Re: Is your robot defense ready?

If the red ball (or 2 or 3) is on the floor, and two blue bots can take turns hitting it (or hitting red bots trying to pick it up) to keep it on the floor and out of possession by red bots-- and one blue bot can make cycles without ever putting the blue ball on the floor (or holding it precariously in front of itself) then blue can win (albeit with less assists than they might like.)

I think a very competitive bot design is one that can get loaded in a secure hopper above the frame by a human (bot preferably not needing to be stationed at the field wall to still reliably receive), then truss toss and catch in its own hopper reliably (I know, no catch points for that) and then score, preferably 10 pts.

This bot can score 20 pts (and one assist -- since a solo run is one assist) on very fast cycles with low risk of loss of ball control, with the only effective defense being bots getting in the way and/or playing goalie. The bot's two partners can play full on defense- taking turns bumping the ball in the wrong direction and significantly slow down any cycle strategy that puts the ball on the floor to pass or where its easy to have a bot lose the ball via a strong hit due to insecure possession.

All three human players in alliance station can speed up cycles -- one at pedestal, one at corner and one at inbounding location -- ball is tossed from player to player to inbound as quickly as possible.

As long as the team is not too far behind after auto, it should be able to get/keep ahead with a robust, fast, low scoring cycle against a largely disruptable strategy that puts the ball at high risk of possession loss.

The top teams/alliances will have full control/carry-possession of their own ball and will control (but not possess) their opponents ball as much as possible. If you can't guarantee a reliable CATCH or a reliable self or human catch or human catch after a TRUSS, its probably not going to be worth doing the TRUSS, if your opponents are playing smart.
