Thanks Jon for the quick reply
I was hoping this sensor would measure the distance of a laser point (like a laser pointer) reflected on a target surface. That would be ideal for me. Nevertheless, the 25° FOV is approximately half that of the Maxbotix XL-MaxSonar-EZ4 Sonar Range Finder I am currently using (the narrowest beam in the series).
I noticed that when perfectly aligned with a narrow passages between objects (say less than 24" wide but over 6 ft long), the sonar returns objects at close distance. The robot then "believes" there is no passage in that direction while there is.The 25° FOV should perform better in this kind of situation.
Also, by combining multiple readings at angles smaller than the FOV (e.g. 5° apart) I can estimate the probability of having an obstacle at a certain distance within each angular sector which can increase the reliability of the mapping.
I'll give it a try and see how it performs!
