Wait, so there isn't heavy metal in the reveal video?!? The robot is insane as well! Good luck with that tether!

But yes I do agree. It's an amazing design and I'm actually kind of jealous.

This link got posted to reddit, it got a little nasty in there. That may be why he's giving a warning.

The song, if anyone was wondering, is Earthquake by Labrinth feat. Tinie Tempah.

Someone want to make an 'awesome reveal video song' Spotify playlist?

Absolutely amazing. Every personal thought I had for many bots....& all in one tethered beauty.

I am not in any way being critical (please understand this).....I actually wanted to build (fabricate onsite at a regional by many teams), a pr. of shared clamp on 3 RC retrievers just like your flop bot pc. only (about 5 lbs. each), to attach to any robot that can simply only drive forward into the auto zone. End result the same (only many teams contributing COTS parts, building them together on Thursday morning, on a single design at the event only to stay within the rules, having each participating bot weighed w/ the fabricated part, then adding by movable clamps the shared community part as needed, where needed). Looks like the only way to even the score now is to follow through and work that plan.

A real tricky question though....As I understand it based on the ruleset, your entire 3 robots ~all 3 alliance team's bots (& all 3 pcs in 148's robot case, that are all tethered together, plus the other 2 full bots), must be in the Auto Zone at the end of the auto period in order to qualify for the actual robot set points. How can you accomplish this?....Or can you already, & you just did not show it in the video? (Remember, that auto zone is a volume, I see the part parked and tethered at the HP Tote Chute (yes, tote chute...LOL), station as being out of that zone). Am I parsing the rule too much? Or have you already asked a Q&A I have yet to see? Wouldn't your entire ROBOT have to be contained in the auto zone to receive those robot set points?

Or, are you just going to forgo the minor robot set points, in exchange for a great Stacked Tote set and the RC set? Among the other absolutely amazing Team 148 robot capabillities?

(Scared now that I asked that set of questions with nearly 48 Hours left...They still have time to work on that before bagging that beautiful 3 pc. beast).

I can certainly see Team 1678's 4 shelf RC snatcher, and Team 148's Batman, Robin & The Gotham Bridge RC Flop Bot, and just 1 more really fast Tote collector & stacker (I also heard news this weekend, and saw something about an amazing Israeli robot without a drivetrain that stacks & delivers tote stacks very fast from working nothing but the Landfill zone, among other super fast stackers), and have imagined them taking home pretty blue World Champs Banners already.

Great job Team 148! I knew we would see some really great "Out Of The Box" and into the tethered bot arena ideas this year. To get all that under 120 Lbs and in the transport config. is amazing! Be proud, show it LOUD! (If those tethers get chopped are you "leaving parts on the field?"
________________________
Now you are forcing me to actually re-submit (and work a lot harder to get the idea accepted somehow and actually done), to others my original idea of community built clamp on RC winch additions fabricated at a regional (since we will both be at the LV Regional and will compete with, and against 148 often)....At least for that RC snatcher next to the golden totes takes care of 2 things at once ~ Cans out of the way and in the zone, and Yellow Totes clear to stack & deliver. It would be the only way many others could possibly compete against your amazing 2015 bot in Auto!

Staying out of the way is easy if (You Are Lucky Enough To Be), on an alliance with them...You work only the landfill to scoring platform areas. You will win with them very often if you do...As long as you stay away from their tethers...no E-Stop is necessary whatsoever.

We will certainly look forward to competing with you...And no doubt fear competing against you....But, will work toward attempting to improve to defeat the amazing early results of 148's hard work and super brilliant design and congratulate your teams' reaching for perfection in 2015 in Recycle rush!

Now, please tell the secret to getting others to accept such an outlandishly & absolutely positively fantastic great Design Idea Set...Please Pray Tell? WOW.

It is shaping up to be a great FRC year! Thank you GDC.

That doubled over insertion of the litter into an RC right above the HP wall is also a thing of absolute beauty! Great simple solution to a tough litter chute feeding problem if it is actually allowed. (I see arguments w/ that one coming though perchance). Though personally, I cannot forsee any real safety issues with it whatsoever myself, but I don't make or interpret the rules....Was it Q&A approved yet? (It is being field introduced over the alliance wall without help beyond the HP who is fully outside the field at all times...who really cares how.

If you do not use up every game pc. (and prove my earlier "by Week 3 prediction" of someone using at least once all their game pcs up), in at least 1"Q or Playoff round" during the Week 1 Dallas Regional, I will be amazed & slightly disappointed. I see you, possibly 987, and a very fast stacker doing so, almost without a doubt.

