The 469 auto

[JABot67]

I'd like to understand your auton strategy, but it looks like your post got all messed up. Perhaps CD does not like too many spaces in a row. Try using the code tags, like this:

----------------------------------
Insert         Field          Here
----------------------------------

Aaaaaaaw it did...


that stinks ill redraw it in paint...

Ok I fixed ithttp://question

I hope this works

469's strategy is brilliant, because in order to stop them you have to not only prevent them from getting to the tower first, but you also have to camp there the whole match so they never can get there, since once they're in position you really can't get them out. So while you're keeping them from getting to the tower they're free to do whatever they want. And you have to move out of the way in the last 20 second, or you'll get a penalty for contacting the opponent's tower...pretty beastly strategy, I can't wait to see video of them.

ya I realize that but lets say for instance 33, 910 and some other team was on an alliance against 469, 217 and some other team.

Senerio one: A effectivly a 3 on 1 with the third team to block/pin well 469 recycles balls and 217 puts in the misses. The other two teams try to keep up with them on the other side of the field but undoubtly fail, they can't keep up with a ball every 4 to 5 seconds.

Senerio two: In the beggining of the match our third team wedges themselves under the tower. Then team 33 now has a fighting chance for the balls in the middle. 469 has dificulty turning. However 217 is still a huge threat. 33 is now playing a 1 on 2 tring to shoot balls down to 910 to to score. We have to count on 910 ten being able to beat the defense and 33 quickly passing balls down. Overall, its not looking good.

ps. The reason I use these teams is because this is a realistic possibility at Troy in week 4.

Did anyone have a bot at Cass that could redirect the balls back into middle after the balls rolled off 469? Was this even tried or is the ball to low coming off 469 to send it back over bump?

[JGurnow]

The balls are below the bump when the balls leave contact with their robot. You need to intercept the ball and kick it away to stop the strategy. Another team tried hitting the tower as the balls were coming down and that doesn't stop balls from being scoring.

Its a very good strategy, stop 469 and the match is 3v2, don't stop them and you can't outscore them.

469 has no problems pushing robots out of the way. It has obscene grip and is geared low to push anything out of the way. They can push and turn opposing robots with the bests of them.

Notes on 469's drivetrain:
8wd with pneumatic tires, 4 CIM through DW trans, I don't know the exact gearing.
Pneumatic articulated Front and Rear wheels (I don't think separately)
Pneumatic articulated ball casters in rear.
No ability to change zones (I guess they could go over the bump, but that probably wouldn't end well with that tower on top)
Pneumatic lock to tower - It locks to the bottom of the tower. They aren't just shoved in the tunnel, they are locked there. They aren't coming out once they get in, at all.
*should* turn well with outer wheels up

Autonomous start positions:

---------------------[OUR TOWER]----------------------
                                   [their robot]   
   







                [Our robot]
--------------------[THEIR TOWER]----------------------

We can get to their tower before they can, if we can do it in Autonomous. Then they would be stuck playing a regular game, without recycling balls. I didn't get a good look at their ball-o-fier or kicker, but both exist and are capable of acquiring and kicking a ball.

If the balls are below the bump, then they're coming out under the Bumper Perimeter...

I think he meant to say that the balls are below the bump when they leave the tower/bump area. Looks like they guide them down onto the back side of the bump to deflect them horizontally and eliminate bouncing.

In which case, you could have one defender in the zone and a second resting on the bump to stop transfers on one side.

Another robot can't physically get in the way on the bump. Their mechanism has maybe 3-4 inches of space below it and the top of the bump. You can't get into that position without causing physical damage to 469 which is against the spirit of FIRST.

I don't think you quite get that when 469 is in position the rest of the alliance is in the homezone. Only one needs to defend a robot. The other robot is there for clean up.

469 could traverse the bump without the tower on it. I am unsure, as are they, about whether they could go over without flipping now.

[BJC]

On the contrary I am very aware of this.

The only way to prevent a blowout is to lodge yourself at a 45 degree angle in the tunnel in auto.
Then even with crazy traction 469 will have a hard time pushing someone out of that position who also has traction because their isn't a good way to push them from.

That being said it doesn't really matter anyway because for the next two regionals their in their pretty much going to be with you (217) so Troy and the Michigan Champs are going to see the exact same thing Cass tech did.

You can call me a pessimist but I call them as I see them.

Ok, some team in their six hour window just needs to build a robot that is strong, fast and agile. Now all you have to do is stop their first attempt and play heads up defence, pestering them but keeping yourself b/t them and the tower.
