Abstract
Methods and apparatus are provided for launching and landing unmanned aerial vehicles (UAVs) including multi-rotor aircrafts. The methods and apparatus disclosed herein utilize positional change of the UAV, visual signal, or other means to effect the launch or landing. The methods and apparatus disclosed herein are user friendly, particularly to amateur UAV users lacking practice of operating a UAV.
Claims20
A method for launching an unmanned aerial vehicle (UAV) comprising one or more rotor blades into flight, the method comprising:
- detecting, via one or more sensors on-board the UAV, (1) a release of the UAV by a mechanical or human hand, and (2) a positional change of the UAV during the release;
- and
- processing, with aid of one or more processors on-board the UAV, the detected positional change and the detected release to autonomously generate without human intervention one or more command signals to effect a lift and/or thrust through rotation of the one or more rotor blades, thereby causing the UAV to be autonomously launched into flight after the release.
A system for launching an unmanned aerial vehicle (UAV) comprising one or more rotor blades into flight, the system comprising:
- one or more sensors on-board the UAV, configured to detect (1) a release of a grip on the UAV, and (2) a positional change of the UA during the release;
- and
- one or more processors on-board the UAV configured to process the detected positional change and the release of the grip to autonomously generate without human intervention an actuation signal, wherein the actuation signal is configured to direct the one or more rotor blades of the UAV to generate a lift and/or thrust, thereby causing the UAV to be autonomously launched into flight after the release.
A method for bringing an unmanned aerial vehicle (UAV) comprising one or more rotor blades to a complete stop, the method comprising:
- detecting, via one or more sensors on-board the UAV, (1) a positional change of the UAV and (2) a contact on the UAV with an external surface while the one or more rotor blades are in motion;
- and
- processing, with aid of one or more processors on-board the UAV, the detected positional change and the contact with the external surface, to autonomously generate without human intervention a deceleration signal to bring the one or more rotor blades of the UAV to a complete stop.
