4. http://my.fit.edu/senior_design/uav Overview – Sub-Teams Structures –Design airframe independently –All mounting points on the plane Electrical –Using off-the-shelf products –Autonomous flight or remote flight pattern recognition –Payload Image and data storage Ground-to-air communications Autonomous control unit Ideally air-to-ground communications also

5. http://my.fit.edu/senior_design/uav Team AURORA Aspires to create a smaller, more efficient and cost-effective product Alternative to current products Off-the-shelf electrical components –Cheaper product –Commercial applications possible

6. http://my.fit.edu/senior_design/uav Electrical Success The project will be considered successful if as long as all electrical components work, regardless of aircraft flight.

9. Requirements Create a UAV capable of performing realistic autonomous missions. The aircraft is to be launched and transition or continue to autonomous flight, navigate a specific course, use on board payload senors to locate and assess a series of man-made objects prior to returning to the launch point for landing. The take-off gross weight of the aircraft is not to exceed 55lbs. For safety purposes the aircraft wings must be able to handle a 2.5g load case without breaking. The aircraft must have a radio control fail safe that is automatically selected during the loss of signal or manually selected if required. Total mission time including time for image processing is 40 minutes. The mission is to be flown at an altitude above 50ft AGL and below 500ft AGL. The aircraft must be able to navigate using GPS and must be able to demonstrate dynamic control by changing airspeed, altitude, etc during the mission.

18. http://my.fit.edu/senior_design/uav Interface Specifications & Requirements Data –Raw Images taken from image –GPS location of each image –Heading and altitude of UAV for each image Image Manipulation –Images are overlaid together using GPS –Images are matched to digital landscape for elevation info –Output is converted to grayscale Image Processing –Given patterns are matched to locations on the landscape –Pattern matches are highlighed –GPS location is outputted

19. http://my.fit.edu/senior_design/uav Code for regulating power board Set-up circuit in PSpice and make sure voltages and currents are correct at each output terminal. Set up different test cases where it creates simulated spikes to see how the devices respond. Breadboard and test actual voltages and currents correspond to the theoretical values with generic loads before connecting equipment to prevent damage. Testing Procedures: Module 0

20. http://my.fit.edu/senior_design/uav Testing Procedures: Module 1 Code for taking and storing pictures Run the program that takes in GPS data and takes pictures saving the data and pictures to compact flash. Send in generic data where the GPS will connect serially and check if the USB output captures a picture. Finally check whether the data and picture was saved correctly. Test some outlying data to input as simulated GPS data and check to see if the code functions correctly.

21. http://my.fit.edu/senior_design/uav Testing Procedures: Module 2 Code for converting images Run the program that takes the data from the compact flash. Use generic input to test whether the system is successful converting the image. Once the software has completed this process, a test should be conducted to determine whether the converted was saved correctly into memory.

22. http://my.fit.edu/senior_design/uav Testing Procedures: Module 3 Code for image recognition Run the program which uses the previously converted image to look for specified objects. Using the sample input, test whether the system is able to locate for the objects. Lastly, check to see if the information on the recognized objects is stored correctly into memory.

23. http://my.fit.edu/senior_design/uav Risks & Solutions - Technical Power Board Development may take more time than anticipated –Preliminary power board layout is complete –Currently designing schematics for power board –Determining the correct value for the components for the power board are taking longer than expected –Calculations are not giving the desired output –Solution:Continue testing power board circuit and seek professional assistance Software Development may take more time than anticipated –Currently writing algorithms for: Module 0: Regulating Voltage Module 1: Image Restoration from Snapshots Module 2: Image Conversion Module 3: Image Recognition –Need assistance for MatLab coding in Labview –Solution:Seek professional assistance

24. http://my.fit.edu/senior_design/uav Risks & Solutions - Schedule Time delay due to power board and software development taking more time than anticipated Time delay in ordering the necessary parts Possibility of not receiving parts on time to build and test prototype during allotted time period Time delay in ordering new parts, if necessary –Solution: Resolve technical risks immediately to avoid future time delays readjust schedule and overestimate possible man hours in order to consider future time delays

25. http://my.fit.edu/senior_design/uav Reliability and Maintainability Measures of Reliability: –Mean Time Between Failures (MTBF) In terms of flight hours –Failure Rate Failure over a certain time period

26. http://my.fit.edu/senior_design/uav Reliability and Maintainability Measures of Maintainability: –Mean Time to Repair Average number of repair times –Maintenance Man-hours per flight hour –Maintenance crew size Average number of people required to accomplish the task Factors which influence reliability: Proximity to ground –Affects interfacing with electronics at the base station
