Transmitter
The transmitter offers a reliable wireless link between the GCS and Elios.
Full HD Optical Camera
Elios is equipped with a Full HD optical camera. The Standard Definition (480p) live video feed is
transmitted to the pilot, and the FHD (1080p) footage is recorded on the SD cards. The camera is
mounted on a servo motor allowing it to tilt up or down.
Do not tilt the camera by hand, as this may damage the servo
motor.
The full HD Optical Camera has three modes:
-
Automatic mode: The user sets the Exposure Value (EV) whereas the camera automatically
sets the ISO and the exposure time to keep the EV constant. The EV corresponds to the overall
brightness of the image.
-
Manual low ISO: The user sets the Exposure time whilst the ISO is set to 50.
-
Manual high ISO: The user sets the Exposure time whilst the ISO is set to 1600.
from
which the user can later export frames. The video recording starts when the robot is armed and stops
automatically when the robot is disarmed.
Thermal Camera
The FLIR LEPTON thermal camera is coaxially mounted next to the video camera and can also be tilted
up and down. The footage of the thermal camera is automatically saved in the LOG SD card and can
be reviewed using Flyability Inspector. The pilot can also switch to the video feed of the thermal
camera during flight.
Motors and Propellers
Four propellers create the thrust required to fly. Propellers on the arms annotated with an R are
spinning counter-clockwise whereas the other two others are spinning clockwise. The R propellers are
mounted on the R arms. The non-R propellers are mounted on the non-R arms. This is important when
replacing propellers.
Camera SD Card
The Camera SD Card records the full HD optical video feed whilst Elios is flying. Please only use the
provided SD card, as this has been tested to ensure it meets write speed requirements.
Log SD Card
The Log SD Card records the thermal video feed as well as plenty of telemetry data. The telemetry will
be useful for you to analyze your flight using Flyability Inspector software. Furthermore, it will help the
Flyability team run diagnostic tests in case of issues with your system. Please only use the provided SD
card, as this has been tested to ensure it meets write speed requirements.
Battery
A removable LiPo battery powers the aircraft, providing up to 10 minutes of flight time.
Onboard lighting
A powerful array of white LEDs offers bright lighting on the front, top, and bottom of the aircraft. It
helps operators navigate and gather high-value footage in dark environments, the intensity can be
adjusted in flight via the Ground Control Station.
Guiding LED
To help the pilot during Line of Sight (LOS) operations, two colored LEDs are installed to help improve
orientation awareness. The Red LED is located on the left and the Green LED on the right side of the
aircraft.
If the LEDs are blinking alternatively, it means Elios is waiting to connect to the ground control unit.
If the LEDs are blinking rapidly synchronously, Elios is performing a power-on self-test.
