Ultrasonic Sensor Issue
Hey all, our team uses the ultrasonic sensor that comes with the kit (LV-MaxSonar-EZ1 - Maxbotix) but recently we've been experiencing some issues with it. At the beginning of autonomous, our robot moves forward until a certain voltage is passed by the sensor to indicate its close enough to the rims; however, in some of our matches, the sensor gave us an incorrect reading, which made our robot shoot its balls prematurely (its a dumper robot). Would any loud noises such as loud bass music cause the sensor to pass an incorrect value and feed the robot a smaller value than it actually is? Is anyone else experiencing similar problems with this sensor? Thanks.
Also, would adding in a second at the beginning of autonomous for the robot to get the average values at 5 distinct times (say, 0.2 secs into auto, 0.4, 0.6, 0.8, and 1 second) work? In the code, as soon as a value lower than 0.55 is received our sequence structure moves onto the second frame; would taking an average value ensure that one faulty reading wouldn't mess up autonomous? Much appreciated.
