Re: Common or uncommon sensors used in FRC

My former team always used the old rotary limit switches that were distributed in the KOP up until 2011. I think that they can be found at this link, but I'm not entirely sure it's the same model.

They are extremely helpful for implementing soft stops for arms, kickers, and dumpers. We simply plugged them into the input pins in the DSC, and programmed the robot such that the motors can not rotate in certain directions when the switch is activated. From what I heard, this can be accomplished easier by plugging the limit switch directly into a Jaguar, and using jumpers to determine which directions the motor can rotate when the switch is activated. You will have to consult the Jaguar information sheet for this, though, as I have never attempted this.
