Abstract
In a moving apparatus, flapping angle of a front wing shaft is γ+Δγ/2, and the flapping angle of rear wing shaft is γ−Δγ/2. Specifically, amplitude difference between front wing shaft and rear wing shaft is Δγ. Further, the flapping motion of front wing shaft is represented by sin (τ+φ/2), and the flapping motion of rear wing shaft is represented by sin (τ−φ/2). In other words, phase difference between the front and rear wing shafts is φ. Further, amplitude difference Δγ and phase difference φ are each represented by a function using a common parameter. Therefore, a control portion can independently change the amplitude difference Δγ and phase difference φ, so as to variously change a torsion angle formed by a tip end portion of the wing and a prescribed phantom plane. Thus, a moving apparatus that can make an efficient transition from hovering to forward or backward flight can be provided.
