Ultimate Ascent - Most Difficult Ever? Too difficult?
This is my 12th year in FIRST Robotics, and I'd thought the build had generally become somewhat routine, the games somewhat predicable, and I'd just about seen it all. But now in the third week of build season, I'm finding this very difficult. Even with the ability to rapidly make parts in-house and over a decade of experience of doing this, I'm finding myself doubting our abilities to get it all done by the deadline, and do everything well in this game, and keep the robot built to our standards of quality.
Over 2 weeks in and here's where we are: Accurate prototype shooter. Full welded steel pyramid about 90% constructed. One goal and one feeder station constructed All sprockets, bearing blocks, chain tensioners, and wheel axles machined Gearbox designed Prototype intake Electronics mostly laid out, and wire routing planned Base chassis mostly designed. Still need to design base pan. Here's what scares me: The climbing mechanism has not yet been designed for real in CAD Neither has the shooter Nor has the intake conveyor Nor has the feeding mechanism Nor has the storage area. There are areas of our robot that could experience 600 lbs of force under certain circumstances. All of the above I can see taking another full week to design. And the really scary part, is I can envision a week straight of welding for 4 hours every night being necessary. Fitting all this stuff into the new 112" frame perimeter has been a nightmare and a half. And I know there are others with more years in FIRST than myself who have mentioned the same difficulties. If those of us with this much experience are having this much trouble with it, I fear for what the game will look like for teams of average standing. The teams who work out of a classroom or meet less than 20 hours per week are really going to struggle. Is this the year one robot/team just can't realistically do it all? Is combining the challenging game with the reduced size just too much to ask? Is there any wayto be competitive at this without meeting every single day until midnight. I've poured every neuron in my brain and dollar in my wallet into this over the past two weeks, and it doesn't seem any easier yet. I think a lot of teams will really struggle this year, unless they decide to abandon any plans for hanging beyond 10 pts. The 20 and 30 point hangs will be very rare, especially for a robot that also shoots well. Kudos to FIRST for really switching it up, but I feel this year has just taken a littletoo big of a step, to the point where the key members of a team are required to sideline the rest of their lives to be truly competitive in this sport. As a teacher, on top of my full time job, I've put in over 45 hours per week over each of the last two weeks (and so have some students) outside of the school day, and we're still behind. Being a real leader in this sport is a full time job, which is a lot on top of an already full time job. I'm not saying I want an easier challenge, but if after 12 years and almost all the resources we could need, me finding it difficult makes me think it's terrifying if not impossible for many teams to do well in this year's game. Anyone agree with any of the above? |

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
Difficult? Yeah.
Extremely difficult? Some parts. Doable? It's been done. It's being done. This game is hard, hardest I've experienced, but it's completely doable. I think with this game teams had to cut down on their priorities and focus on doing a select few things really well instead of everything. As stated in one of the many 1114 white paper resources that I've read 1000 times, "If I had 30 unites of robot, I'd rather have 3 units of 10 rather than 6 unites of 5". While some very good teams in previous years could do everything and more with 10 units of robot, I think due to this year's challenges even all-star teams are cutting back on doing everything and focusing on being able to do a few things really well. That being said, I still know a lot of people who are trying to do everything imaginable, and may succeed at it. Maybe you'll figure something out before the build season is over and make a kick-butt do everything robot. But on the off-chance you don't have an epiphany anytime soon, I think it would be a good idea to start focusing in on a few major priorities for your strategy, and once those are done look into making them better, and MAYBE after that look into adding those things you couldn't fit into the build season. There are 3 weeks left. You're not alone. Most teams are behind schedule this year, ourselves included (we'll be cutting steel tomorrow for the first time). Make the best out of the time you have left, and make sure what you get at the end of it does whatever it does at 110% power. |

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
This year is super tough, and I love it! We are going for everything, and I'm very optimistic.
There will be very few robots that can do everything, but teams that specialize in a certain aspect of the game will do very well. I think the GDC did an excellent job with the game design this year, and we'll have some exciting gameplay. |

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
This is my 11th year, and this is definitely the hardest game to do everything in. There will be teams that do it. There are a lot of curve balls, but for most of the elite teams they are working on a 16 week build schedule anyway. By the time championship roles around we'll see some very impressive robots.
The new size requirements seem to make robots lighter. So even though we are putting climbing on hold, we have a few ideas of how we might be able to do it before Championship if were able to get there. |

