I built an antweight combat robot in a week, but then...

[@connor1586]

That arena having no roof is very worrying if they are allowing spinners. Even if they are at the 1lb weight class

[@DrumBotics]

Yeah right, I said that myself there, but I won't go home after a 300 kilometer drive😀 It was a very little competition and they probably didn't even think that there will be some powerfull spinners.

[@connor1586]

@DrumBotics In which case I hope they saw what your robots are capable of and make a roof! Or just send them the IIT Techfest 2014 video of a guy getting brained by shrapnel and hopefully they'll realise why you need a roof.

[@Plant-c9p]

Can’t wait to see more of this bigger Tytotu! A titanium drum might be a big difficult due to weight, though. Would love to see an antweight kit like this! ❤

[@DrumBotics]

@@Plant-c9p Machining a drum like from my 200 gram tytotu would be no problem, but now I'm trying to make it good with a printed one with steel teeth.

[@QWERTY_56_WASD]

1:45 my horizontal spinner also made in 1 week hahaha. Great video

[@AQucsaiJr]

I love drums… Would be very interested in seeing how a 1lbs tytotu would perform over here in the US.

[@Adomanerr]

Wow amazing video, I immediately subscribed!

[@thirtythreeeyes8624]

I think the PP was printed a little cold it looks like the adhesion isn't great and PP should have some of the best layer adhesion of any material. It's also the lowest density though so remember the same part in nylon might be stronger but, it also will weigh like 20% more I think.

[@DrumBotics]

I agree, it was printed at 260 celsius and Now that I tried printing at 300 it looks the same as I thought the temperature would decrease the quality of the part.

[@thirtythreeeyes8624]

@@DrumBotics With good settings PP has TPU like layer adhesion and elongation at break is higher than any other non flexible material but, nylon has a lower coefficient of drag, higher tensile strength and stiffness, which might be better. I'd be interested how a higher temp PP part would perform.

[@DrumBotics]

@@thirtythreeeyes8624 Two weeks till my next competition so I will give it a try.

[@SpiderWaffle]

8:47 Why not have a direction swap function, the bot is very symmetrical either side.

[@DrumBotics]

I thought self righting with gyro would be enough.

[@SpiderWaffle]

@@DrumBotics Ya, but the time it takes is so detrimental. You're very vulnerable, plus can't capitalize and go offense when you're trying to self right like that. Would be so much better if you could just seamlessly go right back to fighting. I bet you'd have won the rematch with that difference.

[@DrumBotics]

@@SpiderWaffle I guess at first for example the 200 gram tytotu version self rights way faster, but as we saw the 1 pound version self rights for some reason slower and that shows.

[@SanderMakes]

Those gyroscopic "evades" vs. NYX were awesome! Doubt those were intentional, but they looked sick!

[@DrumBotics]

@@SanderMakes Yeah it looks pretty cool, I was trying to self right onto my good side

[@zeDoSauRus]

In Croatia we have only 3 pound (1.5kg) :)

[@TomcoDesigns]

imagine what you could have done in 2 weeks

[@DrumBotics]

@@TomcoDesigns Haha😀

[@FreyFox87]

I didn't even notice the pit until you ended up in there 😅

[@KingPieGamez]

Loved the video, also can you make a super wide 3 pounder, with two of hotlines weapons side by side?

[@DrumBotics]

Now I'm focused on antweights, but in the future I hope to make a beatleweight just not in this moment.

[@KingPieGamez]

@@DrumBotics well, either way I can't wait to see what you make next :3

[@raphamyc]

Hi, I love your videos. I'm from latin america and I also participate in this kind of 500g tournaments, could you give me some advice on what kind of filament to use in my combat robots, so far I used petg and it was not a very good idea xd.

[@DrumBotics]

Nylon pa6-12 is best so far, very tough, carbon fiber nylon of needed something stiff, and tpu for side armor of ot doesin't need ti be stiff.

[@finnseyffer3906]

Tyto-two 💪

[@OptimusRoboticsPoland]

So I guess I'm visiting Lithuania in March :)

[@DrumBotics]

@@OptimusRoboticsPoland Yesss😀 That would be incredible!

[@Greanbeens14]

Does the motor fit in the drum with only friction or is there glue/material involved too?

