Proximity Sensors for FRC?

[cyberius]

Hi guys, I would really appreciate your help with finding the right proximity sensors to buy for the 2017 FRC competition. This is just my team's second year participating in FRC, and we really don't have much experience on the subject. We were thinking of using the sensors for guiding our robot during the autonomous period, and need them to be able to detect surfaces at approximately 3/4 meters away. What type/brand of sensor do you recommend that we buy? Which are compatible with the NI roboRio? Any help is appreciated, and thanks in advance!
