Robot in 3 Days Robot Reveals
 

I can't believe we made it! The 72 hours is now complete and all 4 robot reveal videos are now posted on YouTube for your viewing pleasure. Remember, 3 Day robots are about inspiration not information. Take what you can from our Robots, learn from them and go forth and do better! After seeing what we could do in 3 days I can't wait to see you can do in 6 weeks.

Check out the playlist of the 4 builds here.

Voting is active now! Robotin3Days.Com/VoteNow

We'll have our judging panel via Google Hangout on Wednesday, January 8th at 8pm. Tune in tomorrow to hear what our judges Benge Ambrogi, Vincent Wilczynski, Dave Verbrugge, Andy Grady and Jessica Boucher think.

Reveal video views, votes and judges scores will be summed and the winner will be announced Saturday at 8pm!

Thanks for watching, this has been a lot of fun!

Re: Robot in 3 Days Robot Reveals
 

Did I see that wrong, or do you flip off the camera at 4:38?

Re: Robot in 3 Days Robot Reveals
 

cutting sign.....like cut, we're done

EDIT: The lighting seemed really bad for that scene

Re: Robot in 3 Days Robot Reveals
 

I really like team Boom Done.'s pickup mechanism and 8 motor drivetrain. Out of all of Ri3d and Build Blitz they definitey have the most unique robot.

Re: Robot in 3 Days Robot Reveals
 

In the rules it states how nothing can extend outside of the robot perimeter during the start of the match. I think some of these robots have appendages that start outside the robot.(Correct me if I am wrong) Other than that great job to the teams that participated.

Re: Robot in 3 Days Robot Reveals
 

I really liked Ri3D's bot. Simple, to the point, good launcher.

Boom Done was my second favorite, liked the chopsticks, and the 8 motor drive train.

Re: Robot in 3 Days Robot Reveals
 

The acquisition on Boom Done. starts upright and then flops down right away. There is no power to it but it rests upright until they move I think. O-Ryon can start with their claw pointing up and it fits I believe. I'm assumind Ri3D 1.0 would start with the catapult in the "fired" position and the acquisition straight up and the ball resting on top. They would have to open up first before firing, but it could work.

Re: Robot in 3 Days Robot Reveals
 

Now the GDC can issue a rule change that will make some of what they did invalid, like adding a End Game that can not be added to any of these bots. I will admit that these look very good, but am not sure that putting out something like this for teams to copy is how we need to be approaching this.

Re: Robot in 3 Days Robot Reveals
 

The engineering design process is a series of steps that engineering teams use to.
I hope your aim is to Encouragement

Re: Robot in 3 Days Robot Reveals
 

You conspiracy theorists are getting on my nerves.

Re: Robot in 3 Days Robot Reveals
 

:deadhorse: Oh...are we starting this again?

It's such a shame that now there will be video online showing teams how to pick up a large inflatable ball and throw it over a bar...

These are meant to inspire teams and give them a theoretical starting point so that they might improve on the ideas showcased and ultimately build a more competitive robot. Much like the people who built the Space Shuttle took the ideas used in Mercury, Gemini, and Apollo and applied them to their own design process.

Re: Robot in 3 Days Robot Reveals
 

Yes! Well said. Teams are also using help from 2008. Just like how teams in 2012 referred to 2006. and 2011 to 2007.

Re: Robot in 3 Days Robot Reveals
 

O-RYON obviously had more time then they needed because they had more lights then a Christmas tree in New York Times Square on Christmas eve

Re: Robot in 3 Days Robot Reveals
 

I cant seem to find the reveal videos online, if someone woulnt mind posting a link.....that would be much appreciated, thank you.

Re: Robot in 3 Days Robot Reveals
 

There is a link to all of the videos in the first post

Re: Robot in 3 Days Robot Reveals
 

Somehow I think the organization that promotes coopertition and collaboration is not going to design their game around the destruction of a valuable resource to teams. And even if they do defy their own principles, Ri3d will most likely design a hanging system and show that to teams. What is the GDC going to do then, add more end game objectives?

Re: Robot in 3 Days Robot Reveals
 

I was honestly most impressed with Team O-Ryon(spelling?)'s robot. It played all aspects of the game relatively well, and excelled at most. Strong drive and pickup, scored 1 pointers easily, could truss shot and 10 point shot (from up close) and catch if the pass was on target. Not to mention one hell of a lights display. I think they clearly took a more innovative path than the simple roller and catapult design. Add a simple goalie stick to their robot and they could do everything in this game.