Here's my opinion on making the typical powerhouse "do everything" robot. It can be done. But it won't. Not successfully. By do everything, I mean have a half court shooter and a pickup and a 30pt climber. There simply is not enough room on the robot to fit on all three without heavily compromising multiple aspects of the design. Maybe there's some game breaking design that I just haven't come up with, but I just don't think it's possible. Any team that tries will underdesign their robot to the degree that it will fail in competition. We're managing to do 2 (or 1 1/2, depending on how you look at it) out of three. If we can pull it off, it will be a beastly robot. But if a mechanism breaks or fails to function as designed or we don't manufacture fast enough or if software doesn't work or if it's too hard to drive or if it breaks in competition it will be a failure. High risk and high reward. A 30 pt is the hardest thing I have ever designed (and you should have seen our off season project...). We have a huge leg up, a very good prototype climber, but there is still a chance we will fail. Fitting it into that smaller frame size compounds the challenge. Here's what I can take away: you don't need to do everything. I know a few people on very successful teams, and they won't be trying to do everything. This year will go down in FRC history as the hardest one ever. The robots that rise to the top will not be the ones that do everything poorly, but the ones that are breathtaking at one thing. Be that robot. |

Has FIRST ever made a game that was easy to do?

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
This is my 9th season. I agree that the combination of game mechanics and robot constraints have made this game a designer's nightmare.
It has kept me up until 11pm and woke me at 6am most weekdays. I spent 24 hours in 3 days just coming up with a side & top profile sketch of the inner workings of our bot. The student CAD'ing the disc launcher isn't losing sleep, but is definitely stressed given the amount of work we're putting into CAD this year. Packing it into a smaller frame and (oh yea) under 27.5" is even worse. Yet we're through the hard part now. Keep pushing, you'll find the same! |

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
I think this is the most true-to-life game in my FIRST history. I feel the GDC did a great job with this year's game, especially with the introduction of a new game piece and new robot size requirements.
The scoring objectives are not necessarily clear to which is most valuable. This game is all about developing game level objectives (how to play the game), setting priorities, determining trade space, and sacrificing methodology or mechanisms for the sake of achieving your team's gameplay objectives. In my workplace, I work with extremely complex systems that in many cases are supposed to "do it all". This game is a prime example of how these systems are conceived and developed. |

Yes. 2008 and 2011 had extremely simple tasks that were required to score points. 2011 being 4 years after the previous tube game, with a behind the design book being available every team should have been able to score 2-3 tubes a match. From my point of view 2010 was harder. the three challenges of the bump, possesing the ball and hanging that year were harder as a combined group. The low hanging fruit way to play this year, human loading, dumping then doing a 10 point hang will be viable for most teams and seed at most events. The robot that does everything may not actually be viable this year due to space connstraints. It also may not be necessary. To me this is like 2004 where it was almost impossible to hang, hold the doubler ball and collect small balls on 1 robot. In the end only the best teams did it all, while other teams figured out one of those tasks was unnecessary if you played the right way. *Disclaimer: I'm not heavily involved this year, after 11 years I have too much going on this year to spend much time with the team.

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
This is year 9 for me. This is by far the most fun; oddly, the challenge seems much more doable for us this year. Not because the game is easy or because we've found the secret for a do-all bot; rather, because we accepted early on that we could pursue one of several viable scoring/utility options, and that by excelling in that narrow band we might have a chance in our region. I think lower tier teams that think through their options could become valuable and viable players. Not everyone will like that, and I'm sure the powerhouses will still do everything well, but I am excited to see what teams come up with this year.

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
This game definitely seems to have been designed to force teams to compromise. Want an accurate shooter? Floor pickup? Storage and indexing for 4 discs? 30 point hanger? Pyramid goal scorer? Go under the low rung of the pyramid? Here, have a 112" frame perimeter and a 54" cylinder (oh, and your bumpers count too).
If you refuse to come to any compromises with your Ultimate Ascent robot design, you risk compromising everything (including your sanity). |

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
The more I read about the difficulties everyone is having, the happier I am my team said on day 1, for the first time in team history, that we weren't going to be doing everything.

Re: Ultimate Ascent - Most Difficult Ever? Too difficult?
You are not alone, this one's tough.
Our initial strategy to climb for 30 and dump four for 20 more points was near unanimous by the team, and it looks like a lot of other on CD had the same idea. We knew we could only focus on one thing, we didn't have the resources to try to do it all, and were blinding by the big score. Two weeks later we realize just how hard, and how big a risk that strategy is, and two weeks have been lost. Yesterday we scrapped all we had done prototyping and CADding a promising climbing mechanism and will be starting from square one with a shooter and a 10-point climb. The main concern was finishing in time to get some driver practice. The design challenge was considerable, requiring a unique chassis, and we weren't even trying to incorporate a good shooter. Now we're hopeful to get a working, playing robot done before ship day, instead of machining like madmen trying to finish an unproven climbing mechanism by Tuesday night. Bite off what you can chew I think is the lesson for this year. |
