Drones are capable of taking on many tasks. They are not always able to get through small openings though. Researchers at JSK Lab at the University of Tokyo have developed a flying robot, called DRAGON that changes its shape mid-air to pass through horizontal openings.
DRAGON can autonomously decide how to change given the space it has to pass through. It consists of linked modules with a pair of ducted fan thrusters. The above video shows these robots in action.
