Hi, I am Madeline from HiJinx and I'm super happy that this is what is being done with the blade I adapted to work for 1lb bots.

[@TeamPanicRobotics]

Hi! I'm glad you like it, thanks for taking the time to adapt the blade. This entire crazy design would not exist without it

[@madelinemakes123]

​@@TeamPanicRobotics oh I would love to see a detailed list of your components. We have a fledgling 150g league starting in my area

[@TeamPanicRobotics]

I've been meaning to do a deep dive electronics video for ants, the problem is finding time to make it Hopefully I'll get it out before mid year

[@MakersMuse]

This is the most ridiculous antweight I've ever seen haha. If I was vs you I'd be tempted to just let it get up to full speed and unleash the chaos! 😂

[@TeamPanicRobotics]

I'm super keen to get it to full speed and just send it, but I think any opponent who lets me do that is in for a baad time 🤣

[@sliders15]

This may be the first time I'm glad rather than sad that you're on the other side of the world from the UK. That thing is terrifying and I do not want to have to fight it!

[@TeamPanicRobotics]

Haha thats very fair, tbh I dont know that this bot would meet the cube rule in the UK

[@GrumpleBots]

After watching the live stream I was so hyped to see this video!

[@TeamPanicRobotics]

Haha I might as well have! Good thing we fight ants in an arena designed for beetles!

[@CREEMkitty7]

Nice lawnmower I guess

[@razer259]

You do realise you've basically built an antweight Apex! 💥 (Oh god, RW10 flashbacks!) This has to be one of the most bonkers robots you've ever built! And I love it!

[@jb-br8bf]

I still remember JP’s “WHAT HAPPENED THEEEEEERRRRRREEEE?!?!” when the bar flew straight through the safety screen.

[@Living_Murphys_Law]

Apex was my first thought when I saw this, too. Hopefully this one doesn't explode.

[@TeamPanicRobotics]

Honestly if this bot doesnt Apex itself I'm going to be shocked and overjoyed Its definitely a glass cannon, I'm just hoping for one good hit

[@jong036jong5]

Congratulations. I didn't think it was possible looking at the numbers.Hope you get at least one spectacular hit out of it.

[@TeamPanicRobotics]

Thanks! I wasnt sure if it was, and I was fully expecting to be overweight on the first build Haha thanks! I hope so too! I dont have high hopes of it surviving the first hit, but I do hope it will be a spectacle of a hit

[@sammmhanson]

really like your use of a pcb as a baseplate, it's inspirational

[@TeamPanicRobotics]

Hugh from Melbourne put me onto using PCBs as a substitute for carbon fibre and its been working well so far. This is definitely the most structural use I've tried though

[@teamsmokeyrobotics]

I've wanted to see a 75+ gram weapon implemented on a 150 gram robot or in fact build one myself, it's cool to see someone's taken on that challenge! As a fan of ridiculously large spinners I do hope it does well or at least puts on a good show. Can't wait to see it fight!

[@TeamPanicRobotics]

Same here! I've always been curious as to how much of the bot can be weapon, we're at a bit over 50% now! I cant wait to fight it, even though I'm fully expecting just a one hit wonder before it explodes or OOTA's itself

[@teamsmokeyrobotics]

@@TeamPanicRobotics Haha I'm excited to see it. I'm trying to take on a similar challenge in the 1 pound division with a 1 wheeled bristle bot horizontal spinner which I plan to put a 300+ gram unbalanced weapon onto. It may just end up being absolutely destroyed in the end but I can't wait to build it and fight it!

[@KingSteve1253]

That video was awesome! Now you just have to build the rest of mini HiJinx lol.

[@Lumakid100]

If this is the newest version of A Little Obvious, I’m interested to see how it fights.

[@TeamPanicRobotics]

kind of, but A Little Obvious was always deigned to tilt forwards more and run a smaller weapon I've been tempted to make "A little 2 obvious" with a thick drum-like weapon, similar to what malice runs. Maybe later in the year...

[@robotwarsluvr]

@@TeamPanicRobotics Let’s go. Excited to see it

[@PrimevalParadise]

Fun name idea for this bot could be "Nothing But Bar"

[@squeak83uk2]

For the pcb esc could you do a space for a daughterboard mount? Ie pads that allow for a second board to be soldered to it flat.. ? Would allow smaller esc revsions and swaps without replacing fhe whole board.

[@sando5943]

I would love to see a little front skid or prong to help keep the nose/weapon up while driving. Looking forward to the fight report.

[@TeamPanicRobotics]

If i can print one thats less then half a gram I'll add it 🤣

[@ThatColdSketch]

You should name the the bot "Sombrero" because it looks like a sombrero when it spins up.

[@ruvimsemenyuk8224]

It’s pretty much triton but overhead spinner and a ant weight lol

[@TeamPanicRobotics]

with a (proportionally) heavier bar Its going to be nuts to fight

[@TeamBilly]

That's impressive! Even if you can sorta drive, I think surviving your own hit is going to be a really big problem

[@TeamPanicRobotics]

Oh for sure! thats part of why it has a hardox frame, to try and survive the big hits

[@TeamBilly]

​@@TeamPanicRobotics I assume you meant the weapon bar? I meant the motor and chassis as that weapon bar will transfer so much force back into those. I don't see the weapon bar itself ever having an issue

[@TeamPanicRobotics]

Oh sorry I was running down a list of recent comments and missed that this was not about the new melty brain. Yes I'm expecting this to have trouble with the energy expended when it hits, it will either break itself or go flying, but either way it will be fun to watch Also it can definitely drive, I had it spinning and driving in the test box footage

[@jb-br8bf]

When it span up to full speed it sounded like a rotary engined aircraft!

