It needs a heavyweight version
Maybe someday a long time from now
Thats what i first thought seeing it. Cool looking action
it'd probably be the coolest control bot in heavyweight history
Love the new design. Can't wait to see how it performs!
Thank you me too!
really hope this design works well enough for you that you can take it to norwalk eventually. love it when new designs enter the fray
You and me both! I think the armor probably needs a rethink for Norwalk but it is something I want to do someday.
Really love the design of this bot. Good luck at the Jersey event next weekend!
I am having far too much fun watching Shrapnel Mine zip from one side of the screen to the other.
This sort of design would make a cool replacement for Kraken
I think Matt Spurk has a good idea in mind for the next Kraken
@@JustCuzRobotics how come you didn’t change the angle of the forks
I would have had to pay for new ones to be cut and it seemed a bit of a waste of money since I have 3 pairs of good ones. Maybe next time.
I'd absolutely love to see you captain a heavyweight team based on this design at BattleBots. It's something of a reverse Skorpios
I need to prove to myself this thing actually works in combat before I would even consider that, and then maybe try scaling to 30lb. The use of a servo for the arm would be hard to scale up, I would need something totally custom at any weight class over 3lb.
@@JustCuzRobotics a 1:5th scale servo? 100 or so kilograms of force
Even if that might be strong enough I don't think its output would support the load of a 30lb robot slamming into it. The 3lb bot is using a 35kg rated servo which is plenty of power (chineseium so probably more like 20kg-cm). But I'm using the servo case as the structural element to support the arm. Plus the 1/5 servos seem to cost as much or more than a brushless motor and beefy gearbox together would that would have many times the power.
amazing montage at the beginning and very inspiring presentation throughout the video, this channel is a big inspiration for me and my university team trying to get our big break
Thanks so much! Happy to provide inspiration for any new builders.
Dude, you're vide editing and overall presentation skills have gotten so much better. Great stuff, man!
Thanks! I've been trying to put more time and energy into the intros lately. Glad someone noticed 😊
Working on a Ring spinner, always getting a boost in motivation when I see one of your videos up!
Glad to hear it!
This looks really cool, can't wait to see it in action!
Watch the older event recap :)
Damn I live right around the corner from that event. I would’ve taken off and got my beetle going. Good luck Seth! New Shrapnel Mine is looking good.
Hope you've got some vacation time to use up! Thank you
Oh wow. Shrapnel Mine will fight again to join along with Division. The two bots will be formidable in the next event.
Unfortunately for me the competition I'll be going to has currently only six other robots registered so there's a very good chance they have to fight each other... thankfully I can always forfeit that one! I think it'll be a lot of fun to show off Shrapnel Mine against a less competitive field than Norwalk
@@JustCuzRobotics Oh. Maybe next time from a different competition.
Work of art
That's a high compliment, thank you!
ok I eventually saw you didn't have them on but the sped-up footage of attaching the spike wheels immediately followed by it driving around on your hardwood floor was too funny!
My apartment has a fake wood vinyl floor. I tried the spike wheels on it briefly but it was absolutely ruining the floor and peeling up some of the veneer. It should do a lot better on an actual wood floor lol. Even without the spiky cleats I was able to push 19 lb of water-filled plastic jugs across the floor
How much faster do you think you could possibly make this thing before it's uncontrollable? Great stuff man hope to see the event go well !
I probably should limit the throttle because at full speed it should be able to go 35 mph 😅
even a featherweight version of this would be insanely scary and intimidating
@Seth Hey I was just scoping out you cool bot and was noticing you have a vertical blade. Why didn't you go with a horizontal blade instead to slide underneath the beater-bars? That way you'd never have to go weapon-on-weapon and take all the kenetic damage you could just eath their underside (allot of jokes there)?
Aluminum foil = best undercutter weapon
You can run the servo at 9V and the receiver at 5V - just tie grounds together and be careful with your 3 different B+ lines. My plastic ant uses 2S to power the servo directly, and the receiver is running off 5V from the ESC BEC.
That would require running two different BECs though. I have way too many things inside this bot already lol
@@JustCuzRobotics Many ESCs provide it for free though.
would be sad if you went against mixtape :P super cute and fast though!
I love a good bent wej
What rubber you use as tire?
Looks almost like a yoga mat with a pattern but its seamless? Whaaat
I think it's a polyurethane casting, look for "How to Make Custom Wheels for Your Robot - Molding/Casting Polyurethane" video on his channel.
Yes they are custom cast tires using Vytaflex Shore 30A urethane over a 3d printed TPU hub. I prototyped this system on SMine last year and it worked really well. Then I adapted it to Division where I was able to upgrade it substantially and prove that it can take hits from the best Bots around. These wheels get an absolutely ridiculous amount of grip. I was able to push around more than 19 lb of water filled jugs no problem with the bot only weighing a little over 2 lb
Polypropalen for better heat resistance?
Better impact resistance
I wonder how this design would translate in battlebots
Why does everyone keep asking me to do this LOL. It would be difficult to scale to that level, I may try a featherweight version if this works really well at 3lb. The beater bar meta at the 3lb level is extremely prevalent especially at Norwalk but at Battlebots it seems mostly about long forks and ground game and 4 wheel drive vertical disk spinners which would be a lot harder to counter with this style bot.
I've been proselytizing this a lot, but anytime I see someone using a manual screwdriver for bolts around the sizes used here, I can't help but recommend they get a nice precision electric screwdriver. The amount it saves you on wrist strain is so worth it.
I recommend the Miniware ES15. Its type c charging, open source (so you can change the firmware as you'd like, if you'd like), has high torque for a precision screwdriver (which makes it good for this type of 3d printing based project), and has many features that help with fast assembly.
It's not going to drive deck screws into 2 by 4s, but it'll more than suffice for your needs here torque wise.
Honestly, I know 100 bucks sounds like a lot for a screwdriver, but your wrists will thank you if you pick one up. With this thing, I very rarely use l keys or manual screw drivers anymore (especially since it can also be used as a manual screwdriver anyways).
I already own an ES15. Awesome for M2 screws. However some of these screws I need to tighten to a specific degree by feel and many of them actually require a lot more torque than the es15 can put out. I use a No Cry cordless driver a lot. Just happened not to use it on camera this time.
This thing looks scary,good luck at Lbd,can’t wait to see ya there,hopefully not in the arena,I’m currently now panicking and trying to find a counter to this thing cause this config is practically made to counter me,but good luck,also I ask if you start to get me,don’t cut any expensive parts cause rectified ESCS are sold out and the stuffs expensive,and not the lipo,already dealt w 1 fire,don’t want another
I assure you the level of precision I have is not that great. If you don't wanna get hit just tap out!
@@JustCuzRobotics probably will and idk,I’ll still probably try and think of something,cause I just wanna protect my insides
Those spiky grips are a giggle, poor floor.
It's been done by a bunch of other robots like Lynx and Eruption to great success. Only the very tips of the spikes actually dig into the floor and they don't really do that much damage
Uh oh, polypropylene all the things!
Hey if it works it works!
@@JustCuzRobotics Worth a shot and is a juicy target because of the weight savings of that filament
