Endurance is the critical problem that most Unmanned Aerial Vehicles (UAVs) will definitely encounter. By learning from birds in nature that perch to reserve energy, however, this problem could probably be solved. The purposes of this paper are to gain inspiration from bird”Ēs perching in a more systematic way, to further propose a design of bio-inspired adaptive perching mechanism, and to investigate its functionality and reliability in applications. Principles are first derived from anatomy analysis of perching birds as a guide. The perching sequence of a UAV is then generalized into 3 stages, namely pre-perching, perching and de-perching. Design specifications are presented, reliability experiments are performed and results are analyzed.
