Robot in 3 Days : Completed Robot Video
 

Wow we made it! Just uploaded the Final unveil video of this crazy journey. I'm not gonna lie, I got a little emotional editing this video wrapping up the last few days. (And months really that we spent preparing for this)

In this video you will see all the systems in our bot, fully functioning under control. Including the climbing mechanism everyone has be chomping at the bit to see. Also the shooter making shot after shot, we found our sweet spot about 15' out. (You wont see Robby, he was back in the "real" world making flying cars.)

We hope that teams see these videos then go out and take what we have learned, apply it and make better, more competitive robots.

Big thanks to 1902 Exploding bacon who brought us their innovative 3-in-1 (could be 4-in-1) goal, which has high, medium goals and a loader station in one portable design (look for drawings some time soon, but you can figure it out)

Keep Calm and Robot on!

Re: Robot in 3 Days : Completed Robot Video
 

Awesome bot! I could see it ranking near the top at some regionals. I'm not sure your lifting mechanism is entirely legal, though, as the top of the claw partially occupies level 2, putting you in 3 levels at once.

Re: Robot in 3 Days : Completed Robot Video
 

It's only a problem if it touches the level 2 parts of the pyramid.

Emphasis mine.

Re: Robot in 3 Days : Completed Robot Video
 

Air is not considered zones; literally touching the second bar is constituted zone 2. If just being over the first bar is zone 2, how does a team hang in zone 1?

Re: Robot in 3 Days : Completed Robot Video
 

it's legal because its not touching part of the pyramid that's in level 2. you can occupy as many levels as you choose at the same time but you can't contact the pyramid in more than 2 levels at once.

but yes amazing work guys.

Re: Robot in 3 Days : Completed Robot Video
 

Thanks so much guys! Your videos will definitely be part of tonight's meeting!

Re: Robot in 3 Days : Completed Robot Video
 

You were reaching your fingers through the loading slot, which isn't allowed.

Re: Robot in 3 Days : Completed Robot Video
 

Beautiful robot for such a short time span! Especially enjoyed the part with cute baby. Hopefully teams can take what you learned to make their build seasons better.

One question, I know you shot frisbees upside down in an earlier video, but now that it's complete, did you shoot any of them at the goal upside down, if so was it successful or not?

Thanks for all your hard work! I'm sure many were inspired!

Re: Robot in 3 Days : Completed Robot Video
 

If I were Car Nack my first prediction would be that robot in 3 days would seed higher than 80% of teams at any given regional.

Nice work.

Re: Robot in 3 Days : Completed Robot Video
 

Awesome job! It was fun to follow this. I think this proved that teams that can shoot SHOULD have a decent accuracy in early season.

Re: Robot in 3 Days : Completed Robot Video
 

Just wanted to say amazing work on the robot, this whole project has helped our team IMMENSELY in the past few days. Thank you so much for your dedication.

Re: Robot in 3 Days : Completed Robot Video
 

I feel privileged to have witnessed this. I consider this experiment a successful part of FIRST history, and a revolutionary idea on how professionals can inspire students across the globe.

What if in the future multiple groups of mentors from "Team 0000" started doing this, each picking a different aspect of that year's game to focus on?

Re: Robot in 3 Days : Completed Robot Video
 

Fantastic job on the robot. It wasn't just a robot in 3 days but a very capable one. When I saw it was a Frisbee you had to shoot, I thought this will be a challenge but you guys made it seem so easy.

This showed me why in our first two years of 1902 Exploding Bacon we made it to finals it was a privilege in working with you guys.

BTW was there any sleeping in the 72 hours?

Re: Robot in 3 Days : Completed Robot Video
 

That was amazing hope you do well. Have you thought about receiving from the top slot at the same time to minimize your feeding time.

Re: Robot in 3 Days : Completed Robot Video
 

Awesome job, guys!

Re: Robot in 3 Days : Completed Robot Video
 

Agree about the significance of the effort. Candid commentary is also inspirational. Not all 72 hours are on record, but enough to be quite comprehensive. Now how do we get car chases, explosions, pies-in-faces, and "that's what she said" spliced in so teens will watch? :) gangnam style? call me maybe? sandstorm?

No, really, guys, stellar work. Thanks.

Re: Robot in 3 Days : Completed Robot Video
 

what height and angle was that shooter at?
and awesome job

Re: Robot in 3 Days : Completed Robot Video
 

How far away are you guys scoring from? (like from 2:30-3:15 in the video) Awesome, awesome job!

Re: Robot in 3 Days : Completed Robot Video
 

Nice work guys.

