Quanser Qbot: User Manual
4.2.6. Sonar Sensors
The MaxSonar-EZ0 [6] is a very short to long-range detection and ranging sonar sensor
(Figure 10). The MaxSonar-EZ0 detects objects from 0-inches to 254-inches (6.45-meters)
and provides sonar range information from 6-inches out to 254-inches with 1-inch resolu-
tion. Objects between 0-inches and 6-inches range as 6-inches. There are three of these
sensors included with the Qbot. The sensors are connected to the other input channels of the
Qbot DAC, which can then be read using the HIL Read Write block (Section 5.3).
