Is there any further information about the built in ultrasonic sensors?
I would like to use the provided ranges in RViz, which uses the
These fields are unknown to me:
float32 field_of_view # the size of the arc that the distance reading is # valid for [rad] # the object causing the range reading may have # been anywhere within -field_of_view/2 and # field_of_view/2 at the measured range. # 0 angle corresponds to the x-axis of the sensor. float32 min_range # minimum range value [m] float32 max_range # maximum range value [m]
It would be great to know these three parameters!
Thanks in advance
