Clearly this applies to rollers, belts, etc used to pick up the balls that could be reversed to release the balls - they impart a dynamic impulse to the ball, so they are a shooter.
However, this would not apply to a trap door MECHANISM. That does not impart any force to the ball - gravity does that. Gravity doesn't qualify as a MECHANISM under Section 5 because it is not a COTS or assembly of COMPONENTS. So any aiming extension (fold down door, etc) that directs the balls toward the corner goal should be allowed, provided that the balls are only rolling downward.
This is supported in Q&A http://forums.usfirst.org/showthread.php?t=429 (previously quoted in this thread) because of the warning about becoming a wedge. In answering this question, the GDC implied that the ramp might be outside the original footprint, thus the warning about <R04>. If the ramp MECHANISM had to stay entirely within the original footprint, there would be no wedging possible, unless the ramp was designed as a leading edge with no bumper.
Even a dumper hopper, as shown at kickoff, does not fall into this category. While the MECHANISM moves, it is gravity that imparts the final impulse, not the hopper. The raising of the hopper is no different than any other MECHANISM that lifts balls from the floor - it imparts potential energy to the balls in raising them, but does not deliver a final dynamic impulse.
Just my opinion, I could be wrong. |
Let me counter your nitpicking with more nitpicking
(I mean no offense by saying your “nitpicking”, but that’s what we are all doing here)
Here is my take on the whole hopper with door thing:
Ok, so let’s say the door is within the bounding box, but your hopper is a big V that at its top is much wider than the bounding box. Without that hopper, the ball would not be funneled down towards the door, and the balls would be on the floor, and the point becomes moot.
Remember the shooter mechanism is 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.
So, since gravity may be the final impulse that drops the ball out of the hopper, the hopper is still imparting a force and touches the ball while that force is being applied.
So in my eyes, a hopper with a door would be a shooter mechanism and must stay in the bounding box.
This should be the first YMTC of the season! XD

This is exactly like 2005 games and the robot touching the triangle before using a human or auto loading station. Throughout the season, it was never changed, everyone assumed breaking the plane would count, but that’s not what the rule said, it never changed from day one. FIRST simply reiterated what they meant in the QA
