Abstract

In recent years, with the booming development of the drone market, multi-rotor drones have quickly attracted the attention of consumers with their excellent control performance and convenient vertical take-off and landing characteristics. However, the current rotor drone landing gear has relatively stringent requirements on the terrain. Under special terrain conditions, due to the unevenness of the ground, drones often have problems such as rollover, which may lead to serious economic losses. Based on the design of traditional drone landing gear, this project has designed and adjusted the height adjustment and telescopic mechanism of the landing gear to meet the needs of terrain adaptation. Through in-depth analysis of key parameters, the engineering feasibility of these design improvements and the improvement effects brought about in terrain adaptation have been verified. This innovative design adjustment is expected to effectively solve the problem of safe landing of drones in complex terrain, providing strong support for them to play a greater role in a wider range of application scenarios.
