South Korean researchers have developed a drone designed to stay level when transporting goods over many kinds of surfaces. A team at Seoul National University of Science and Technology built a prototype, or test model of the drone. The team recently demonstrated the aircraft for reporters from Reuters. The prototype has a transport carrier attached to a drone structure. It is supported by several propellers and rotors that control its height, speed and direction in the air. The aircraft has a handle workers can push to guide it where it needs to go. Members of the development team showed how the drone can keep itself level while floating, even when transporting goods up or down stairs. Leaders of the research say the drone is programmed to predict human actions for effective interactions.
