At each event, the ARENA will be open for at least 30
minutes prior to the start of Qualification MATCHES, during which time teams
may survey and/or measure the ARENA and bring ROBOTS on the FIELD to perform
sensor calibration. Events may schedule additional measurement and calibration
times. The specific time(s) that the FIELD is open will be communicated to
teams at the event. Teams may bring specific questions or comments to the FTA.
