The Explorer is a rotorcraft.
It is used to test :

  • control loops such as PID and INDI
  • simultaneous datalinks such as Xbee and Wifibroadcast
  • vision algorithm

The Explorer frame is 3Dprinted Explorer/3DPrinted

The aircraft flies an Apogee or a Tawaki autopilot board Explorer/PPRZ.

The RaspberryPi provides:
- a camera link
- an additional communication link
- an easy way to run computation tasks

There are two RaspberryPi :
- on board, as a companion board to the autopilot
- on ground, as an interface to the companion board

The RPI Zero and RPI 3B can be used in this aircraft as they provided at least one UART and one USB
Explorer/RaspberryPi

The equipments connected to the autopilot board are :

The equipments connected to the companion board are :

  • Camera
  • External wifi