Could the team post the total "man hours" that went into this effort and the relative years of experience of those contributors?
For those of you not sure what I am getting at, working 5 hours/day for two weeks straight will still not hit 72 hours.

My guess on it is on the order of 300-600 mentor level (persons with 4+ years of experience) hours.

Re: Robot in 3 Days : Completed Robot Video
 

I know myself as well as several member of my team have been watching your progress over the past few days. It's projects (and people) like this that make FIRST truly amazing. Great work guys, now go sleep!

Re: Robot in 3 Days : Completed Robot Video
 

Agreed. This robot would likely be a top 8 seed at most regionals, given decent drivers (and with 5.5 weeks to practice, they'd be ACES).

Now, the question is: How many robots will we see at competition that are nearly RI3D clones or borrow large design components like that shooter?

Re: Robot in 3 Days : Completed Robot Video
 

I know the guys pretty well, so I'll do my best to answer until they can respond...
It looked like they had lots of help from the live feed, but this is the core team and their rookie years. They were all students on FRC teams:

Dan - 2001
Andrew - 2000
Robby - 2003
miketwalker - 2002

They said in the chat, I believe, that they worked until about midnight each night and started at 9 a.m. on Sunday and Monday. So, that's about 42 hours and over 30 years of FRC experience.

Re: Robot in 3 Days : Completed Robot Video
 

I'm finding the humor that about this time every year someone has posted a "We have finished our robot" photo on chiefdelphi by now... and its usually a previous year's robot, some pile of parts, or something covered by a sheet, a black censor box, or a burred image.

This year those have been silenced.
One more way Robot in 3 Days has helped the community!

Re: Robot in 3 Days : Completed Robot Video
 

How much does the completed robot weigh?
Do you have weights of individual components? (ie: shooter, indexer, etc)

Re: Robot in 3 Days : Completed Robot Video
 

I think a lot, though I don't know how many will be intentional. A low hang, high shooter, human loading robot is a solid strategy that many teams I'm sure are considering on their own though the specifics of how will vary. I know I'd rather see 5 or 10 clones of this design than robots that can't score because their indexer jams and the lifter isn't strong enough.

Awesome job guys, this is an impressive bot even if it took a normal build season.

Re: Robot in 3 Days : Completed Robot Video
 

Thanks for all the kind words. The man hours were significant and we do have a few years of experience under our belt. It also helps to have most commonly available products already sitting on your shelves. ( Thanks Sponsors! ) One potential take away is that most teams pull late nights at the end of the build season. Why not flip the paradigm on it's head and have those late nights upfront.

George is spot on with our years in FIRST.

One thing I'd like to add is that we severely underestimated the time it would take to shoot and edit video. Mike and Andrew spent much of the first two days working on releasing videos and the live stream. It was painful to lose the extra hands but we had additional help show up at the right times.

On the weight: I think we are in the 85-95 lbs range. We took a weight prior to mounting the lifting mechanism and we were around 72 lbs. We have a few advantages like a lighter control system but we also didn't do anything to lighten the robot. We don't have weights on the individual systems/components. I imagine they could be estimated from CAD though.

Re: Robot in 3 Days : Completed Robot Video
 

Whats the final retail cost of all the materials involved? (Just budgeting for my pre-rookie team).

Re: Robot in 3 Days : Completed Robot Video
 

George good to see you here. Those were great years when we were all together on1902. I miss being with the teams.

I think IR3 are that good with the 30 years of FRC made it possible to do a robot in 3 days.

Are you going to be at UCF regional, let me know when you are in the area.

Re: Robot in 3 Days : Completed Robot Video
 

The sad truth of posting a nice quantity of good-quality video for projects like this is that you almost need to bring on a dedicated videographer.

I enjoyed following your rapid build process, thanks for posting ^.^

Re: Robot in 3 Days : Completed Robot Video
 

FANGIRL FANGIRL FANGIRL.
Wonderful robot!! Who's adorable daughter was that?

Re: Robot in 3 Days : Completed Robot Video
 

yes! this is spot on. These guys have set the standard. If your teaser robot pic doesn't show this much progress... don't bother.

Awesome project.

Re: Robot in 3 Days : Completed Robot Video
 

Our team was following the "robotin3days" videos from the start, and we are actually designing a shooter very similar to the one you guys built. Thanks for the help!:]

Re: Robot in 3 Days : Completed Robot Video
 

I'm interested in that indexer, how easy is it to get the discs from the slots into the robot, and to position the robot so it can get the discs into it?

Re: Robot in 3 Days : Completed Robot Video
 

Dan's, as shown in his WAI picture.

