Re: New VEX Game Announced!

Disclaimer: I am not a VRC member, and it's doubtful that I will be. (Sadly ).

Okay so my perspective on this games winning strategy is that whatever team can get the most balls onto his own side in autonomous will win. Lets say that the winning alliance has 2 robots that can succesfully pull the small balls out from under the wall while taking the footballs from the posts and the one in between the posts. I predict that the finals will have no autonomous scoring (except on ones self), because the 5 points will be irrelevant if you can get 6 footballs (3 per robot) and 8(each robot takes 4) small balls onto your side. This gives 17 small balls on your feild, 4 available due to preload, and 8 sucked from under the wall. That is 29 points from small balls, while the opposing alliance has 21 points (17 + 4). Now as for medium balls, 5 on your side, 1 from preload, and 6 knocked from wall. That is 60 points. Assuming that the opposing alliance would take the other 3 medium balls (sitting in the center), they have 11 balls (6+1+3). So far the score is 89 - 71(5 extra for autonmous bonus), of course the dumps would not occur until the end. Now that the balls are on your side one robot would collect the balls while the other would bring the other blocks the goals to ensure that the other alliance could not pull ahead. Now because the large balls are worth 10 points the other alliance could score and the points would weigh out 81-89. This does seems close however, if the robots are designed to function perfectly in autonomous, I feel that this could be a winning strategy.

A robot that can succesfully take at least 5 footballs (from the wall) in autonmous would work just as well, but is probably harder to do that fast enough.

Keep in mind that the score is assuming that the other alliance is able to both take the 3 medium balls from the middle wall before you do and score their large ball. So this is worst case senario as long as you perform your tasks correctly.

The primary scoring robot (the one that collects for the 2 minutes), would need to be able to score over any form of defence, so that eliminates scoring through the base, although it would probably be able to reverse the mechanism that sucked up the small balls. The "shooting" mechanism would probably need to be similar to 67's (FRC) robot except aim higher.

The second robot, known as the defensive robot, would be slightly trickier to design (maybe). It would have to get a cover for the goals and a mechanism that knocks medium balls of different heights and can suck the 4 small balls from under the wall. It wouldn't have to nessicarily be able to score these balls just get them onto it's own side so the "primary scorer could pick them up. This also mean that the preloaded balls would have to leave the robot for the primary scorer to use.

Some harder problems to over come is getting a hopper space to accomodate 29 small balls and 12 footballs. Unless the defesive bot scores, this would have to fit in one bot, and be expelled within aproximately 5 secs. I think a hopper that expands, similar to FRC 45 (i think) in 2004. However, this stress would be alleviated if the defensive bot scored.

The question I would ask is, what should I depend another team to innovate and what should I innovate?

My $0.02

There are proably other strategies which involve scoring the large ball and/or scoring in the goals and/or scoring in autonomous (on the other team), however, I feel this one covers most basis, the tricky part is getting two robots together that can do these tasks and do them well. And I could be 100% wrong and off-base, just giving my opinions.
