Abstract: A precision landing system is described for an unmanned aerial vehicle (UAV). The system may include one or more anchors configured for placement in proximity to a landing zone, a tag configured for securement to the UAV where the tag wirelessly communicates with at least three or more of the anchors. A controller may be configured to fly the UAV towards a centerline axis defined through a first airspace zone at a first altitude above the landing zone while descending towards the first altitude and then fly the UAV towards the centerline axis defined through a second airspace zone at a second altitude which is below the first altitude while descending towards the second altitude, and finally to fly the UAV towards the centerline axis defined through a third airspace zone at a third altitude which is below the second altitude while descending towards the landing zone.

Abstract: Integration between unmanned aerial system and unmanned ground robotic vehicle are disclosed herein. One variation of a robotic system may generally comprise an unmanned aerial vehicle (UAV), an unmanned ground vehicle (UGV), and a base station configured to receive the UAV and replace a spent power supply cartridge from the UAV and further having a charging mechanism configured to wirelessly transfer power to the UGV when the UGV is positioned in proximity to the charging pad.

Abstract: An automated alert system using unmanned aerial vehicles is described where the system is configured to monitor a selected area via one or more sensors configured to monitor the selected area for an anomaly. A processor in communication with the one or more sensors may be programmed to create or alter a flight path of an unmanned aerial vehicle upon receiving an alert from the one or more sensors for investigating or verifying the anomaly.
