[Paparazzi-devel] hb_autopilot

[Prof. Dr.-Ing. Heinrich Warmers]

Dear paparazzi  Users,
or hardware documentation, as well as the software to fly  quadrocopters 
are online.

The hb_autopilot has the following advantages:
2 separate PCBs,
imu pcb:  up to 2 accelerators, 3 rate sensors (Types possible:  ADX610 
$50, LIS $14 , Melexsis $30) pressure sensor, difference  pressure 
sensor, temperature sensor low cost magnet sensor $17
since the communication is made only with SPI and 3 CS lines this  IMU 
can work with all micocontrollers pcbs: tiny 13, tiny 22 hb- autopilot, 
ollimex
mcu pcb: all communications connections free 2 spi, 2 i2c 2 uart,  jtag 
interface, analogue connectors, power switches, 10 servo  outputs 
(normal servo connectors), reset connection usb connection  analogue 
interfaces This pcb is  paparazzi compatible and can  work with the 
booz2 and HB_IMU was well with the ir-sensors. I want  to port the booz2 
software also on the hb_autopilot but this will  need same time.

If you want to look to the hard and software please download on 
http://savannah.gnu.org/submissions_uploads/  the file work_tar.gz
with this file you get the gpl software and the gpl hardware (eagle  
files).

Currently we fly wiht kalman filters please look :

We have also made a quadcopters with a single imu pcb (one layer)  with 
the sparkefuns rate sensors and a lis accelerations sensor  connected to 
the tiny 13.
