Abstract

A homeostatic flying hovercraft preferably utilizes at least two pairs of counter-rotating ducted fans to generate lift like a hovercraft and utilizes a homeostatic hover control system to create a flying craft that is easily controlled. The homeostatic hover control system provides true homeostasis of the craft with a true fly-by-wire flight control and control-by-wire system control.

Claims

1. A method for operating a radio controlled (RC) flying hovercraft using an RC controller separate and remote from the RC flying hovercraft, the method comprising:

providing an RC flying hovercraft having a set of generally downwardly directed thrusters, each thruster including at least one blade driven by a battery powered motor to provide aerodynamic lift for the RC flying hovercraft under control of a control system in the RC flying hovercraft that is responsive to radio frequency (RF) communications from the RC controller;

causing an RF receiver in the control system in the RC flying hovercraft to receive communications from the RC controller, the communications including a desired orientation of the RC flying hovercraft, wherein the desired orientation communicated by the RC controller is determined based on a handheld structure housing a sensor system in the RC controller that senses a gravitational reference and at least a two dimensional, two-axis sensed orientation of the handheld structure with respect to said gravitational reference as a result of a user, remote from the RC flying hovercraft, selectively orienting the handheld structure;

causing a sensor system in the control system of the RC flying hovercraft to dynamically sense a gravitational reference for the RC flying hovercraft and determine an actual orientation of the RC flying hovercraft, the sensor system including at least a three-dimensional, three-axis sensor; and

causing the control system in the RC flying hovercraft to automatically and dynamically control a thrust produced by each of said thrusters to achieve and selectively maintain the actual orientation of the RC flying hovercraft in response to the desired orientation communicated to the RC flying hovercraft by the RC controller and the actual orientation determined by the sensor system in the RC flying hovercraft without any additional communications being required for the user to control moment-to-moment balance and stabilization of the RC flying hovercraft.

2. The method of claim 1, wherein the RF communications include two-way communications between the RC controller and the RC flying hovercraft and the method further comprises selectively communicating data transmissions in addition to control commands via the RF communications.

3. The method of claim 1, further comprising communicating video images from the RC flying hovercraft to the RC controller.

4. The method of claim 1, wherein the control system in the RC flying hovercraft includes software, the method further comprising receiving software updates by the RC controller from an Internet connection.

6. A method for operating a radio controlled (RC) drone that is remote from a hand-held controller, wherein the RC drone is a quadcopter multi-rotor flying craft having four electrically powered motors, each motor driving at least one blade configured to provide aerodynamic lift for the quadcopter multi-rotor flying craft, a battery system operably coupled to the motors, and a control system that includes control circuitry and a sensor system, the method comprising:

using a sensor system in the hand-held controller to sense a gravitational reference and a relative tilt of the hand-held controller with respect to the gravitational reference in response to a user selectively orienting the hand-held controller;

communicating control commands corresponding to a desired orientation of the RC drone based on the relative tilt of the hand-held controller by radio communications between the hand-held controller and the RC drone;