[@fasthippy]

When it comes to energy impact. E= Mass * velocity^2, It might be interesting to create the a weapon that goes as fast as possible. Perhaps a disc with a tooth that is held back by a spring and only overcomes the spring as some stupid speed. Kind to opposite exercise of what happened here- maximize speed over weight.

[@TeamPanicRobotics]

That would be interesting for sure The problem with super high RPM is that bite decreases with an increase in RPM, so you have all of this energy stored but struggle to effectively deliver it into your opponent

[@teamsmokeyrobotics]

Dude! When's this thing fighting!!:) I understand the event cancellation and I'm wondering if there's any update on that? I am very hyped to see this thing fight.

[@TeamPanicRobotics]

All going well, it will fight next weekend And there will be a fight report the week after

[@teamsmokeyrobotics]

@@TeamPanicRobotics Let's goo! I love big spinner bots and I hope this robot can land some large hits

[@markxr1]

That is as brilliant as it is crazy. It's a shame you couldn't get your ESC circuitry working on the board though. I look forwarding to seeing it fight

[@TeamPanicRobotics]

Haha thanks! It is a shame, but thats what I get for using a dirt cheap micro, the interrupts worked fine on their own, but as soon as I run the pair they freak out and one just stops working all together, very annoying. If I do a v2 it will have a chip change

[@rdpeake]

@@TeamPanicRobotics do the interrupts share the same clear flag or something like that?

[@TeamPanicRobotics]

I dont think so, but I'm really not sure The spec was all in Chinese and I translated it, but things dont always come out clearly when you do that I tried both the main 2 interrupt pins and then the specified software interrupts and could never get more then 1 working reliably at a time

[@cadenschipani5586]

Hey Ben! I'm looking into designing antweights and I like that tiny red brushed ESC you used. Any info on where to get it/what it's called?

[@TeamPanicRobotics]

Its from the UK, Bristol Bot builders sell it. There's also a reseller in Aus: BotBitz I do not know if they are available in the US

[@cadenschipani5586]

@@TeamPanicRobotics Thanks man, I'm from the US but I'll see if it ships 😁

[@mechmindStudio-o8q]

Hi i justed wnated to know that in electronics what have you used instead of Arduino and motor driver and module because they are to small in size

[@TeamPanicRobotics]

This video: kzbin.info/www/bejne/qYbXlq2tltqlgrM Goes over most of the electronics I used in this build. The only difference is that I used a smaller battery, and smaller motors

[@MrCarrellScience]

Lowjinx is funny. I also like "Big Hits" as a name. A little on the nose, though, haha. This is going to be really fun.

[@TeamPanicRobotics]

That is a bit on the nose, but its also accurate I think it will stay LowJinx or LoJinx though, as it was a name given to me on the CAD stream and I really like it, especially as HiJinx is an undercutter, it makes sense for an overhead spinner to be LowJinx

[@hogfanboy9443]

great video, I like the way you come up with out of the box designs. What motor driver and microcontroller were you planning on the PCB? Looks like the way you were going to connect the N20 motors to the PCB was similar to what I did ( created a small PCB that is a back plate on the N20 and it connects the motor connectors and right angle female headers to connect to male headers on the PCB) very clean, was that similar to what you had planned? I used ESP8266's to act as wireless and microcontroller on both the bot and controller, because I was focused on making an inexpensive complete bot and controller. Using the ESP8266 and ESPNOW, sending data was easy and didn't have the interrupt issue. This year I got cheaper by doing a 1S design that can easily do flea weight and has a TP4056 charger module soldered to the PCB to charge the bot. Thus I only needed to supply students with a USB cable for charging. Even though I have spots on the PCB to plug in a servo or brushed esc, I have not gotten there because we have no arena that can safely battle in. Does anybody have ideas about a cheap and safe arena where we can get a little more destructive?

[@bami2]

That is quite the silly build, pretty amazing you managed to have it within weight by half a gram. Could you mount the weapon to the motor axle before mounting the motor in the chassis? Does the competition you want to take this to have rules on spin-down times?

[@TeamPanicRobotics]

Honestly even with all the weight saving I was expecting to be at least a gram over on first build, I was blown away to be under For the video I could have, but it would probobly have been harder for comps, as I was planning to loctite the weapon motor down, so removing it and putting it back oftern wasnt a great idea and I wanted to avoid it. If it couldnt get the weapon on while the motor was in, I would have done it that way I think so? They use a fairly standard ruleset with a couple of minor mods to define the plastic B class. But I'd need to read it again to find out for sure, either way I should be able to meet it

[@wflagg]

prediction - Anyone who doesnt box rush you will have a bad day. Anyone who DOES box rush you, might have an easy fight.

[@TeamPanicRobotics]

Hahaha I think thats accurate, the slow spin up does leave me wide open for a box rush

[@WackyNinja]

Do you reckon the bar would spin up faster if you counter-spun the drive-half of the robot?

[@TeamPanicRobotics]

oooh, maybe! I'll have to try that out in the test box before fighting it

[@alexpick518]

One of the robots on my college team was a ringspinner. After a decent amount of damage, they had a weapon motor down at the start of a fight. The only way to start the weapon was by spinning the robot.
