Originally the Bebop from Parrot is a Wifi controlled flying quadrotor, designed to be controlled with an Android or iOS device. Not any more: With a few simple clicks you can run Paparazzi on the Bebop and have full autonomous flight and much more!
- Make sure you have the latest release version of Paparazzi installed.
- Power up your Bebop.
- Make a Wifi connection with your PC and the Bebop
- In the Paparazzi center choose "Bebop" in the airframe dropdown menu
- Press "Upload"
- Select the Bebop or ARdrone2 Flight in the session menu
- Press execute
Voila, you will get telemetry from the Bebop. Now it is up to you how and where to fly.

The Bebop has 4 Brushless motors, which are controlled by the cypress chip on I2C-1. This Cypress chip contains costum made firmware(BLDC) from Parrot, which can be automatically updated using a bootloader. The firmware from Parrot contains a very nice closed loop RPM control, which is automatically tuned inside the factory.
For more information about how to communicate with the BLDC look at Bebop/BLDC. Or take a look at the "bebop" actuator inside the
- /usr/bin/dragon-prog Main program that controls the drone
- /bin/watchdog.sh Checks if Dragon is still running and reboots dragon
- BLDC_Test_Bench Controls the Brushless Motor Controllers for testing and playing sounds etc.
- bcmwl Everything with wifi
- diagnostic Outputs sensor diagnostic
- mk3_camera_eeprom Reads the front camera EEPROM
- config_mt9v117 Configure the bottom camera
For the Bebop you need to use a recent version GNU gcc-arm-linux-gnueabi (Ubuntu/Linaro 4.7.4-2ubuntu1) 4.7.4 provided with Ubuntu since 14.04 LTS.
If it doesn't work with your GCC/Linaro version, you can also try the Sourcery CodeBench Lite 2012.03-57 for ARM GNU/Linux from Mentor Graphics (previously codesourcery). This cross compiler is available here: Sourcery CodeBench Lite 2012.03-57 for ARM GNU/Linux. Please install this crosscompiler in the /usr/local/codesourcery/ directory of your computer, to make sure paparazzi is able to find the cross compiler.
Load the video_rtp_stream.xml module. Receive the video stream with e.g. avplay:
$ avplay -loglevel quiet -max_delay 50 -fflags nobuffer rtp://192.168.42.1:5000