Re: Robot in 3 Days Robot Reveals
 

Agreed. O-Ryon won this challenge. This "point guard" bot could rank very high by their ability to quickly possess the ball and drop it off for an assist. Getting a one point shot near game's end is defintely less risky than missing a high shot that rebounds toward mid field.

Very impressive.

Re: Robot in 3 Days Robot Reveals
 

While i voted ri3d 1.0 for what seemed like the most consistent robot there, I really liked BOOM. DONE.'s unique intake idea and their catapult system was quite different from the others'. Their meccanum drive train was also something that the others didn't do, and i'd love to see if it helps with their unique intake.

Re: Robot in 3 Days Robot Reveals
 

Can't you only have 6 CIM's on the robot? Why do some of the robots have 8 CIM's in their drive base?

Re: Robot in 3 Days Robot Reveals
 

They had 4 cims and 4 mini cims. You can have a total of 6 cims and 4 mini cims on the robot.

Re: Robot in 3 Days Robot Reveals
 

These crews built their robots with the intention of not sticking to the rule limitations. If you noticed, they used illegal electronics too.

Re: Robot in 3 Days Robot Reveals
 

4 CIMs
4 Mini CIMs

Re: Robot in 3 Days Robot Reveals
 

Thanks for doing this again! I learned so much from these and I have shared it with both of the teams I work with.
The day 3 interviews made me laugh. RI3D 1.0 looks ready for RI2D.

Re: Robot in 3 Days Robot Reveals
 

What are you talking about? They specifically state in their videos that they use all completely FRC legal parts, and follow all the rules... What is the point of doing this if they break the rules?

If you are being sarcastic, well, don't. Text is a horrible medium for bad sarcasm.

Re: Robot in 3 Days Robot Reveals
 

Boom Done got my vote, with team O-RYON with a very close 2nd.

Really awesome job by all teams. I only wish Indiana wasn't in a state of emergency so we could see the final version of AndyMark's cam launcher.

Between these four teams and the VEXPro Build Blitz, you all have helped so many teams so far.

Thank you for your long hours in order to put these robots together!

Re: Robot in 3 Days Robot Reveals
 

I for one think these robots should play some matches together at IRI or another off season event to really put them though their paces. So with the exception of AndyMark for an extra day, none of the other five should touch their robots until then.

Re: Robot in 3 Days Robot Reveals
 

Not only have these three/four robots served a great service to the community in terms of process and specific designs, but I wonder if Boom Done stumbled upon a way to recruit/train new mentors. According to one of the interviews, nearly all of Boom Done had no FIRST experience before Saturday. I would think having a super intense 3 day build season with a legendary FIRST mentor would be pretty inspiring and serve as an invaluable FIRST training for a professional engineer. I'd be curious to hear if any of their team decides to mentor a FIRST team after their three day build season.

Re: Robot in 3 Days Robot Reveals
 

I should have been clearer.

Mechanically speaking, most, if not all, of the parts are legal and designed for implementation on FRC bots.

If you noticed though in Ri3D 1.0, they used a Sasquatch robot controller as their primary device for robot control, which is not allowed in the rules. They also used illegal electronics on last year's bot as well.

Anyway, this really isn't too relevant, as the mechanical designs and their implementations are perfectly legal.

Re: Robot in 3 Days Robot Reveals
 

I think team Ri3D 1.0 would love to play a match against the other teams. But in the spirit of Gracious Proffesionalism we'd really hate to embarrass them when our robot shows them up. #OhSnapNoHeDidnt

/edit As some people tend to be very literal, this post was meant to be taken in jest. And that the other teams may see this and they in turn would "throw down." Thus ending in a match sometime in the off season.

Re: Robot in 3 Days Robot Reveals
 

I'd like to see AndyMark's finished robot. I doubt they'll be able to (they probably have other commitments)

Re: Robot in 3 Days Robot Reveals
 

Challenge Accepted!!

Team O-Ryon would love for that. We'd say give AndyMark an extra 24 hours or so to finish their robot and some time for everyone to make bumpers and we all could meet up for a friendly competition.

Re: Robot in 3 Days Robot Reveals
 

Since 3 of the 72 hour robots were built in Texas it seems only fair that we should host this event. :) Texas Robot Round-Up in August or Robot Remix in Oct/Nov?

IRI would be acceptable as well.

Re: Robot in 3 Days Robot Reveals
 

Stop. This is an "if pigs had wings, they could fly" type statement.

Could the GDC reverse field and add an End Game? Yes, they would be within there "rights" as a GDC. Are they going to? NO! The GDC is not going to add an End Game. It is not going to happen.

Don't waste time and energy on things that are very very very very VERY unlike and also impossible to plan for anyway because there is always going to be SOME End Game that will make ANY design choice the wrong one.

