SNT SPIDER AUTONOMOUS 2.0 Operation Manual page 24

On the cover of the machine there are domes with
46
radio and navigation components:
1
LTE antenna, which provides communication with the server (monitoring
and diagnostic data, firmware updates, transmission of correction data).
2
It contains a UHF radio receiver that receives correction data. A red LED
indicates the reception of correction data over UHF.
3
GNSS receiver.
4
RC dome — Bluetooth communicator and SOS button UHF receiver. Includes
LED indication of RC connection:
green: waiting for Bluetooth connection
orange: BT modem is restarting
blue: Bluetooth is connected
red: triggered by pressing the SOS button on the RC,
illuminated for 10 s
5
The perimeter of the top cover is equipped with an LED strip, which indi-
cates the status of the machine by the color.
At startup, the machine signals the following:
1. Test of the LED strip after the first 15 s after switching on the machine
— white turning into color waves. After a successful test, the machine can
be driven but cannot start the mowing deck. This condition can be used,
for example, to move the machine to the working area.
2. Waiting for other subsystems to start is indicated by a yellow "snake" on a
blue background, which normally lasts up to one minute after the machine
starts.
Other signals are related to the mode in which
the mowing is carried out.
Manual mode is always indicated by a green flashing light. The blinking
is long if the machine has an accurate position, i.e. it has a valid position
determined by GNSS and is receiving position correction data. Conversely,
the blinking is short if these conditions are not met. If the safety bumpers are
activated, the machine's LED strip will flash red with a yellow background.
SUMMARY:
Manual operation with RTK FIX:
— With mowing deck on:
Manual operation without RTK FIX:
— With mowing deck on:
green flashing long
running green
green flashing short
running green, flashing
The autonomous mode is terminated, among others, by pressing any safety
bumper, which is signaled by a red LED strip with a yellow background
(flashing) and the machine then switches to manual mode (green flashing).
If the machine is on a slope with an inclination greater than 60 degrees, the
motor will automatically shut down and the machine's LED strip will flash
rapidly in red. This is for the protection of persons in a situation where the
machine could tip over.
If the operator tilts the remote control more than 90 degrees, the machine
will automatically stop, stop mowing and the machine's LED strip will flash
rapidly in red.
The operator can stop the machine via the UHF emergency channel (SOS
button) using the remote control, where the machine automatically stops
and mowing deck stops. The machine indicates this condition by a rapid
red flashing of the LED strip.
In the first phase of Perimeter Mode (manual guidance of the machine
around the mowed area), the recording of this circuit is signaled:
FIRST PHASE:
Manual driving with RTK FIX:
— With mowing deck on:
Manual driving without RTK FIX:
— With mowing deck on:
PHASE TWO:
See the Autonomous Mode signaling below.
After successful entry into Autonomous Mode, the following states are
signalled:
Autonomous operation with RTK FIX:
— With mowing deck on:
Autonomous operation without RTK FIX:
— With mowing deck on:
If the conditions for entering Autonomous mode are not met (machine is
not calibrated, start of route is too far away, etc.) the LED strip lights up
orange with red edges.
The machine includes a siren that sounds:
Before starting the engine and serves as a warning to persons in the
vicinity of the machine.
Once the mower enters online mode in the user portal.
After successfully uploading the map from the server.
