Problems solved by technology

It still cannot adapt to the terrain with large slope and large unevenness, and it cannot guarantee that the body is in a horizontal posture under uneven terrain, which is not conducive to the take-off and landing of the UAV.
Moreover, for the above-mentioned invention, in order to meet the requirements of terrain adaptation, the adaptive landing gear structure is often more complicated, and the weight of the structure is relatively large, and the increase in the weight of the UAV will greatly shorten its endurance
On the other hand, conventional multi-rotor UAVs can only change the spatial position by flying or artificial movement. In application scenarios with narrow exploration spaces such as mines and tunnels, the space required for flight often cannot be met. It is difficult for the drone to continue to travel and complete the flight mission
To sum up, the multi-rotor UAVs in the prior art have relatively weak ground self-adaptive ability, low intelligence, and strong dependence on operators. Application scenarios in narrow spaces

Abstract

The invention discloses a variant six-rotor unmanned aerial vehicle with terrain self-adaptive take-off and landing and walking functions, and relates to the field of six-rotor unmanned aerial vehicles. The unmanned aerial vehicle can stably take off and land under complex terrains and move on the ground. The unmanned aerial vehicle comprises a mounting platform, a control box, a rotor wing and asupport arm. Six supporting arms are symmetrically installed along two side edges of the mounting platform, each supporting arm is provided with three sections and two joints, and rotors are installedon the supporting arms. A control box on the mounting platform is connected with and controls the rotors and the supporting arms, and a landing posture and coordinates of an aircraft are autonomouslyand intelligently adjusted through data returned by a distance sensor and an angle sensor. The unmanned aerial vehicle has design characteristics that a vehicle body and an undercarriage are integrated, an intelligent autonomous landing control system is provided, meanwhile, a six-foot bionic structure design is utilized, a complex terrain adaptive capacity and an additional walking capacity of the unmanned aerial vehicle during landing are improved, and an application prospect of the unmanned aerial vehicle is broadened.

Description

technical field [0001] The present invention relates to the field of six-rotor unmanned aerial vehicles, in particular to a variant six-rotor unmanned aerial vehicle with terrain adaptive take-off and landing and walking functions. Background technique [0002] The application range of multi-rotor drones involves all aspects of daily life, especially because of its outstanding small size, convenient and easy-to-operate features, its application occasions are becoming wider and wider. However, with the diversification of applications, the multi-rotor drone's endurance and complex terrain take-off and landing capabilities have been put forward higher requirements. [0003] Traditional multi-rotor UAVs with sled or wheeled landing gear have higher requirements for take-off and landing ground. Due to the lack of terrain adaptive ability, when taking off and landing on complex ground, the operator often needs to make additional adjustments based on experience and control technol...
