The results of this study are an evaluation of the mechanics of motion of a weight loaded Manduca sexta Hawkmoth during flight using accelerations recorded with an onboard sensory system. Findings indicate that these ‘normal’ flapping insects maintain relatively fixed body frequencies in both free and weight loaded flight, which correspond with the driving frequency, or wing beat frequency. Within the analysis, a presence of a harmonic body frequency at twice the wing beat frequency was also discovered. The conclusions from this study indicate an average excess muscle power of over 40mW available in free, unloaded flight. Stability robustness of these flapping insects in flight using the results of a large payload disturbance, 856mg or nearly half to one-third the mass of insect, is demonstrated, and their usefulness as platform for cyborg MAV (CMAV) development is presented.
