotor platform within a cuboid frame which allows it to attach to other modules by matching vertical faces.
