Abstract

An unmanned aerial vehicle includes a plurality of arms coupled along a body, each arm of the plurality of arms including: a linkage structure configurable in a first linkage state, a second linkage state, and a third linkage state. The vehicle can further include an actuation mechanism including: a ratchet gear having a contact surface that applies a lateral force against a leading link of the linkage structure to transition the linkage structure from the first linkage state to the second linkage state or the third linkage state; a bistable spring that transitions from a first spring state to a second spring state upon application of the lateral force against the leading link of the linkage structure; and a cable for straightening the linkage structure.
