1. Collision Avoidance for Unmanned Aircraft Systems (UAS)

2. Auburn Objective (2008) “fly safely and efficiently, in a limited space, a fleet of autonomous UAVs on a cooperative mission with terrestrial vehicles. ” Challenging Constraints –UAVs must fly at constant speed –UAVs must fly at the same altitude

3. Completed Tasks Since August 2008 Started with an amateur platform (DIY Drone Easy Star) Summer 2010: Auburn adds a digital data link based on Zigbee –Multi hop mesh network (UAVs can be used as relays/routers) –On fly waypoints updates

4. Completed Tasks Since August 2008 (Con’t) Summer 2011: – Integrated software architecture that allows the evaluation of collisions avoidance (CA) algorithms using simultaneously a mix of real and virtual UAVs –Implemented and evaluated 3 collision avoidance algorthms (different families) Summer 2012 –Designed, implemented. And evaluated one new collision avoidance algorithm –Implemented 4 additional CA algorithms
