Ultrasonic Range Sensor
Brief Description
A range sensor measures the distance
from a reference point (usually on the sensor itself) to objects
in the field of view of the sensor. Range sensors are used
for robot guidance and obstacle avoidance someplace estimating
the distance to the closest object is of interest, general
shape characteristics of object in robot workspace are also
estimated. CSIO has developed one such system, which has been
successfully tested and used for imaging applications It uses
a pair of low cost.40 KHz piezoelectric crystals. One crystal
acts as transmitter of ultrasound which after reflection from
the object is received by the other crystal. A microcomputer
finds the time-of-flight of ultrasound which is linearly related
to the range.
