 Game Summary


For a more detailed explanation, see the Wikipedia article and the game animation.

This year's field is open, with only a truss crossing over the middle, 10 point goals at each end of the field, 1 point goals in each corner, and 3 zones on the field. The game pieces are large 28 inch diameter inflated balls.

The match begins with a 10 second autonomous mode period, where the robots can shoot balls autonomously into goals. Each side of the goal is lit up as 'hot' for 5 of the 10 seconds, gaining extra points if a shot goes in while the goal is 'hot.'

During the 2 minute teleop period, each team must score any missed autonomous balls into either the 1 or 10 point goals before a 'cycle' can start. A 'cycle' begins when a robot in the first zone of the field takes the ball. An 'assist' is defined as one alliance member possessing the ball in one zone of the field. 10 points may be gained by launching the ball over the truss, and another 10 may be gained by having another team catch the ball, though the ball may also be passed to a human player or simply left to bounce around the field. 10 points are awarded if the ball is shot into the main goal, and 1 point is awarded if it is dropped into the 1 point goal. Upon score in either goal, assist points of 10 points each are awarded.

 Fun Facts/Stories


This is the first year we built a second robot, and also the first time we got our robot powder coated. Our second robot, named Larry, was never powder coated but was otherwise largely the same.
