Definition of Dynamic Impulse

[FRC195]

The intent of rule <S03> has been made quite clear in the recent Q&A posts, and its redefinition in Team Update 6.

SHOOTING MECHANISM: the mechanism that delivers the final dynamic impulse that ejects the ball from the robot, and any parts of the robot that contact the ball while and/or after this impulse is delivered.

It has been made clear the term 'Shooting' is not limited to the upper goal, but can also be applied to rolling balls into the lower one point goals. It has also been made clear a 'Shooting Mechanism' is anything that expels balls from the robot.

By the current definition, balls pushed into the corner goals by any part of the robot outside of the starting envelope would be illegal, based on the reasoning that the moving robot is giving a dynamic impulse. Is this true? Can balls be rolled into the goals by moving parts (such as the robot chassis or extending plate) if they are initially on the ground?

A shooter is any system that can eject a ball from the robot (see this question/answer). Plows on the exterior of the robot would not be considered "shooters" because the ball was never contained in the robot and therefore cannot be "ejected." Plows that roll balls into the corner goals are legal, and are not limited to the 28" x 38" starting footprint specified in Rule <S03>.
