Scoring Ideas

I. Why do we need complicated tie breakers (in Qualifying matches) to insure a win/loss? I recommend that ties be allowed, where in the event of a tie, both teams score QPs according to either:
1. 1.0*score (same as a loss for both teams)
2. 2.0*score (compromise)
3. 3.0*score (same as win for both teams)

In determining record you would have W-L-T.

You would need tie-breakers for elimination rounds.

II. Idea for autonomy...If different colored "balls" are going to count for different points, and some "balls" may deduct score, then, if we had a sensor which could give a signal when presented with this "negative color" we could have our robot make decisions and select which balls it chooses to pick up (for instance, a sensor which "sees red").

Another idea for autonomy is to put the "balls" in a box or bag that the robot would have to reach into (the driver couldn't see what he was getting). An autonomous gripper, with appropriate sensors, would only require the driver to get the appendage into the box. The gripper would sort through the balls.

Or, an enclosure with a 1'-2' high vision-blocking wall. You could still see enough to drive the robot in and out of the enclosure, but you could not clearly see balls on the playing field with enough certainty to reliably distinguish between red and blue balls.

If the game requires red alliance scores red balls and blue alliance scores blue balls, then interleaving balls on the playing field would encourage a device which can "sort by color." In other words, you would not need "deductive balls." If you just picked up a bunch of balls and scored them, you would score an equal number for both you and your opponent.

III. On using footballs with a human player. It is much easier to throw a football 40' and hit a small target than a soccer ball, beach ball, or basketball. If the game involves putting balls in goals and the balls are footballs, the human player would become too important.

IV. In defence of soccer balls, now that teams can reliably manipulate them with robots, you can have some pretty cool things going on in the game. If the game were to involve new, non-round "balls," you will probably only have a few teams effectively manipulate them.

Although the temptation to design a fribee hurler or a football place-kicker is nearly over-powering, I would rather design "Ball shooter, mark II" and get it tweaked out this time.
