Automatic Landing System
• With a press of a button on the Android device, landing procedure begins
• Not Infringement– No predetermined point on the ground– Do not use imaging sensor or landing zone to help
land vehicle (using proximity sensor)

Waypoint Navigation
• US 7158877• Filed: November 25, 2003• Remote control of an unmanned aerial vehicle
from a control station by means of a wireless command link– Controlled in an autonomous mode– Controlled in a manual mode

Waypoint Navigation
• Autonomous Mode– Coordinate from Android application gets sent to
microcontroller, and quadcopter follows the path• Manual Mode– Quadcopter can be controlled through the
Android application• Infringement– Obtain license or pay royalty fee
