Midair assembly of modular drones: Brown University's new project compared with Penn ModQuad

A Reddit r/robotics community post discusses a recent modular drone midair assembly project from Brown University and compares it with ModQuad, presented by Penn GRASP Lab at ICRA 2018, which demonstrated modular quadrotors docking in midair and flying cooperatively as an assembled structure. The poster focuses on key advances in the new work regarding vehicle configuration, control, and post-assembly system capabilities, and seeks the community's opinions.
