  12. AGSE Containment • Spring-loaded doors will allow the payload to pass through the airframe • A containment device will catch the payload • The containment area will be ejected at 1000 ft. for recovery

  13. AGSE Containment

  14. AGSE Containment

  15. Plan For Safety Verification • Team safety briefings • Consultation of mentor and faculty experts • Verify design with calculations and RockSim analysis • Identify potential hazards for construction and launch • Follow launch checklists and guidelines • NAR High Power Rocket Safety Code • Comply with federal, state, and local laws

  16. Risk Assessment Strategy

  17. AGSE Subsystem Overview • Body • Camera Subsystem • Laser Ranging subsystem • Payload Retrieval subsystem • Main Computer • Power subsystem

  18. AGSE Body Subsystem To provide support and mobility for all AGSE subsystems Components • Chassis • Rocker Bogie Suspension • 6 Wheel Servo Motor Drive

  19. AGSE Camera Subsystem Use image analysis to determine the necessary orientation of the AGSE with respect to the payload or hazards. Components • Pixy CamCMU5 • Pan-Tilt Head • Arduino Uno R3 • Adafruit Data Logging Shield • 8gb SD Card

  20. AGSE Laser Ranging Subsystem Use the emission and detection of laser pulses to calculate the distance from the AGSE to the payload or the launch vehicle Components • Lightware SF02/F Laser Ranging Module • Polulu 200 Step Bipolar Stepper Motor • Polulu A4988 Stepper Motor Driver • Arduino Uno R3

  21. AGSE Payload Retrieval Subsystem Physically obtain and transport the payload from its location to the launch vehicles payload containment bay. Components • Lynxmotion AL5D Robotic Arm • OV7670 Camera Module • Flexiforce Pressure Sensor • Arduino Uno R3
