Stack Attack was the game for the 2003 FIRST Robotics Competition. Two teams of two robots compete by moving large Sterilite bins into their zones and arranging them into stacks. At the beginning of the match, each team is given 4 bins, which they may arrange as they see fit. Each of these bins are marked with a retroreflective tape that is highly visible to the infrared sensors included in the kit of parts. In the center of the field on top of the ramp is a large stack of 29 bins.
The object of this game is for each two player alliance to rack up more points than the other team. Scoring is one point for every bin in an alliance’s scoring zone, multiplied by the height of their highest stack. Each robot on the top of the ramp at the end of the match adds 25 points to an alliance’s score. Bins that are supported by a robot do not count towards the final score.
