The stroke-cam flapping mechanism presented in this paper closely
mimics the wing motion of a hovering Rufous hummingbird. It is the
only lightweight hummingbird-sized flapping mechanism which
generates a harmonic wing stroke with both a high flapping
frequency and a large stroke amplitude. Experiments on a
lightweight prototype of this stroke-cam mechanism on a 50 mmlong
wing demonstrate that a harmonic stroke motion is generated
with a peak-to-peak stroke amplitude of 175° at a flapping frequency
of 40 Hz. It generated a mass lifting capability of 5.1 g, which is largely
sufficient to lift the prototype’s mass of 3.39 g and larger than the
mass-lifting capability of a Rufous hummingbird. The motor mass of a
hummingbird-like robot which drives the stroke-cam mechanism is
considerably larger (about five times) than the muscle mass of a
hummingbird with comparable load-lifting capability. This paper
presents a flapping wing nano aerial vehicle which is designed to
possess the same lift- and thrust-generating principles of the Rufous
hummingbird. The application is indoor flight. We give an overview of
the wing kinematics and some specifications which should be met to
develop an artificial wing, and also describe the applications of these
in the mechanism which has been developed in this work.
