Four-rotor unmanned aerial vehicle based on Raspberry Pi control system

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses a four-rotor unmanned aerial vehicle based on a Raspberry Pi control system. The four-rotor unmanned aerial vehicle comprises an unmanned aerial vehicle body, and four balance rotor sets are arranged on the outer side of the unmanned aerial vehicle body; a control mainboard, a storage battery, a GPS position indicator, a data storage module and a wireless transceiver are arranged in the unmanned aerial vehicle body; the storage battery is electrically connected with the control mainboard, unmanned aerial vehicle racks are arranged on the two sides of the bottom of the unmanned aerial vehicle body, a camera balance mechanism is arranged at the position, between the two unmanned aerial vehicle racks, of the bottom of the unmanned aerial vehicle body, and landing frame assemblies are arranged below the two ends of each unmanned aerial vehicle rack. Through the cooperative use of the adjusting mechanism and the laser range finder, the four landing frame assemblies can synchronously make contact with the ground together, so the unmanned aerial vehicle can land accurately and stably, the unmanned aerial vehicle is prevented from being damaged due to inclination and rollover when landing, and the protection of the unmanned aerial vehicle is improved.

Description

Technical field [0001] Technical Field The present invention relates to unmanned aerial vehicles, in particular to a four-rotor UAV Raspberry Pi based control system. Background technique [0002] Four-rotor UAV is a compact structure, small size, smooth flight, flexibility advantages, multi-rotor UAV can achieve a variety of complex tasks, in military and civilian fields have a very wide range of applications. Raspberry Pi micro-computer as an affordable, is widely used in hair things, the field of open source electronics and robotics, unmanned aerial vehicles used in extremely broad. [0003] The current four-rotor UAV during the ups and downs, especially in the field work and landing UAV can not be effectively based on the actual situation of the landing site, landing gear flexibility in adjusting the distribution structure, resulting in a drone after landing prone to tilting and even rollover phenomenon, resulting in damage to the drone, the ability to adapt to the field work...

AI Technical Summary

Problems solved by technology

[0003] When the current four-rotor UAV is taking off and landing, especially when it is operating in the field and landing, the UAV cannot effectively adjust the distribution structure of the landing gear flexibly according to the actual situation of the landing site, thus causing the UAV to operate in the field. After landing, it is easy to tilt or even roll over, resulting in damage to the UAV. For the adaptability to the field working environment, a quadrotor UAV based on the Raspberry Pi control system is needed to improve the above problems.