Can you alone get all 30 grey totes inside and stacked by your lonesome in teleop? 5X6 Capped & Littered stacks delivered alone is a VERY, VERY high bar? Though a great bot at the other HP station could possibly relieve 2 stacks from you easy & maybe 1 more from the landfill. And, a great Landfill stacker might be able to get 3~4 from there (if they can handle those upside down totes too. Way too much of a positive thinker I am though.

I must go sleep, but the Dynamic Bat Trio is certainly on the brain. Again, Congrats Robowranglers!

That said that is an amazing bot... bots?

I actually think even if their tether died to Robin (Guessing that is the HP Tote Receiving portion)...That many bots already seen, could still attempt to pick up lots of short 2 tote stacks from it at least if the default gate position was gate down, if the power is accidentally cut to it. So still probably not a loss of the human station...and a great HP too!

Rules say that a tethered bot in multiple pcs. is still 1 Robot this year folks. (As long as it enters & leaves the field in the Transport config. and disassembly (setup), & assembly (departure), actions can each be accomplished in about 1 minute each. (Making that work is the trick they accomplished VERY WELL). "Rube Goldberg would be very proud." What an RG Machine.

Actually, considering the nature of the game, it's totally possible to use up every single game piece in this game. In fact, it might be worth it not to throw litter on Einstein to avoid giving up points.
That's actually crazy. There are a limited number of points. Can there be a tie!?

[The_ShamWOW88]

Good Game guys....good game....

no but seriously....amazing work....thing of absolute beauty....

[MrForbes]

Great job!

I don't see any issue with the tether and alliance partners, as long as the alliance partners can keep to the other side of the field. And it appears that the tether is quite robust, and it would take some effort to pull it into a robot.

Thanks for sharing!

You mean what happens at about 0:30? There seems that there would be a strategic advantage to doing it. They are one of those teams that would not do something unless it gives a strategic advantage.

There is also something interesting going on with the LITTER at about 0:22 in the lower left pane. A Human Player with amazing aim?

It looks like the Feeder Station piece builds neat stacks of two, probably to save time so that the main robot doesn't have to wait for the Human Player.

I suspect that they will be more worried about running over their own tether since the ideal match up for them would be a robot that takes care of the Landfill area and the Step and a third robot that uses the other feeder station. I am sure they have thought this through very thoroughly before committing and cutting metal.

Coworkers don't understand why I'm crying looking at my computer screen... just wow.

College is weird because there isn't anyone to nerd out about this stuff with.

Seriously, this is a really cool design, I could never have imagined such a system to work within the 120 pound limit, but this is incredible. Mind shedding a little light on how y'all shaved off so much weight from each mechanism?

[Steven Smith]

College is weird because there isn't anyone to nerd out about this stuff with.

Look harder There are a number of college level competitions that draw very similar crowds to what you'll find in FIRST, as well as just a lot of other "Maker" students that enjoy building. I didn't have FIRST in my area when I was in high school, and didn't feel like I was about to "nerd out" with others until college.

OP: Amazing looking robot. With the large transport configuration this year, teams have been given more real estate to push the boundaries of strength/weight. I know we build many things 5-10x stronger than it needs to be, and are less limited by weight than overall complexity and time. To see a team get so much robot (physically) into the 120lb limit shows a heck of a lot of optimization went into it... carving away every ounce of un-needed weight, and a lot of thought on the minimum parts needed to accomplish your design. I'd love to see a recap of that design process after championships if you'd be willing to share specifics.

Wow. I need to get my team off 8/20 aluminium so we can build lighter weight robots.

Seems like in Autonomous, they are conceding no robot set, and are pretty close to a RC set by themselves.

My concern is that the "hooks" on the RC are being supported by the RC at the beginning of the game. That is a no-no.
https://frc-qa.usfirst.org/Question/...-to-question-9

They might want to consider:
Alliance partners take out RC1 and RC2, and their corner bot dropping a hook into RC3.

Do a frame-by-frame starting at 0:52. There's a white piece of something falling down in front of the girl on the left. I'm guessing something's connected with fishing line, and they go fishing for the RC's at the start of teleop. You can kinda also see a shimmer of something dropping down on the far-right RC as Robin lowers its arms.

Technically the hooks can be in the RC holes, even touching the RC, so long as they're just dangling there. It's marvel to see.
