.One ground station communicating with multiple
aircraft
.One python script to send commands
.Use the A* algorithm to determine a new path to
avoid a possible collision PROJECT REVIEW Future Work PROPOSED CHANGES AERO AND STRUCTURES
.Bolt nose cone for friction failure safety net
.Quick connect power plugs between sections
.Side clips protrude from bottom
.Landing Gear Sections
.C clamp pin design PROPOSED CHANGES ELECTRICAL . Modifying vehicles to be compatible with autonomous flight . Including the collision avoidance software in the programming of the vehicles . Figure a better power solution for kestrel . Replacing older electronic components used in the Motor Glider and X8 PROPOSED CHANGES SOFTWARE
. Each plane run its own script in the GSC
. Remove the ground control station and each plane
operate independently
. Different algorithm for avoidance PROJECT REVIEW Encountered Risks DESIGN RISKS AERO AND STRUCTURES
.New Fuselage Design .Modular design may not provide sufficient strength .Connection points will not properly secure sections DESIGN RISKS ELECTRICAL
. Kestrel . Not enough power to hover . Control issues with vertical to horizontal flight
. X8/Motor Glider . Control System Failure . Autonomous failure
Side view of Kestrel DESIGN RISKS
• Risks SOFTWARE • Program not working perfectly in the air, or not fast enough would result in a collision • Program not being feasible with Mission Planner’s constraints • System not being useful for future work because it is non-transferrable to an active collision avoidance system.
