Overview
Booz is an extension of Paparazzi to VTOLs. At the current stage of the project, the system provides attitude stabilization, vertical and horizontal guidance and automatic navigation. It is able to use Paparazzi flight plans and uses Paparazzi telemetry and datalink, which means all the Paparazzi ground segment applications are available( plotter, settings, gcs, etc...)
The current avionics consist of 3 boards
- The main board, comprising power supply, a LPC2148 and a barometer.
- The IMU board, comprising gyroscopes, accelerometers, magnetometers and a 16-bit ADC.
- The GPS board, using a LEA-5H by ublox.
Additional Booz boards:
- The "power" board.
It flies on a variety of Quad-rotor platforms
and less common vehicles
Simulator
Paparazzi features the advanced NPS simulator which can serve many purposes, from learning how to operate a vehicle to evaluating control or estimation algorithms.
Hardware
Motor controllers
Booz is able to handle a number of quadrotor specific brushless motor controllers.

Airframes
One nice thing about quadrotors is that the mechanics being extremely simple, they can be build with very few tools. Booz mounting holes are compatible with popular of the shelf frames.

Purchasing Hardware
There are now vendors offering Booz hardware, Please see the Get Hardware page for details.
Hardware Test
Booz comes with a number of simple test programs that you can use to validate a newly assembled board or learn how booz code works in case you want to extend it.

Sensors Calibration
All the sensors needs to be calibrated in order to provide useful informations. The calibration process needs to be performed after the assembly of the vehicle is complete.
- Note: The barometer on the Booz Main board is designed to work between -300 to 928 meters MSL. In this range it will create a zero offset, and then give 10cm resolution for 100 meters of altitude. BEWARE! if you fly above 100m the ADC will saturate. In addition, if you are someplace that is above 928 meters MSL the baro will not calibrate on boot, and will not output values. If you look at the RAW messages you will see that the BARO_RAW message reads 0 for both values. To fix the latter issue, the Value of R20 on the Main board can be changed to change the range. An example: If R20 is changes from a 560ohm to a 100ohm resistor, the new measurable range would be from -300 to 1800 meters. Because this changes the gain on the sensor it will also change the amount of altitude you can read from the ADC. For this case we reduce the amount to ~90 meters.

GCS notes
- If you set your ground modems for an interface rate different than 9600bps you need to add a flag to the "link" program on startup. In GCS if you use "Execute" you will see "link" is the first. You can click stop, then modify the command line by clicking in the text area. Add the -s flag with the baud rate you use. In my case 57600. So I use: -s 57600. Then click "Redo" and link will be restarted with the new flag and value (and you will start seeing messages and GCS wil populate). So you don't have to repeat this each time do "Save Session" and this will save the changes.
