Go to Post I find this ironic. In English class our teacher's tell us how there is symbolism and such, and we don't understand it or think its there. Then FIRSTer's get a Game Hit, and we think EVERYTHING is a symbol and has some significance. - akoscielski3 [more]

Using Ultrasonic Sensor

We are interested in any information about how a team may have used the MaxSonar on your 2012 robot?
We are working with sensors over the summer and program in LabVIEW, but can understand some equivalent C code.
We were hoping to use the sonar to backup to a fixed object about 5" away, but the sonar does not seem to update in real time for us and when testing the sensor on the bot, it varies wildly in accuracy.
Off the bot outside of 6" we seem to have repeatability within an inch. Actually the farther away we get, the more accurate it seems to be. We would appreciate any feedback. Thanks.
Addition, okay, I read the spec sheet and it's not supposed to work closer than 6". So that's working the way it is supposed to. Would still appreciate any info about how the sensor was used by other teams.
