USING HANDHELD DEVICE TO CONTROL FLYING OBJECT
First Claim
1. A method of implementing remote-control of a flying object using a handheld device, the method comprising:
- activating the flying object to inspect status of the flying object when an operator uses one or two hands to hold the handheld device;
establishing a wireless communication link between the flying object and the handheld device in response to the activating;
detecting an operator input to a motion sensor module of the handheld device wherein the motion sensor module comprises a gyro-sensor and a g-sensor;
generating one or more piloting commands from the operator through moving and/or touching gestures for the handheld device in response to the detecting; and
executing one or more piloting actions based on the piloting commands for controlling the flying object from the handheld device;
wherein the one or more piloting actions are processed to maintain an orientation of the flying object, and the orientation is indicative of at least one of a roll, yaw and pitch angles, and translation thereof during flight;
wherein the gyro-sensor of the handheld device is provided to transmit its one or more motion signals in response to the operator input to the gyro-sensor of the motion sensor module so as to control a flight heading of the flying object around its yaw axis while the handheld device is rotated by the operator around its yaw axis; and
wherein the g-sensor of the handheld device is provided to transmit its one or more motion signals so as to control a flight translation of the flying object or the pitch and roll angles thereof, by tilting the handheld device around at least one of its pitch and roll axes.

Abstract
Method and system for remote control of a drone helicopter and RC plane using a handheld device is disclosed. Piloting commands and actions are performed using the handheld device, which includes a motion sensor module, with gyro-sensor and g-sensor for controlling roll, yaw and pitch of flying object under relative or absolute coordinate system. The gyro-sensor controls both heading and rotation of flying object in place around its yaw by rotating handheld device around its yaw axis; g-sensor controls pitch and roll by rotating handheld device around its pitch axis and roll axes. Upon determining free falling of flying object, throttle is thereby adjusted so as to land it safely. Flying object further has a camera, and video images are transferred wireless to be displayed on touch screen, and image zoom-in and zoom-out are provided via multi-touch of touch screen. RF and IR capability is included for wireless communication.
