Stack Attack required a robot to collect and stack plastic storage containers on their side of the playing field. The precise location of the robot, containers, and height of the stacks determined the score for each alliance.

The Field

The field measured 24 feet wide by 54 feet long. A ramp was located in the center of the field with 29 containers located across the top of the center platform in the shape of a pyramid. On the outside of the perimeter were four containers for each human player. Robot starting locations were to the sides of the ramp and alliance stations were on the opposite sides of the field.

Game Pieces

The containers located at the center of the field resembled those of a normal large container found in everyday households.

Autonomous Period

At the beginning of each match, the human players had ten seconds to stack the containers in any configuration in their scoring zone. After this period, human players rushed off the field and the 15 second autonomous period began. Teams were able to pre-program their robot to perform certain functions and maneuvers without the control of the drivers. During this period, robots could use their sensors to track the tape located on the field or use dead reckoning to navigate to the center stacks.

Teleoperated Period

After the autonomous period was the teleoperated period. Alliances attempted to gather as many containers as possible and stack them on their side of the field. Not only did the robot have an opportunity to stack, but it also had a chance to knock over the opponent’s stacks and to protect its own stacks as well. Before the match ended, alliances had a chance to drive their robot to the top center of the field to earn bonus points.

Scoring

The final score was obtained from multiplying the number of containers in the highest stack in the alliance’s scoring zone by the number of containers in the scoring zone, exclusive of the containers in the highest stack. Any robot positioned at the top center of the ramp was worth 25 points.
