Problems solved by technology

However, due to the low payload of the miniature quadrotor aircraft, the weight of a general high-performance on-board computer will exceed its maximum load. Although the weight of a low-performance on-board computer is low, its processing performance cannot meet the requirements of its autonomous flight.

Embodiment 1

[0025] This embodiment provides a quadrotor aircraft, which includes a body 1 , a motor 2 and a circuit board 3 .

[0026] The body has a center-symmetrical structure, and it includes a carbon fiber plate, a carbon fiber rod and a landing gear. The carbon fiber plate has two layers. The landing gear is fixed on the bottom of the carbon fiber plate. In this embodiment, the landing gear can be made of engineering plastics, and the landing gear made of engineering plastics is very light in weight, good in flexibility, and can withstand large deformations. Absorbs a lot of impact when landing.

[0027] The undercarriage includes two semicircular buffer bars and four cross bars; the two semicircular buffer bars are parallel to each other, and the two semicircular bars are fixed to the two semicircular buffer bars. The middle part of the buffer rod, the carbon fiber plate is fixed on the two cross bars in the middle part of the buffer rod, so that the carbon fiber plate is located ...

Abstract

The invention discloses a four-rotor aircraft, comprising a body, a motor and a circuit board. The circuit board is provided with a flight control system, and the flight control system comprises a main control computer and an attitude controller; the main control computer is an on-board computer. According to the four-rotor aircraft, the low-performance on-board computer is installed on the attitude controller of the four-rotor aircraft to connect with a wireless network built by a wireless router through a Wi-Fi module, so as to build a network framework based on an ROS (robot operating system), then send various flight data to the ROS network, and then transmit the flight data to a PC (personal computer) of a ground station; the PC processes a large amount of the data, and calculates the corresponding control instructions to control the flight of the four-rotor aircraft. Therefore, the calculating amount of the on-board computer is relatively small, and the requirement of the four-rotor aircraft for autonomous flight is met.

Description

technical field [0001] The invention relates to an aircraft, in particular to a quadrotor aircraft. Background technique [0002] The autonomous flight of micro quadrotor aircraft is one of the hot topics of current research. However, due to the low payload of the miniature quadrotor aircraft, the weight of a general high-performance on-board computer will exceed its maximum load. Although the weight of a low-performance on-board computer is low, its processing performance cannot meet the requirements of its autonomous flight. Contents of the invention [0003] The purpose of the present invention is to provide a quadrotor aircraft, which adopts a low-weight on-board computer, and can satisfy its autonomous flight. [0004] The present invention solves the technical problem by adopting the following technical solutions: a quadrotor aircraft, which includes a body, a motor and a circuit board; [0005] The circuit board is fixed on the body; the number of the motors is fo...
