| | | (...) At a glancing angle (not approaching the wall "head on" at 90°, but at an angle) very little sound energy will be reflected back towards the sensor. If there isn't enough energy reflected back for the sensor to "hear" the echo, it won't detect (...) (17 years ago, 22-Dec-07, to lugnet.robotics)

| | | | Strangely, it slows down, i.e. it detects the further distance (less reflection?) in the same angle. I tried to put the US-sensor vertically. It still shows the same effect. I also notice the closer it comes the larger angle it needs to get a (...) (17 years ago, 23-Dec-07, to lugnet.robotics)

| | | | | (...) That is a very interesting site, with some interesting information... but you might like to do those experiments yourself. For instance, the odd "ledge" in their data at 48 cm is not a feature with my US sensors - they may have been working (...) (17 years ago, 25-Dec-07, to lugnet.robotics)

| | | | I tried to use a program to log the distance while the US-sensor is moving forward. Unfortunately, it doesn't go straight all the time. So, I simply display the US value and put the vehicle in different position manually. Here are my test values for (...) (17 years ago, 27-Dec-07, to lugnet.robotics)
