Any Wicked Awesome Goalies out there ?
We were just wondering it seems everyone is building ball shooters are there any wicked awesome goalies out there ? Are any teams building high goal or low goal blockers ?
It seem a blocking bot would be rather a sought after commodity ? |

It seems like you could block the low goal by just sitting in front of it.

There are 3 entrances into each low goal. A good low goal defender will need to do far more than "sit in front of it"

Re: Any Wicked Awesome Goalies out there ?
Our team has noted that most catapult and puncher shooting bots seem to only be able to hit the high goals and the top entry of the low goal . So we have concentrated on a blocker for these two areas . Has anyone else noticed this phenomenon also ?

Re: Any Wicked Awesome Goalies out there ?
During brainstorming someone suggested a goalie bot four feet long (possibly with a 20" extension that pops out at each end) by eight inches wide, 60" tall, and a drive system allowing it to speedily move sideways. Along the top would be a line of pneumatic pop-up blockers, which the operator controls with something like a piano keyboard.
Of course, this would completely block one driver's view if it wasn't made see-through. This led to speculation about an anti-goalie bot whose main strategy would be to block the opponents view, and whether such a monstrosity would violate gracious professionalism. ![]() |

I think most people are over 5' unless the extensions somehow build a wall

Re: Any Wicked Awesome Goalies out there ?
Due to the rule about the 6 inch cylinder going above 5 feet i can't imagine how hard it is to be a good goalie.
Though if simbotics, robonauts or one of those other fantastic teams build a goalie that doesn't allow the opposing alliance to score they will obviously win. Only time will tell though. ![]() |

If a ROBOT is in contact with carpet in its GOALIE ZONE, and for only one ROBOT per ALLIANCE at a time, there is no height restriction; however, any extension or combination of extensions above 5 ft. may not extend beyond a vertical cylinder with a 6 in. diameter. Our high goal blocker can zip up to 112 inches and can withstand the blunt force of the direct hit of the ball with out toppling over the robot. We are new to this being a rookie team . The team just wanted to be good at one thing blocking shots. In the hope that we were a valuable asset . |

Defense is unappreciated because it's value is not directly apparent in the score. Preventing or delaying a cycle is the same as scoring. |

So moral of the story? Defense really does help. All 2386 was able to do was defense and score in autonomous. By us not being able to compete match two and losing by over 50 points (we were usually 50 ahead), showed just how valuable our defense was. We were quite pleased with how us not being able to play in match two, showed that we hadn't just won a lottery, but we actually greatly helped our alliance in getting to where it did. Defense is totally underrated. |

Defense is totally underrated. I can see that defense will be a major part of the game after the ball is passed to your alliance member. You will have nothing else to do while you wait for the robots on your alliance to score for the next ball to be put into play. So I can see defense becoming a big part of the game after these week 1 competitions coming up. ![]() |

Re: Any Wicked Awesome Goalies out there ?
Okay, this is something that we came up with at the beginning of build season but never used it (blocking is not in our strategy). The perfect blocker would be a large pole mounted on the edge of a lazy-susan turn table. When you wanted to block you have a motor turning the table and the previously small rod now takes up close to three ball widths (or more) Couple this with rapid robot movement and it could become a very effective blocker.
https://encrypted-tbn0.gstatic.com/i...IXJv_Fw3vy9vRv The table could look like this and you mount the pole on one of the corners. (the table would obviously be bigger). Figured I would share the idea for anyone who wants a blocker. What do ya' think? |

However, this changes when you start looking at it from a ranking perspective rather than a winning perspective. Take, for example, years where your second sort was based off of your opponent's score. During those years it was beneficial to allow your opponents to score so long as you could outscore them. So, what I'm saying is that offense or defense wins matches (it doesn't matter which one) but offense tends to rank higher. Now, the really fun part of the discussion involves the difficulty and risk of effective defense as well as the metagame of the area you are playing. You also need to take into account the difference between effective defense and crappy defense (I'll give you a hint 90% of defense is of the crappy variety, maybe more). |

If a robot is able to effectively seal off one side of the field (or simply deflect even as low as 25% of shots) it doesn't matter how far you can shoot, or how well you can catch, if you struggle to end a cycle, even mediocre robots will take the banner away from you. Points not being awarded to your opponent are subtly points being added to your own score. If you can slow down the other alliance such that they can only complete one less cycle per match, that effectively gives you an entire cycle's points worth of a head-start on them. Matches are only ~2 minutes long, and when your 20fps shooter fires a ball right into the awaiting goalie post of the other robot, it is going to go flying in some direction, wasting precious seconds. If a defensive bot can deflect even as low as 2 shots per match, I wholeheartedly believe that they will significantly hinder your score. Also take it psychologically: from a driver perspective (as a former driver), getting your shots blocked is very frustrating, in the heat of a match nothing makes you madder than an effective defensive robot hindering your progress. As you get angry you stop thinking clearly, only digging yourself deeper. Even the most trained and level-headed drivers will face the pressure of constantly being shut down. This makes me wish we had made a defensive bot this year. |
