So an all shooting alliance would have to score 90 points and hold the other alliance scoreless.

Please explain the logic behind 120 points in just climbing. The Max is 30 for each team, and an alliance has 3 teams.:confused: 90 points....?

Perhaps assuming that 6 colored disks are scored by the climbing alliance?

Assuming the quote I am going %100 climbing only.

You also can't preload colored discs, so on those grounds the dedicated climber bots would probably need a solid drive system to load those discs, and capable storage for getting the 5 pointers. You might as well just have a dump robot then that doesnt need to shoot, but just dumps 1 pointers, and then climbs. That way it can be a climbing robot, but can gain easy dumping points

This would be some of the most epic Einstein matches ever if we saw scores like this. I can only hope it happens.

I think that the ability of teams to build successful 30 point climbers is being a bit overestimated. Given how some previous end games have gone (and I think most previous end games are easier than this one) there will be Regional events where maybe one team at the entire competition can successfully climb for 30, and it may not be consistent. I could see it at IRI but I think it will take the stars aligning for a triple 30 point climb alliance to form even at the World Championships. I just don't see a good 30 point climber being left for a 2nd pick anywhere.

I still really like the climbing and dumping bot idea, and could see a robot like that seeding #1 at a regional if it is built to execute consistently. 30 climb points, 20 dump points, 6 autonomous points, and 12-20 low goal points a match depending on how it loads would give it close to 70 points a match. That's pretty much unbeatable in most qualifications barring an unlucky pairing against 1114 and 67 at once. An 18 point autonomous shooter with a 10 point hang still needs to hit 4 volleys of 4 disks with near 100% accuracy to stay even with super dump bot.

So far 1757 is going with a shooter as well as a grappling hook gun and a winch to hoist the robot to the second tier, thoughts?

12-20 low points is really pushing it...that's three to FIVE trips, not including your color run, across the field, not including ample time to climb up the pyramid and defense

Remember that you need to contact the first tier and get completely off the ground before going to the second rung.

Also, it's important to remember your teams ability, resources, past successes ETC before deciding on a strategy. A robot that can consistently climb to the 2nd level to will be successful at most regionals. Focus on doing one thing really well as opposed to multiple things at a lower ability.

Expect to have to demonstrate a ROBOT’S ability to constrain itself per B above during
Inspection. PLAYING CONFIGURATION constraints may be implemented with either
hardware or software.

I'm not sure the gun would be able to meet that requirement. Also, I'm pretty sure the gun is illegal under FRC rules. Maybe R08, R09.

I was hedging more towards 3, which would give a total score of 68. If you figure a climb takes 30-45 seconds then you have 1:15-1:30 for scoring those 3 batches of disks. The advantage super dump bot has is that scoring in the low goal should be 95%+ accurate and wouldn't take much time to line up for.

If a team could somehow fit a floor pickup mechanism in there to avoid runs to the feeding station then I think the design could push 80 points.

All of this is assuming pretty low defense. Defense will definitely bring the number of scoring runs down significantly (maybe 4-8 points), but defense will bring down high goal shooters' scores as well. It may even be disproportionate; if you can't keep super dump bot essentially pinned the entire match then it has 56 points that are not defend-able (6 points autonomous, 30 point climb, 20 point dump on top of pyramid), while the accurate high shooter has only 28 points that are not defend-able (18 points autonomous, 10 point climb).

However, you don't take into account the points they score DURING the teleop. Not to mention, I can garuntee there will be teams who figure out how to shoot accuratly AND get the 30pts for climbing. One of those bots could easily trump a dumb bot.

The dumb bot may be easier to build, but the work for an all-around is worth it.

The last part of that post is comparing points that can be scored while defense is illegal, e.g. autonomous and when in contact with the pyramid. Overall point potential I think is very similar between a 30 point climb dump bot and a 10 point climb shooter.

You made me realize an important effect of the rules I might have missed though, and maybe other teams did too. Is it illegal to defend against a shooter (make contact) while it is in contact with the pyramid but is clearly not attempting to climb? I will have to check the manual more closely to see. If so shooting bots could use the pyramid like the key was used last year.

I definitely agree that a do it all bot would trump either design I am comparing. But I think a do it all bot that works well is outside the capability of 95% or more of FRC teams, mine included.

G30
Regardless of who initiates the contact, a ROBOT may not contact an opponent ROBOT

contacting its PYRAMID or
touching the carpet in its LOADING ZONE.


Violation: FOUL. If purposeful or consequential, TECHNICAL FOUL. If an opponent's CLIMB is affected, each affected opponent ROBOT will be awarded points for a successful Level 3 CLIMB.

It seems that everyone believes the max you can score from the tower is 50. But I think if you make a robot that sort of has a glove for a feeder could possibly score some more 5 point frisbee's. If I am not mistaken you can throw the frisbee's at the end of the match. So, why couldn't the human player (with much practice) toss the frisbee at the glove and let the robot dump the frisbee in the tower goal. <- This being already suspended.
(I am not sure if this is legal as I haven't throughly looked at the rules.)

So basically use the "glove" as a backboard? This would be perfectly legal and would be a good strategy to try for 10 more points if no partner robots could score in the pyramid goal. Every match the human players might as well chuck their 6 colored frisbees at the pyramid goal to try to swing the match if they can, a robot backboard would increase the likelihood of making one of these shots. If we can get a climber working and go this route we might try that strategy...

Thanks for finding G30 Gregor. That definitely changes the game dynamic for shooter bots.
