Design Of Bionic Wall Surface Automatic Takeoff And Landing System For UAV

The outstanding maneuverability of drones has made it widely used in more and more fields,but its large flight power consumption and limited battery capacity have led to insufficient battery life,and it cannot perform tasks that require long or long-distance flight.On the other hand,with the continuous development of urban construction,the ground space is becoming more and more valuable,while the traditional way of taking off and landing can only be performed on plane space,and the efficiency of taking off and landing is not high.Letting the drone land on the wall instead of hovering in the air can effectively improve this problem.At present,most of the wall-fall researches focus on the adsorption method and mechanism design.Lack of in-depth research on control strategies for takeoff and landing and handling of collision potential energy,UAVs can only land on vertical walls at a relatively slow speed.The adaptability of the wall tilt is single,it is difficult to cope with the severe collision potential energy during rapid landing,and it cannot meet the higher wall take-off and landing requirements.Although the drone's wall takeoff and landing technology has made great progress at present,in terms of agile take-off and landing,energy consumption,and wall tilt adaptability,there are still areas for improvement.Inspired by the bionics of bees landing on flowers to collect pollen,this paper proposes a bionic wall automatic take-off and landing system based on a four-axis drone.We analyze the wall landing process,through in-depth study of the control strategy of landing and the problem of potential energy conversion,the take-off and landing mechanism and the corresponding landing control strategy and algorithm were designed.At the same time,the processes of landing collision and ejection from the wall were modeled separately and the dynamic analysis was performed.The simulation verified the reliability and correctness of the model.Finally,the slow,medium and fast take-off and landing experiments were successfully carried out on wall surface with different tiltangles.The results show that the drone's wall take-off and landing agility and tilt adaptability are significantly improved,and the maximum collision speed can reach 3.4m/s,and it can take collaboration be more stable or recover to initial state faster.This conclusion conforms to the target of our experiments and it give a valid method or theory for realizing fast and stable human-robot collaboration.off on its own power.The take-off and landing system has the characteristics of simple and clever structure,stable take-off and landing,and easy implementation.It has broad application prospects in aircraft wall take-off and landing research and monitoring and reconnaissance.
