Odd NXT Ultrasonic Sensor

/ 13 September 2006

A few days after I got my NXT it’s Ultrasonic sensor started to lose it’s ability to sense far away objects. But in the past few days (that I’ve had the rechargeable battery) it’s grown super-sensitive, seemingly sensing a piece of dust, as the program I’ve been running day and night keeps making it move it’s motor (the action that an object 9 inches away makes it do) when I’m sure nothing is within 50 inches of the sensor. Has anyone else had this issue? Because it actually creeps me out sometimes, since it runs it’s motor when I don’t expect it too.
