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 (1 m) diameter "Trackballs" over and under overpasses to score additional points.

Game Overview

FIRST Overdrive is played on a 54 ft (16 m) by 27 ft (8 m) 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 (1,016 mm) 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.[4]

Scoring

During the Hybrid period, robots traveling in a counter clockwise direction score:

During the Teleoperated period, robots traveling in a counter clockwise direction score:

Alliances score an additional 12 points for each of their Trackballs that are positioned anywhere on the overpass at the end of the match.[4]

Hybrid period

Hybrid period is a new addition to an FRC game. Rather than the pre-game autonomous modes of previous years where robots were prohibited from receiving input from humans, robots may receive signals via an infrared (IR) remote control or visible light from a designated Robocoach during the Hybrid period. The number of different IR signals the IR board included in the kit of parts is physically able to receive is 4. The number of distinct commands that are allowed to be sent is also 4, thus ruling out multi-signal combinations.
