9.14. Proper ultrasonic coverage
The single most important requirement for the system to work well is to have proper
ultrasonic coverage
Each sensor has an ultrasonic beam of ~90 degrees. Outside of that range, the emitting
power and sensitivity drops quite rapidly. From the left, right, or back of the ultrasonic
sensor, the signal is highly attenuated. Thus, it is crucial to provide proper ultrasonic
coverage for the area where the robot will be moving.
-
It is also very important to provide proper ultrasonic coverage to the stationary beacons when the
map is being formed
-
Mobile beacon (
“hedgehog” or “hedge”) is designed to be placed horizontally
-
The mobile beacon has four horizontal and one vertical sensor, each covering its own sector.
Together, they cover 360 degrees horizontally and 180 degrees in the upper hemisphere. The lower
hemis
phere is highly attenuated, so don’t expect ultrasonic coverage in that area
-
It is advised that the mobile beacon be placed as high as possible on the robot if the stationary
beacons are above the mobile beacon. This minimizes shadows from other objects, people, etc.
