Team Image Description
Game
SUMMARY:
In the 2008 game, “FIRST Overdrive,” students’ robots are designed to race around a track knocking down 40″ inflated Trackballs and moving them around the track, passing them either over or under a 6’6″ overpass. Extra points are scored by robots positioning the Trackballs back on the overpass before the end of the 2 minute and 15 second match.
FIELD:
The field was split in half by a clear plastic barrier making an oval track. Each alliance’s finish line was in the middle of the field, one on each side of the barrier. The finish line has a 6 foot tall arch over it where the balls start the match at.
PRIMARY SCORING:
A salute to NASCAR, each alliance gets 2 points for every lap they make. If a robot pushes one of their alliance 36 inch diameter balls through the finish line first, it receives 2 points as well. If a robot puts the ball over their finish line arch, it receives 8 points.
BONUS ENDGAME:
Placing a ball back on its arch will receive 12 points.
AUTONOMOUS SCORING:
Autonomous crossing of each track line (4 total) receives 4 points. Autonomous removal of the ball from the arch receives 8 points.
PENALTIES:
(10 pts each) Moving clockwise around the track (each instance of breaking the plane of a trackline in the wrong direction). Posession of more than 1 trackball or posessing an opponents trackball. Pinning or refusal to allow a robot to pass for more than 6 seconds. Interfering with a robot putting a ball over the arch.
