Couple questions. 1. Why did you opt for dual flywheel launching and what rpm are your wheels? 2. Why only store 2 rings, was it just lack of space/resources? 3. How fast are you running your rollers and conveyor? 4. Why did you intake into the opposite side you launch from? That’s kinda it, but this is a very cool bot as always. Thank you guys for doing this every year!
1. Either a double or single flywheel would work great, we just went with a double flywheel because we could get enough speed from two Neverest 3.7's instead of spending the time to build a gearbox for a single flywheel. The wheels are just mounted directly to the Neverest 3.7's, so they're running at about 1780 rpm. 2. Yeah, we wanted a very simple feeding mechanism so we kept it to two. I'm sure teams can come up with some cool ways of storing 3 though! 3. They are all powered 1:1 off a Neverest 20 at 340 rpm Thanks, hope that helps!
Oh, that's cool that youtube recommendations are picking it up. This is First Tech Challenge, a robotics competition to design and compete with these sorts of robots.
Great work guys. Just wondering what you used to create the rings. At a school in Australia and really can't afford the 80USD to ship a set of rings over here.
Thanks! We were able to calculate the density of the foam based on the CAD file and weight estimation from AndyMark, and it seems likely the actual rings are made from a lightweight foam with a colored coating. Then we managed to dig up some kneeling pads (similar to this: www.amazon.com/dp/B01NAYS8KN/ref=nav_timeline_asin?_encoding=UTF8&psc=1) that seemed like the right kind of foam and cut them into the ring shape. You might have to get creative with what you use, but hopefully that helps!
I have a question. How did y'all change the trajectory of the rings to shoot in the mid and high goals? Is it different rpm, or a servo changing the angle of the shooter? Thanks for doing this every season-Team 15308
I don't think this version purposely changes trajectories. I believe they were aiming for the high goal the whole time but often missed it into the middle goal.
@@AmazingSpanoMan You probably need to eliminate warping in your drivetrain then. Are you running on the foam mats? That will also affect how well you strafe. What sort of wheels are you using? I would stay away from the old tetrix ones if I were you.
@@johnathanclayton2887 we are using the AndyMark tile runner kit with their Mech Wheels. We are running on 5he foam tiles for our testing. I'm thinking the platform is built so we'll there is no flex which actually is helpful for keeping the wheels planted. We always seem to have one wheel that isn't making food contact which kills our strafe.
@@AmazingSpanoMan Weird. I would think the tile runner would have a tight enough tolerance to keep all wheels on the ground at once. I would perhaps loosen your screws, try to push all the wheels onto the ground, and then tighten back up. But probably call Andymark, since it might be that the holes in the plates on that particular tile runner were out of place. Also, looks like the default wheels that come with the tile runner are the annoying standard tetrix compatible ones, not the nicer HD ones. If you want to improve strafing over time once you get all the wheels to touch the ground, I would recommend switching to HD or GoBuilda mecanums if you want to go with mecanums and you have enough money.
We guestimated the kind of foam based on the density from AndyMark. We ended up using some kneeling pads (similar to this: www.amazon.com/dp/B01NAYS8KN/ref=nav_timeline_asin?_encoding=UTF8&psc=1) that seemed like the right kind of foam and cut them into the ring shape. I don't know the exact weight, but it should have been pretty close, or maybe a little heavier than that. Hope that helps!
hey few questions: 1.) Does this meet the weight requirement? 2.) How did you deal with the weight of the motors? Also cool design! Kinda inspired what we imagined with ours! Keep it up!
What do you mean base length? I think the robot is pretty much 18 inches long without the collection deployed, and I think that adds another 4 or 5 inches to the length when it folds down.
Yeah, because you don't have to be behind the line to score into the low goal we can just drive right up to it and shoot in. The higher goals are much more worth it though!
@Alkali I don't think they are those, because at 0:06 and 1:17 you can see that they don't have the wavy pattern that the gobuilda ones have. Looks like they are the black compliant wheels with a tetrix hole pattern from Andymark.
how in the hell did yall build a robot in under a week of the announcement?!?!?!?! Cheaters confirmed? yall knew the rules before all us, RIGGED!!!!!!!!
Once again, you guys have broken the spirit of gracious professionalism and built a solution to the game before any of the FTC kids have had the chance to get started. Ask yourself "What would Woody do?" (hint: not this) -> What does it prove? That you're smart? You guys had your time in the league, now it's time to move on. You guys take all of the fun out of the season for the students when you build and promote a video like this. Let the students have their competition. You guys are ready for the big leagues, go get an internship at a real robot company and leave the FIRST robot building to this seasons participants. OR become mentors OR host an open forum to answer engineering questions OR comment on the build videos produced by the (student) teams OR become referees/judges OR volunteer to help run a competition. Offer answers to their questions, don't give them the answer.
Hi Mike. I think that this is totally within the spirit of gracious professionalism. I'm trying to lead a group of relatively inexperienced students these videos are invaluable in giving them initial ideas. I am grateful that these guys have shared their experience for those of us still trying to develop our skills.
You commented pretty much the exact thing last year, so I'll just copy the top replies from last year: "The thing about these designs is that they are never the best option for the games. They may be heading down the right path but you can't win a higher level competiton with these designs, they're only helpful in proof of concept. I think it sparks imagination and inspiration in students to see that these kind of robots can be achieved in such short amounts of time" "I understand your point, but for the many teams that struggle to find any mentors except perhaps the one teacher willing to give their time to the team but lacks skills themself, where would you point them today? Early season reveal videos are a great resource for young and experienced teams alike to build IDEAS, not build clones. But even if they clone the idea, they still have some level of design, fabrication, and programming to do, and they learn a lot along the way. Individuals from the vendors also do prototyping and strategy videos, and are very well received by all I talk to." "@Mike Oitzman I was a mentor on this team when both these gentlemen were students. Both gave up a weekend of study time from college to hit the team garage and build because a) they love what the FIRST community enabled for them and love to build robots and b) they know what they release will be helpful to the community at large. Neither of them has a hint of ego, and your comment is out of line." "I can confirm that these two are among the best people I know. They in fact have mentored us hands off extensively throughout last two seasons and exactly like you said they should do instead. I don't think these two forms of help are mutually exclusive. Both forms are helpful for teams. Neither is simply handing the team solutions, and in both cases, learning is facilitated better through the help." "I disagree. As a veteran mentor and engineer, I think these early builds give a lot of insight into pros and cons, and also get the kids thinking. They get introduced to advanced engineering designs, and they often take on the responsibility of learning them. There are also many pros and cons to these builds; I can already think of a few issues and limitations from looking at this one. It is always beneficial to be able to see those limitations first hand without having to go through the process of building it. And let's be honest; it is exactly how we adult engineers learn!"
@@DamienMurtagh-Galea I am sorry. I stand firm in my belief that these types of builds only serve the egos of the builders. I 100% support STUDENT led early builds/shares/reveals. The number one principle of gracious professionalism is to let the kids do the work, and this is the foundation of FIRST. No doubt these guys are passionate about building robots and helping the students learn. I am not questioning that. I just calling out the fact that they are putting their "thumbs on the scale" when they shouldn't be. A better use of their time would be to go back and critique student designs from past years and compile a video of all of the potential features that could be adapted to this years challenge.
@@johnathanclayton2887 I don't know of any team that starts their season with the mentors building a solution to the challenge as a method to enlighten the kids about how to solve the challenge. That's exactly what this is.