Move on.

Joe J

Re: Robot in 3 Days Robot Reveals
 

BOOM DONE.'s goal was to build a robot that could pass inspection. The only violation I know of is the indicator light that the field uses to tell the status of the CRIO. Other than that, I think we could pass inspection.

Joe J.

Re: Robot in 3 Days Robot Reveals
 

All of these entries were very impressive. I really like these videos as they give you an idea of how a completed robot interacts with the field and game pieces early on in the season and makes planning for strategy a little less hand wavy.

Thank you to the teams for all of the hard work that you've put in over the past 3 days. You are doing a ton to help the community and inspire both students and other mentors. Keep fighting the good fight!

Re: Robot in 3 Days Robot Reveals
 

+1! And by the way, Dr. Joe, what tape/wrap did you use on your acquisition wands (torro sticks)?

Re: Robot in 3 Days Robot Reveals
 

Good job all of you, very impressive!
This will help a lot of teams head in a productive direction.

Not necessarily copy a design, but inspire them to think of somthing they hadn't considered.

Cheers to Ri3D teams

Re: Robot in 3 Days Robot Reveals
 

Sorry you don't agree with my opinion on this. But it has not changed and based on posts in previous threads that I had not read prior to today, I am not the only one. However if this type of thing helps even one team then you got what you were going for. Cad drawings and a BOM will be even more helpful for teams.

Re: Robot in 3 Days Robot Reveals
 

Glad I was wrong, rewatched on my computer (originally on phone) and I can just see that 2nd finger.

Re: Robot in 3 Days Robot Reveals
 

More details to come but the best stuff I know for this kind of task is Abrasion-Resistant Natural Latex Rubber from McMaster

I like the 1/16th thick rough on one side stuff (86085K2)

Again, more details to come.

Joe J.

Re: Robot in 3 Days Robot Reveals
 

While we at Team AndyMark chose not to complete our Robot in 3 Days, we did get much CAD completed.

Here is a .STEP file and a Solidworks Pack and Go .zip file for folks to see.

At this point at AndyMark, our main focus is to support our customer base and keep operations humming. We also work with some local FRC teams, and those teams will be helping us complete and test some of our prototypes and designs. However, we aren't going to force the students to use the designs we made during Ri3D. Due to weather, the students have not been able to decide upon an overall concept. Hopefully, our design work may be able to help them come to a conclusion.

Sincerely,
Andy Baker

Re: Robot in 3 Days Robot Reveals
 

Count me among the people who'd love to see:

A) Team AndyMark's robot finished, regardless of how much extra time they need.
B) All 6 72-hour robots (Ri3D 1.0, AndyMark, Boom.Done., O-RYON, TeamJVN, and TeamCopioli) in one place, with a field, playing a MATCH (or possibly a small tournament) of Aerial Assist, before the end of build season.

Re: Robot in 3 Days Robot Reveals
 

Great idea, or somthing like that, maybe some mock matches with mock officials that know the rules, robots and teams to play out real scenarios.
It would be great to watch some actual matches play out, this would help teams figure out what will actually happen at competitons without learning the hard way.

How many times have we said "hey I didn't forsee that happening" or "you can do that?" :ahh:

Re: Robot in 3 Days Robot Reveals
 

Will this actually be a FRC's teams competition robot?

Re: Robot in 3 Days Robot Reveals
 

Even though it's completely impossible. I think It would be really cool to see these robots compete in an actual regional. It would be interesting to see how they size up against what everyone else builds this year.

Re: Robot in 3 Days Robot Reveals
 

No. I love it way too much to risk letting some high school kid drive it like he stole it ;-)

Joe J

Re: Robot in 3 Days Robot Reveals
 

haha.

Have you tried other materials for the intake system? A very popular sticky item back in 2010 was Dycem, I even pushed to use it on our floor intake last year.

Re: Robot in 3 Days Robot Reveals
 

Thanks Dan.

Would it be possible to provide a version of the Ri3D1.0 video with subtitles? Or maybe just a version with the background music completely muted when people are speaking? Their voices are muffled and I cannot understand what they are saying. Thank you.

Re: Robot in 3 Days Robot Reveals
 

Those are some pretty impressive robots. Is it true that nearly every team will be releasing their schematics and code for their robots? And if so anybody find any crucial flaws that would be difficult to overcome during a regional. I would love to talk through some of these designs with my team.

Re: Robot in 3 Days Robot Reveals
 

Dr Joe,

1) Can you also quickly comment on the Versa planetary gear ratio you used on the torro sticks and I'm thinking about ordering those today.

