No, is not. I am in "desperate mode", so, by now I am using only the NXT brick
and the US, and trying to figure out more information about this condition...

I realize now that the black grid in front of the right "eye" of the sensor is
turned about 30', since the other one is perfected aligned. I dont know if it is
decorative only, or may indicate that this sensor component is misplaced, or
something like this.

Any tips would be very appreciated.

(...) I don't think that's an issue. In the sensors I have the mesh is not straight. Steve (20 years ago, 15-Oct-06, to lugnet.robotics.nxt)

(...) Is this sensor mounted on a robot? Make sure you don't have anything anywhere in front of the robot. Steve (20 years ago, 15-Oct-06, to lugnet.robotics.nxt)
