Extended Data Fig. 1: Wing deployment kinematics of beetles.
From: Passive wing deployment and retraction in beetles and flapping microrobots
a,b, At the end of the partial release (phase I of the deployment), the hindwing experiences decreasing oscillations around the equilibrium position, δh,base = 48.5 ± 0.7°: (a) elevation angle (b) and angular rate. c, Amplitude of the first oscillation (shown in a) is proportional to the releasing rate of the hindwing in b. Red line denotes the linear fit. d, Elevation angles of the elytron (orange) and the hindwing (dark blue). The time instant was set to 0 s when the elytron started elevating.
