No more restrictions as from now; with a few simple clicks you can run Paparazzi on the Bebop and have full autonomous flight and much more!
What you need:
- A bebop drone (1 or 2) with the newest firmware
- A joystick (example: http://www.hobbyking.com/hobbyking/store/__20951__Hobbyking_6CH_RC_Flight_Simulator_System_Mode_2_.html
- A laptop with Ubuntu, or a virtual box. You can download one here: https://mega.nz/#!1JpTiTjS!GdAHpa-_FAQAFPNypp3a3Up0B0yo1kYLXi3YLMXSAoo}. The password for this virtual box is "mavlabcourse" (the same as the username).
Steps you will need to follow:
- Install Paparazzi: http://wiki.paparazziuav.org/wiki/Installation . This is already done on the provided virtual box
- Start paparazzi with the default configuration
- Power up your Bebop.
- If you have a Bebop 2 or a Bebop 1 with firmware v3.2.0 or higher press the on/off button four times in short fast after powerup
- Make a Wifi connection with your PC and the Bebop
- In the Paparazzi center choose "Bebop" Or "Bebop2" in the airframe dropdown menu
- Press "Upload"
- Select Flight UDP 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. Useful things to watch are:
- The video series here: https://www.youtube.com/watch?v=eojAPZvT1Ck . Although it is made for the ARDrone the steps are very similar for the bebop drone.
- This site has several documents on how to program something for your drone: http://mavlabcourse.tk/ . Although these documents assume you have an indoor flight area, you can also fly outside with the internal GPS of the Bebop.

The Bebop has 4 Brushless motors, which are controlled by the cypress chip on I2C-1. This Cypress chip contains custom made firmware(BLDC) by Parrot, which can be automatically updated using a bootloader in the ESC part of the mainboard. The firmware from Parrot contains a nice closed loop RPM control, which is automatically tuned inside the factory. Since version 2 Parrot changed the order and rotation direction of the motors.
For more information about how to communicate with the BLDC look at Bebop/BLDC. Or take a look at the "bebop" actuator inside the
The original programs on the Bebop
- /usr/bin/dragon-prog Main program that controls the drone
- /bin/watchdog.sh Checks if Dragon is still running and reboots dragon-prog if it somehow would not be running anymore
- 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.
the past you could also crosscompile with Sourcery CodeBench Lite 2012.03-57 for ARM GNU/Linux from
Greedy Mentor Graphics, previously called codesourcery. However the open'ness there is nowhere to be found anymore, so we'll say "No thanks" to Codesourcery ,now Greedy Mentor"
but if you insist , feel free restricted.
Tips & Tricks
Make sure the video_rtp_stream.xml module enabled in the airframe. Receive a video stream with e.g. avplay, vlc or a python app:
$ avplay -loglevel quiet -max_delay 50 -fflags nobuffer rtp://192.168.42.1:5000 $ vlc ~/paparazzi/var/sdp_tmp/192.168.42.1/stream.sdp $ ~/paparazzi/sw/tools/rtp_viewer/rtp_viewer.py
You can reset the Parrot Bebop Drone to factory settings. You will loose all your photos and movies recorded on your Bebop. To do this you need to press and hold the power button for 10 seconds. The LED will blink green and orange for a while, then green and the drone will shutdown.
Theoretically is is not important which firmware you use for Paparazzi to fly. But with the latest firware we get better Video imagery. So if you can.. use the latest firmware.
The Paparazzi volunteers test flew the Bebop with Firmware v1.98.11 and v2.0.57, v3.0, v3.2, v3.3, v3.9, v4.0.3
Note that under v4.0.3 the Front cam doesn't work (yet..)
The v3.3.0 is the latest firmware version know as of 20170215 for Bebop 1. For bebop 2 Latest know is v3.9 final and v4.0.3 Beta If even newer firmware is available please report any (if any) issues found related to the firmware on e.g. the mailinglist.
Using the MicroUSB for serial data
The Bebop has this tiny USB connector just above the power button. This USB connector can also be used with help of a USB to Serial FTDI conversion board. To use the driver in current firmware OTG serving should be off. More information, photos, connection examples, sourcode and real life example of how to use this port.
