A Radio is any object that uses radio waves to send signals. An OM5P-AN Radio was included in the 2016 control system. Before that, a DAP-1522 Rev. B Radio was used, from 2013-2015. The radio that will be included in the 2017 control system is the OM5P-AC, though the OM5P-AN can still be used at competitions.
