Official FIRST Stronghold Teaser!

[Shifter]

From the field map:

Lanes up the left side of the field allow a human player to draw back the tent flaps at mid-field that otherwise prevent drivers from seeing the opposing end of the field. Withdrawing both red and blue curtains for the majority of the match raises the yellow flag and increases co-op points. As long as the flaps stay “closed”, the drivers must rely on hand signals from their human player or cameras mounted to their robot when trying to score in goals at the far end of the field.

Three moveable goals start on the driver’s right on the near side of the field. Lines on the field map show where two of the goals have been dragged to the left side of the field for protection. Note that the human player on right side wall loaded game pieces into one of the goals on it’s way by. North/south lines track game pieces being thrown by a human player toward the relocated goals.

From the flags:

Shapes on the red and blue flags represent round balls (or maybe hex balls) being scored in one of three, three-compartment hexagonal floor goals. Game pieces are red, blue and yellow. Most balls in a goal (somehow) raises a flag of that color – red flag counts red balls in the goal for the red alliance; blue flag counts blue balls in the goal for the blue alliance; yellow flag scores total of all balls in the goal (red, blue and yellow) for both alliances.
