  • It’s true, it can’t detect exactly where the largest object is in it’s field of view, but that’s a limitation of using ultrasonic sensors instead of others like IR/laser range finders with a much more limited detection zone. The workaround (and one of the best ways of taking advantage of the large cone) is to use two sensors instead of one, and use triangulation to determine where the largest object is in a plane. If you also need to, you could add a third in order to determine the exact position (+/- ~ 1cm) of the detected object in 3D.

No public wish lists :(
