System elements
3.4.1
Stationary beacons
-
Shall be mounted on walls and ceilings – usually, above the robot and ultrasonic sensors facing
down – to provide the most robust unobstructed coverage of ultrasonic signal to robot. However,
for automatic landing and indoor navigation of copters, for example, it is recommended to place
beacons on the floor/ground and install the mobile beacon horizontally downwards looking on
the belly of the copter
-
Position for the beacons and angles of
positioning shall be chosen in such a way that
maximum coverage in ultrasonic is provided for
the maximum territory. Proper ultrasonic
coverage is the utmost important element for the
system to function effectively
-
Stationary beacons emit and receive ultrasound,
when the map is being formed. And they only
receive the ultrasound, when the map is formed
and frozen
-
Stationary beacons have no exterior difference
with mobile beacons
-
Inertial measurement unit aka IMU is not
installed on the stationary beacons
-
The mobile and stationary beacons can be easily
interchanged by selecting the
option
(Except
IMU) in the Dashboard
-
There is 915MHz version available. Proprietary radio protocol is used for communication and
synchronization. Other ISM bands are available upon request too
