FIRST Overdrive was the 2008 game for the FIRST Robotics Competition, announced on January 5, 2008. In it, teams competed to complete counterclockwise laps around a central barrier while manipulating large 40 in diameter “Trackballs” over and under overpasses to score additional points.
FIRST Overdrive is played on a 54 ft by 27 ft carpeted field, divided lengthwise by a fence median to create a track, and separate the field into Red and Blue zones. The fence is crossed by an overpass marking the red and blue finish lines, and hold the game pieces: 40 in diameter inflated balls called “Trackballs”. Two three-team alliances race around the track in a counter clockwise direction while manipulating the trackballs to score points.
The game is made up of two scoring periods. The first 15 seconds of play is the Hybrid period in which robots are autonomous, and may also respond to certain digital signals sent by team members designated as “Robocoaches”, who are stationed at the corners of the track.
The next two minutes of play is the Teleoperated period. At this time, robots are fully radio controlled by the team operators standing at either end of the field.
