Proximity Sensors


Proximity Sensors

Proximity sensors measure the relative distance (range) between the sensor
and objects in the environment. Since the sensor is mounted on the robot, it is
a straightforward computation to translate a range relative to the sensor to a
range relative to the robot at large. Most proximity sensors are active. Sonar,
also called ultrasonics, is the most popular proximity sensor, with infrared,
bump, and feeler sensors not far behind.
