  1. CAMERA CONTROL • Robert Koontz • Shadab Ambat • Jeannette Djigbenou • Siva Jeganathan • Justin Raney • Matt Smith UK Aerial Robotics Team University of Kentucky

  2. Objectives Design camera subsystem to store photos and record position information. This will include: • Capturing clear images of the flight especially over the target area. • Allocating memory for the images and position information. • Ability to read/write CAN packets. • Capability to stream video back to ground station. UK Aerial Robotics Team University of Kentucky

  3. Requirements • Storage for images and position data • Estimated mission time of 40 minutes • Image space needed: • 20pics/min =>800pics@~450KB => ~360MB • 40pics/min =>1600pics@~450KB => ~720MB • Flash space needed: 64KB Data/Program Flash • 6 pieces of info @ 8bytes each @800 pics =>~6.4KB • 6 pieces of info @ 8bytes each @1600 pics =>~12.8KB • OS + subroutines uses 24.6KB now • Estimated altitude of 250ft avg during flight • View of 500ft Horizontal @ 2048pixels => 4pixels/ft • View of 288ft Vertical @ 1536pixels => 5.3ixels/ft UK Aerial Robotics Team University of Kentucky

  4. Design • Using Aiptek IS-DV digital camcorder • Fixed lens camera • Digital zooming • NTSC video out • 3MPixels ~ 2048 x 1536 Pixels ~ 450KB/image • Built-in SD Card Slot (Max. 1 GB) • TXA5-Rcb 1W-70 cm transmitter @ 426.25MHz UK Aerial Robotics Team University of Kentucky

  5. System Diagram ATV Plane Link 8051/040 Aiptek cam +3.7 V Transmitter +12 V +9 V Can Bus CH3,4 Baseband Video TVC-4G Down Converter RF TV/VCR Signal Processing Computer ATV Ground Link +120 VAC Power converter +12 V Car Battery UK Aerial Robotics Team University of Kentucky

  6. Budget • Camera • Power in: NP60 Li-Ion Rechargeable Battery 3.7V @ 350mA • Size: 4.0" x 1.8" x 2.4" • $120 refurbished and $10 for mounting hardware • ATV • Size: 1.8 x 3.5 in. Weight: 2 oz. • Power Out: 1.5 Wp.e.p. to 100 mW. • Power in: 350 mA @ 12 V @ 1W UK Aerial Robotics Team University of Kentucky

  7. Risks • Interference between ATV TX and Piccolo TX • Stress relief on PCB connections • A camera hiccup would throw off index for stored position information UK Aerial Robotics Team University of Kentucky

  8. Status • Need to do EMC test with transmitters • Currently writing subroutines to consume CAN packets, read/write memory, and produce CAN packets for debug • Currently inserting functional code into OS and debugging UK Aerial Robotics Team University of Kentucky
