Embodiment Construction

[0027] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0028] (1) The overall structure of the fully autonomous control indoor environment obstacle avoidance navigation micro air vehicle of the present invention is as follows: figure 1 , figure 2 and image 3 As shown, it includes airframe, environment recognition sensor group, power unit group and control module. Wherein the body includes a middle fuselage 8, four struts 2 installed on the fuselage, a protective frame 3 and a frame 1. In order to reduce the weight of the body as much as possible and ensure the structural strength of the load, all parts of the body are made of carbon fiber composite materials.

[0029] (2) The power unit group includes four independent power units installed on the outer ends of the four struts 2 of the body, and each power unit includes a brushless motor 4 , an electronic governor 5 and a propeller 6 . The input end of...

Abstract

The invention discloses a full-automatic indoor environment control, obstacle avoidance and navigation type micro aerial vehicle. The micro aerial vehicle comprises an aerial vehicle body, a full-automatic control system, a power device group and a power supply group, wherein the power device group comprises four independent power devices, and each power device comprises a brushless motor, a propeller and an electronic governor; an environment identification sensor group comprises a two-dimensional laser scanning range finder, a miniature ultrasonic range finder, a foresight camera and a downward-looking camera; and a control module comprises a miniature computer processor, a miniature three-shaft gyroscope, a miniature three-shaft accelerometer and a miniature three-shaft magnetometer. The full-automatic indoor environment control, obstacle avoidance and navigation type micro aerial vehicle disclosed by the invention has an indoor full-automatic flight control function of automatically identifying a window to enter the room, and automatically avoiding collision with an indoor wall or obstacle without need of external radio control or satellite receiver navigation.

Description

[0001] technical field [0002] The invention belongs to a special aircraft, in particular to a miniature aircraft that does not need external radio control, can automatically control room entry, and can avoid obstacles and navigate completely autonomously. Background technique [0003] Current drones and micro air vehicles are inseparable from radio remote control and telemetry devices, and they do not yet have the function of autonomously identifying the environment and avoiding obstacles to fly. One direction for the future development of micro air vehicles is to develop from outdoor flight to autonomous flight for obstacle avoidance between buildings and indoor autonomous recognition of the environment to avoid collisions, that is, to develop a reconnaissance device for indoor autonomous flight. The current drones and MAVs already have certain automatic flight control capabilities, and they are usually inseparable from satellite navigation receivers (such as GPS or Beido...
