Stationary beacon
-
Usually, mounted on the walls or ceilings above the robot with
ultrasonic sensors facing down
—to provide the most robust
unobstructed ultrasonic signal coverage to the robot.
However, for automatic landing and indoor navigation of
copters, for example, it is recommended to install mobile
beacon horizontally on the belly of the copter so that the
beacon would be looking downwards
-
The position and orientation of the beacons should be chosen
in a way that provides maximum ultrasonic signal coverage.
System efficacy strongly depends on the quality of ultrasonic
signal received by stationary beacons
-
Stationary beacons emit and receive ultrasound
during the map configuration period. Once the map is formed and frozen, they only work as
the receivers
-
Stationary beacons have no exterior differences with regard to mobile beacons
-
Inertial measurement unit (IMU) is not installed on the stationary beacons
-
The mobile and stationary beacons can be easily interchanged during configuration in the
Dashboard
-
There are 433MHz and 868/915MHz versions available. A proprietary radio protocol is used
for communication and synchronization. Other ISM bands are available upon request as
well
-
Stationary beacon can be equipped with full-size 165mm antenna (for 433 MHz), which
provides more robust radio connection between modem and beacons (for HW v4.9)