What parts did you guys use to create this monstrosity
Where did you get the pully and belts from. Thats on your intake and on the ramp.
Looks like the pullies and belts on the intake are from actobotics. They are the smooth hub pulley I think. The O rings are from actobotics as well.
Here is a link to the product page: www.servocity.com/1-00-od-0-500-id-smooth-hub-pulley/
how did u make your intake stay upright but still come down without the ground
Imagine having access to your shop
What was the diameter of the gray wheels used for the intake?
I'm pretty sure those are 2" wheels.
How did you get the rings up the robot. It's super smooth and I can see 2 thin black lines but I can't tell what they are.
Nevermind I'm pretty sure it's a belt based on the shot at 0:07
Yep! We actually used rubber bands for the belts since we didn't have anything that fit well enough, but they worked pretty well
@@Robotin30Hours what are different size of belt used ?
We are having such a hard time getting out mech drive to strafe consistently any suggestions??

whats the shooter angle

Nice!
Did you guys check the distance on the launcher to make sure isn't doesn't exceed the power limit specified in the game manual?
hey few questions:
1.) Does this meet the weight requirement?
2.) How did you deal with the weight of the motors?
Also cool design! Kinda inspired what we imagined with ours!
Keep it up!
What angle is your guys outake wheels at?
Hey what motors are you using for your shooter system?
What is your base length. My team is debating on whether we should use a similar system or not to.
What do you mean base length? I think the robot is pretty much 18 inches long without the collection deployed, and I think that adds another 4 or 5 inches to the length when it folds down.
@@johnathanclayton2887 what I mean is what is the robots base dimensions with out any attachments.... Is it 18in or shorter
