  2. 2005 AUVSI Student UAV Competition Pax River Competition • 3rd Annual Association of Unmanned Vehicle Systems International Student UAV Competition • Hosted by the U.S. Navy Program Executive Office for Strike Weapons and Unmanned Aviation • June 30th – July 3rd at Webster Field (NAS Pax River) BIG BLUE 3 Design Review University of Kentucky

  3. 2003 and 2004 Competitions • Competition goals are to encourage undergraduate engineers to develop platforms capable of performing realistic autonomous operations and demonstrate low-cost innovative UAV designs BIG BLUE 3 Design Review University of Kentucky

  4. Competition Details • Teams are required to takeoff (manual or autonomous), fly specified waypoints, locate and identify targets on the ground, and return for landing within the allotted time • Mission criteria includes autonomous flight, GPS waypoint navigation, target reconnaissance, ability to adjust to changing mission requirements BIG BLUE 3 Design Review University of Kentucky

  5. Competition Details (continued) • Planes will have to fly within the altitudes of 50 and 500 feet • Mission will be carried out within a 2 mile range • Targets to recognize • 4x4 wooden targets of varying color • 10x10 concrete targets with lines • Teams will be given extra points for high resolution imagery BIG BLUE 3 Design Review University of Kentucky

  6. 2005 Competition • 15 teams will be entered in this year’s competition (30 schools have expressed interest) • Each team will consist of a team captain and nine other students • Only one grad student may accompany the team, and faculty advisors may only serve as safety pilots • Prizes: 1st - $5,000 2nd - $3,500 3rd - $1,500 BIG BLUE 3 Design Review University of Kentucky

  7. Requirements Develop a Control System and Aircraft • Autonomous Flight Controller • Communication Link • Image Analysis • Hardware • Airframe and Propulsion System BIG BLUE 3 Design Review University of Kentucky

  9. Pax River Mission Control Mission Control Flight Control Command Interpreter Network Interface Imaging Network Interface Network Interface Network Interface Telemetry/ Flight Stations Communication BIG BLUE 3 Design Review University of Kentucky

  10. Networking Requirements • Develop an embedded high speed interconnection network • Support various standard serial formats (I2C, SPI, RS232) • Provide a robust communication channel for high noise environments • Modular network architecture • Standard PCB design for mass production • Route power to other modules BIG BLUE 3 Design Review University of Kentucky

  11. Network Fabric of Choice • CAN 2.0b • Is a high-integrity serial data communications bus for real time applications • Operates at data rates up to 1 Megabits per second • Has excellent error detection and confinement capabilities • Was originally developed by Bosch for use in cars • Is now being used in many other industrial automation and control applications • Additional Features • Pre-existing CAN aerospace protocol, which has been standardized by NASA as a next generation aviation bus BIG BLUE 3 Design Review University of Kentucky

  12. Flight Control -MicroPilot MP2028 MP2028g commercial “full featured” autopilot Features • Altitude hold, Airspeed hold • GPS waypoint Navigation • 1000 programmable waypoints • Capable of autonomous launch/landing • User programmable feedback gains and flight parameters (even during flight) • Data log capability • Supports user modification of autopilot internals with XTENDER system BIG BLUE 3 Design Review University of Kentucky

  13. BB3 Pax River - Image Processing Analog frame grabber module • Enables the Matrox Odyssey Xpro to capture data all types of video sources. • Four completely independent high frequency and high fidelity video capture inputs. Pattern Matching Algorithm • A search algorithm whereby input frame patterns are acquired and matches are sought in a search database which consists of the various aviation directions. • Matrox Imaging library’s pattern matching algorithm is used to achieve this functionality. BIG BLUE 3 Design Review University of Kentucky

  14. Ground Station • Primary Computer • Visual C++ and ActiveX Library • Read and parse telemetry from the serial port • Use telemetry to drive instruments • Target Recognition • GPS Waypoint Programming • Servos controlled by joystick • Secondary Computer • Same as primary but without control BIG BLUE 3 Design Review University of Kentucky