Re: Robot in 3 Days : Completed Robot Video
 

After watching the Oscar nominations the other evening, I was disappointed to not see Robot In 3 Days on the list for video and directing. Oh that's right, it wouldn't be eligible until 2013!
Seriously, the video and editing by Mike and Andrew was outstanding and really enhanced the Robot in 3 days operation. Also, it provides great documentation and materials for mentors and educators for future reference. I would like to know more about Robbie's flying car project which kept being mentioned. Is this just a funny topic or one of those projects Robbie is really working on? After watching him in action on the robot project, I don't doubt he could do it. And of course, Dan, as always, is a great emcee, informative yet entertaining.
Cute baby almost stole the show!
:) Great job, all of you!

Re: Robot in 3 Days : Completed Robot Video
 

Yes, Robby really does work for a company that builds flying cars. We are trying to get the team out for a field trip

Re: Robot in 3 Days : Completed Robot Video
 

Wendy,
What a great idea for a field trip. Go Wendy, Go!!! :)

Re: Robot in 3 Days : Completed Robot Video
 

I'm proud to call cute baby my own :-) We are thinking of doing a video just featuring her. Not sure what yet.

Yes, Robby builds flying cars. We are going to try to do some filming at his day job at some point. It's a pretty cool job.

Re: Robot in 3 Days : Completed Robot Video
 

Well, Robot in 3 days is an instant cult classic. We will be seeing it for years! :) I think a video featuring cute baby is a great idea and may I suggest a title? How to build a Wobot (or Bobot as she seems to call it both)
Can't wait to see it! And of course would love to see this flying car project that Robbie is working on. Good luck! We all will be watching!

Re: Robot in 3 Days : Completed Robot Video
 

This sounds like a lot of fun! Cute baby won't stop talking about the robot. Maybe we can convince Robby to give a video tour of the Maverick, flying car.

On another note, we've created a new video addressing many of the questions that we've received. We're also giving away free stuff! Ri3d swag and left over parts from our sponsors! Check it out here.

Re: Robot in 3 Days : Completed Robot Video
 

1) Are you controlling the speed on your shooter CIMs, or just hitting them with whatever voltage the battery has at the moment?

2) Did you do any tests to see what effect changes in battery voltage¹ have on the frisbee flight path?


¹due to level of charge of the battery and varying levels of current being supplied to other devices on the robot

Re: Robot in 3 Days : Completed Robot Video
 

Hello CD, so if you saw on our Twitter ( @FRCBacon1902 ) Robot in 3 days is now sitting in our build space to poke at and use as a practice defender bot. if anyone has any more technical questions or want more specific pictures of mechanisms let us know and we can post them. if any team in Orlando wants a closer look let us know and we can figure out how to get it over to you.

did some prelim measurements and weighing, the perimeter without any kind of bumper mounts is about 103.75 inches; the weight without a battery or freebees is posted below.

Re: Robot in 3 Days : Completed Robot Video
 

Ether, sorry for the slow response.

The speed is controlled in terms of percentage. The Canipede allows you to apply a scalar on push button control. In this case we ranged between .75-.9 which I believe is just sending ~75-90% of the batteries voltage, ramping as quickly as possible.

The battery voltage was not recorded at the time. We occasionally tested the batteries with a battery beak and rarely operated with a full charge. As the battery died there was an audible change in the wheels speed but we had no way to measure the difference at that time. We didn't, however, notice an extreme change in performance through our testing but our targeting was hardly optimized.

As a purely subjective observation, the biggest change with a dead battery was spin up time. The wheels seemed to take longer to achieve ~ max rpm and could require some extra time between shots fired. This seems to jive with the response of a dead battery as starting and acceleration current draw should be the highest, while maintenance of speed should be relatively low.

Re: Robot in 3 Days : Completed Robot Video
 

That is awesome!! I don't mean to tell seasoned FRC people how to solve a problem, but I think you cannot stick your fingers and hand through the feeding slot--so you might consider widening a part of yout easir robot's feeder slot to make it easier to feed frisbees into the robot. Outstanding work all around!! Now Rest!!!!

Re: Robot in 3 Days : Completed Robot Video
 

Interesting how similar 4343's robot ended up being to Ri3D, without even trying to.

85lbs without bumper/battery, human loaded non-stacked hopper gravity fed into a CIM powered shooter with AM Pneumatic wheels (though 4343's is just one wheel), strapped to a simple 4 CIM single speed drivetrain (Ri3D 4wd, 4343=6wd drop center) with a 10 pt hang (4343's was pneumatic powered)

Seeded #3 at GTREast, finished with a record of 15-3-0, only losing 1 qualification match to 1114 by 6 pts.
