ASCTEC AUTOPILOT
AscTec AutoPilot
The AscTec AutoPilot is a precise and mul-
tifunctional research tool mounted on all
AscTec UAVs. This flight control unit contains
all necessary sensors to function as an IMU,
it also has two onboard ARM7 microproces-
sors and various communication interfaces.
There are several strategies on how the
AscTec Auto Pilo t can be uti lize d for your
research projects. It can directly interpret
the R/C data sent by the pilot and the serial
data sent from the ground PC. For automatic
missions, you can program and upload your
own control algorithms directly onto the
High Level processor of the UAV.
If more processing power is required or
additional sensors, like cameras or laser
scanners need to be connected, an ad-
ditional onboard processor is installed. Its
high performance and fast communication
enable you to handle large amounts of data
onboard. An optional WLAN module can be
integrated to exchange this data between the
additional processor and a ground PC. All
gathered data can be used for your control
algorithms and the calculated commands
can then be sent to the AscTec AutoPilot.

ASCTEC AUTOPILOT
Low Level processor
The Low Level (LL) processor handles sensor
data processing, data fusion as well as our fast
and stable attitude control algorithm with an
update rate of 1000 Hz. It also processes the
position control algorithm, using the onboard
magnetometer and GPS module as additional
sensor inputs. All AscTec UAVs can be oper-
ated by the pilot via a remote control in three
different flight modes:
GPS Mode (attitude-, height- and position-
control activated)
Height Mode (attitude- and height-control
activated)
Manual Mode (attitude-cont rol activated)
All AscTec UAVs have an emergency mode
which is automatically activated if the data link
between the UAV and the R/C of the safety
pilot is lost (range > 1 km). You can choose
between several emergency options depend-
ing on your mission.
Sensor data can be retrieved from the
LL processor via a serial interface using a
predefined serial protocol. Furthermore, the
serial interface can be used to send attitude
commands (pitch angle, roll angle, yaw rate
and thrust) or even waypoint commands to
the vehicle depending on the flight mode.
Due to the size of the data structures, update
rates of up to 15 Hz can be accomplished via
a wireless serial link (XBee, range > 1 km).
Higher update rates of up to 100 Hz can be
achieved using a serial cable connection.
Available data packages
Raw IMU data, calculated IMU data, R/C
data and GPS data can be polled from the
AscTec AutoPilot.
High Level processor
The basic concept of the AscTec AutoPilot is
to offer easy programmability, and to provide a
safety net while testing your own control algo-
rithms. Therefore you can flash the High Level
(HL) processor with your own algorithm and
let it control the flight system. To recover from
critical flight situations during your test flights,
the pilot can always switch back to the well
proven control algorithms on the LL processor
as a safety backup.
The two microprocessors communicate with
an extremely fast rate of 1000 Hz, hence all
sensor data is available to the HL processor
as well. Control commands can be sent back
to the LL processor at the same frequency,
for example the: rotational speed commands
for each individual motor, pitch/roll/yaw/thrust
commands, attitude commands or waypoint
commands.
The HL processor offers UART, SPI and IC
interfaces as well as simple port I/Os to con-
nect your own devices like additional sensors,
servo motors or extension boards. Also custom
payloads, like wireless cameras, can be powered
by a 5 V or 12 V supply of the AscTec AutoPilot.

ASCTEC SDK
AscTec HL SDK
To program the HL processor, we provide our
free software development kit (SDK).
The AscTec HL SDK 2.0 is a C-code framework
in an Eclipse environment with cross-compiler
and debugger. You can use the AscTec HL
SDK 2.0 to program your own algorithms,
sensor interfaces and communication proto-
cols in C-Code and upload your code to the
HL processor. In combination with our AscTec
JTAG you can debug your code online.
New in SDK 2.0
Several new code examples help the first time
user understand the idea and possibilities of
the AscTec SDK 2.0. Two additional control
modes were added, one lets you command
each single motor individually, and the other lets
you send waypoint commands directly from the
HL processor. For a better overview all readable
sensor data are saved in a single data struc-
ture. Together with an updated motor controller
firmware, the motor feedback is now available.
AscTec Communication Interface (ACI )
The AscTec Communication Interface (ACI)
is designed to offer an easy and fast com-
munication between a remote software and
the high level processor.
It lets you request variables, send commands
and set parameters on your AscTec UAV.

SIMULINK TOOLKIT
AscTec Simulink Toolkit
Matlab Simulink, the well-known system
modeling software, can now be used to
program the HL processor of our AscTec
UAVs. Therefore we offer the AscTec Simulink
Toolkit which works in cooperation with the
AscTec HL SDK 2.0. The toolki t i ncludes a
predefined onboard model to integrate your
own Simulink based control algorithms. This
model can be automatically translated into
C-code for the AscTec HL SDK 2.0. A simple
attitude control example is already imple-
mented to show you the possibilities offered
by the toolkit.
There are several predefined parameter-,
control- and debug blocks available which
can be integrated into your own control al-
gorithms. The Simulink toolkit offers a UART
communication model to monitor these debug
channels (with up to 50 Hz), as well as to
send individual control commands, both via
an XBee modem on the serial port of the HL
processor. Furthermore, you can easily update
your parameters or store them permanently
by running an M-file.

THE ASCTEC FIREFLYSafety and Ease of handling
AscTec Firefly
The AscTec Firefly is the latest and most
advanced UAV in the AscTec fleet. It was
engineered for highest security and easy
handling, hence its perfect for your automatic
flight experiments.
Besides the small nonhazardous propellers
and low take-off weight, it comes with a pat-
ented redundant propulsion system, which
allows a controlled flight with only 5 rotors.
Selectable emergency modes allow difficult
flight missions.
The modular structure enables fast compo-
nent exchanges in case of a crash or modi-
fication during integration and testing. The
frame in frame concept was designed to
decouple the fixed connection of payload
and IMU from the vibration inducing motors.
This concept raises the quality of the sen-
sor and camera data and avoids dynamic
misalignments. Optional propeller types tune
the AscTec Firefly to either maximum security
or maximum performance.