BTW, the motor/chain powered launch mechanism is leading me away from a winch/catapult style design for my team.

Regards,

Marc Center, FRC3548 coach

Re: Robot in 3 Days Robot Reveals
 

Dr Joe,

Out of curiosity, how did you fasten the "toro sticks" to the Versa planetary output shafts? What material are they?

Re: Robot in 3 Days Robot Reveals
 

Toro Horns. Schedule 80 PVC (thicker wall than Schedule 40). I heated up some 1/2" hex shaft and melted it in place so that a Versaplanetary shaft fits tight inside.

Very happy with the result.

Dr. Joe

Re: Robot in 3 Days Robot Reveals
 

The VersaPlanetary set up is this:

• Banebot 18V motor as input (crazy overkill but when you are building a robot in 3 days you use what you have in hand and once you find a thing that works, you don't change it unless you have to).
• 4:1 stage 1
• 5:1 stage 2
• 1/2 hex output.

I love the versaplanetary system. I think they are a huge help to teams prototyping because it is so easy to change the motor or the ratio or the output shaft. I've got no financial stake in the product or company, I recommend buying a boatload of ratios and output styles (1/2" hex and 1/2" round are my preference).

Calling 'em like I see 'em.

Dr. Joe

Re: Robot in 3 Days Robot Reveals
 

Dr Joe,

Thanks for your answer.

Sticky material (dycem?) from a previous post (Alex Cormier) found can be found at andymark here http://www.andymark.com/product-p/am-2454.htm

This may be a suitable substitute for the natural latex rubber product you used from McMaster-Carr, but needs testing for confirmation.

Regards,

Marc Center

Re: Robot in 3 Days Robot Reveals
 

I agree with Andy Grady on the judging show: El Torro will be the single most copied mechanism this year. To all the teams participating, good job, and thank you all for your time and effort.

Dr. Joe, if it's as planned, we may have a robot named after you (we have a tradition of naming robots after people) :)

Re: Robot in 3 Days Robot Reveals
 

Thanks for the feedback Either! We were dissappointed with the audio quality during that take, but did not notice it until editing. We will do our best to get some annotations in. In the mean time we will do a complete rundown of the robot. May be long and boring but we hope it to be informative. We have quite a few important features that need to be highlighted.

Thanks,

Dan

Re: Robot in 3 Days Robot Reveals
 

Thank you!

This does not sound the least bit boring to me! What you've described above will be an excellent teaching tool. It sounds somewhat like Joe Johnson's video, which was the most informative and helpful of the 4 posted.

Re: Robot in 3 Days Robot Reveals
 

Our team is working on a prototype of the catapult system used, our question is what are they using to pull back the arm on team JVN? What is the black material shown in the picture attached? :confused:

Re: Robot in 3 Days Robot Reveals
 

It is surgical tubing.

http://www.mcmaster.com/#surgical-tubing/=q6g64z

Re: Robot in 3 Days Robot Reveals
 

That was to say, very little editing, snappy music etc... Joe's video may have been simple but it was very well produced AND any time Joe speaks, something interesting is said! :-) I hope to have something by Saturday.

I've also uploaded rev1 of our winch gearbox to the Robotin3Days.com blog. There is some missing info and minor differences between this version and ours. Most namely on our bot we trimmed down the dog and gears and in this version I left them untrimmed. The intent is to get closer to an off the shelf solution for teams. The only custom part is the shaft which AndyMark has agreed to carry and should be available sometime next week.

Re: Robot in 3 Days Robot Reveals
 

This is true. We stayed with our original intent of the challenge: To demonstrate a mostly FIRST legal robot, utilizing efficient prototyping process, tools and techniques. We also were committed to having our systems completed and not left in unfinished state. If it weren't going to be able to implement it in time, it didn't go on the robot.

We believe strongly that if teams focus on finishing early and allowing their drive teams and programmers time with the bot they will see significant competitive advantage at their first regional. Most teams only see 1 regional, so this is a huge must for them. Teams that show up Thursday morning ready to pass inspection and practice immediately will have competitive advantage early on, unless they have the resources i.e. 2 robots or multiple Regionals to compensate for this lost time. Our team saw the equivalent of 2 weeks worth of driver practice and test and adjust utilizing these principles.

(This obviously doesn't count for rule binding things like bumpers etc... Make sure you read the rules...)

Team Ri3D has also released a 75% CAD of their intake mechanism here: http://www.robotin3days.com/ri3d-1-0-roller-intake-cad/

Team Boom Done posted the CAD of their robot as well here: http://www.robotin3days.com/team-boo...-capabilities/
