Abstract: An unmanned aerial vehicle apparatus (100) that includes an air vehicle assembly (150) that is at least partially enclosed within a protective enclosure assembly (120) The protective enclosure assembly (120) is typically at least partially elastic, to protect the air vehicle assembly (150) from bumps, collisions, and other similar occurrences. The enclosure assembly (120) can also facilitate the ability of the apparatus (100) to operate in a ground movement mode (114), such as a rolling mode (116), in addition to a flying mode (112).
