(...) I think I understand. In this case, the limiting factor is the US sensor itself, how fast it can ing and interprete a return. Or from my standpoint (a physicist), it's a fundemental limitation of the physics of sound, not a limitation that has (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)

(...) The errors that occur are that the sensor does not properly report variable distances as it is positioned at varying distances from an obstacle. If you slow down the read rate then it works correctly (i.e., with a wait of ~15 ms between read (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)

Each test run used a different sensor. The delay (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)
