Private Ground Station:

Public Ground Station:

  • TCP/IP command & status link.
  • Manual flight control.
  • Autonomous flight control.
  • Aircraft webcam video viewer.
  • Aircraft and flight statistics viewer.

SoftwareImplementation

Central Processing Unit:

Sensor & Servo Processing Unit:

  • TCP/IP server for command & status link.
  • TCP/IP server for webcam link.
  • Main flight control system.
  • Serial interface to SPU.
  • USB interface to webcam.
  • Command & status decoding & encoding.
  • Sensor data reporting and retrieval.
  • Management of sensor control (power, sensitivity, etc.).
  • Generation of pulse width modulation (PWM) for servo positioning.

Risks

Prevention

Crash

Progressive build process. Testing, testing, testing!

Loss of link and high latency

Design aircraft software for autonomous flight. Use fail safes (timed hover and land) for complete link loss.

Interface to helicopter is only theoretically known.

Get the hardware figured out early. Testing the interface thoroughly before flight.

Not 100% sure we’ll get the helicopter and stabilization kit

Beg, borrow, and steal!
