Abstract

To provide a flying object including a lift generating member deployment device that makes it easier than before to automatically avoid collision with an obstacle. A flying object 30 includes an obstacle detecting unit 5 , a control unit 6 , a battery 7 , a storage unit 8 that stores information transmitted from the control unit 6 , a transmitting/receiving unit 9 that receives an operation signal from a controller 40 and transmits information regarding the flying object 30 to the controller 40 , and others. The obstacle detecting unit 5 is to detect the altitude of the flying object 30 and outputs an altitude detection signal, which represents the detected altitude information, to the control unit 6 . In addition, upon detecting an obstacle present within a predetermined distance, the obstacle detecting unit 5 outputs an obstacle detection signal to the control unit 6 , detects the distance between the flying object body 31 and the obstacle, and outputs a distance detection signal, which represents the detected distance information, to the control unit 6 . The control unit 6 determines whether or not to actuate left and right brake cord pulling devices 10 in accordance with the signal received from the obstacle detecting unit 5.

First claim

The invention claimed is:

1. A flying object comprising:
a flying object body;
a to-be-deployed object that is disposed in the flying object body and includes a lift generating member and a steering unit capable of steering the lift generating member after deployment via a connecting member connected to the lift generating member;
an obstacle detecting unit that is disposed in the flying object body and detects an obstacle present within a predetermined distance;
a wind direction detecting unit that is disposed in the flying object body and detects a wind direction; and
a control unit that receives, when the obstacle detecting unit detects an obstacle, an obstacle detection signal from the obstacle detecting unit, said control unit further receives from the wind direction detecting unit a wind direction signal including information regarding the wind direction;
wherein after the to-be-deployed object is deployed, the control unit operates the steering unit, on a basis of the obstacle detection signal and the wind direction signal, to perform at least either one of control to avoid collision with the obstacle or control to mitigate collision with the obstacle and to avoid tailwind.

2. The flying object according to claim 1 , further comprising:
a deployment device for the lift generating member, the deployment device being disposed in the flying object body, wherein the deployment device includes:
a containing unit that holds the lift generating member being in a closed state; and
an ejecting unit that ejects the lift generating member from the containing unit, and
after the deployment device is actuated, the control unit performs at least either one of control to avoid collision with the obstacle or control to mitigate collision with the obstacle.

3. The flying object according to claim 1 wherein the obstacle detecting unit includes at least one of a laser sensor, an ultrasonic sensor, a millimeter wave radar, a submillimeter wave radar, and a camera.