[@DrumBotics]

This time, because the drum is printed out of soft material it is pressfitted, but in the future I will use something like nylon which is harder yet still tougher and will put some glue there in as I press fit.

[@Greanbeens14]

@@DrumBotics so if it was made of metal, would it be pressfitted or glued or would you use a collet?

[@DrumBotics]

@Greanbeens14 When I need to fit a motor into a metal hub I make the hole a bit bigger and just print a soft adapter and then the motor press fits perfectly.

[@Greanbeens14]

@ thanks!

[@alteronteam]

What about the rules? I am planing an competition here in Brazil with the same categories and arena size

[@DrumBotics]

3minute rounds till one point double elimination if there's more competitors and if there's not that much robots then it's sometimes devided into groups so we could have more fights.

[@alteronteam]

@@DrumBotics thank you

[@Dub-785]

cool also I have a question are you gonna replace the drum with a different material or is it going to stay the same

[@DrumBotics]

Yes, I'm now working on this particular 1 pound drumspinner and it will be way better in the future. Planing to print the drum out of nylon or TPU 100 procent infill and in theory it should be indestructable, of course a lot of testing is still needed.

[@Dub-785]

​@@DrumBotics ok thanks

[@chyrt]

Your bot did really good, how can you counter the gyro effect? does NYX have a channel or page somewhere?

[@DrumBotics]

@@chyrt No, nyx is just very low to the ground and It's affected by the gyro much less than me.

[@chyrt]

@@DrumBotics Interesting, was the rotating mass of the spinner the same on both bots? does nyx have a instagram page or something?

[@DrumBotics]

@chyrt Yes it's balanced, but the weapon is non symetrical so one tooth is longer. He doesn't post anything about his robot on instagram.

[@prodgbm]

Not having a roof is super concerning. That could have easily led to a severe injury if a part failed and hit someone or even worse a robot could get launched OOTA. If you have contact with that event organizer please tell them to invest in a roof.

[@DrumBotics]

@@prodgbm I know right, I kept saying this to them, but as this competition was too small and probably won't grow I won't come there again. Without my team there were mostly pushers with no weapons and I get why they thought the roof is not needed.

[@amka1097]

Are you voing to participate in Preiļi, 25th january?

[@DrumBotics]

Of course! I will bring my 200 gram Tytotu eggbeater, so it will be really intresting. Also I'm planning to finish my new version of this 1 pound tytotu and bring to preilu 1 pound category.

[@jacobmoscarella9057]

How did you get your p1p to print nylon?

[@DrumBotics]

@@jacobmoscarella9057 Printing is the easy part, but making the nylon stick to the bed is a pain. finally after some time figured how to by buying myself a g10 garolite build plate that was quite expensive, but nylon sticks to it perfectly.

[@jacobmoscarella9057]

That makes sense

[@blinkdagger4393]

hello what bambu lab 3D printer are you using?

[@DrumBotics]

@@blinkdagger4393 Bambu p1p, with a custom enclosure for printing with special filament like nylon or polypropylene.

[@blinkdagger4393]

@@DrumBoticsi am planning to buy a 3d printer bambu lab p1s. as a beginner, i got a little bit of knowledge about 3d printers. will this printer work on printing nylon, polycarbonate and carbon fiber? the parts will be used on my combat robot.

[@DrumBotics]

@blinkdagger4393 Yes bambu in my opinion would be the best choice and of course p1s has an enclosure so even better. Just know when printing nylon you would most likely need an advanced g10 garolite bed. Cf-nylon amd polycarbonate prints perfectly fine.

[@steazoxgaming]

will it be france compétition ?

[@ineedachannelname8505]

Why not just make 2 tytotus with some beef?

[@ineedachannelname8505]

Why not multibot?

[@DrumBotics]

​@@ineedachannelname8505 Actually I have already competed with two tytotu's way back in Latvia ryga's competition and it went terrible, didn't even deserve a video🙂

[@SpiderWaffle]

May I ask, I'm curious, what are your origins? Because you sound extremely American/Californian.

[@DrumBotics]

@@SpiderWaffle I'm Lithuanian. And the truth is that I'm not the person speaking as my english speaking is not that good, so I just have another person who speaks english perfectly and who also has a very good microphone to speak everything that I have written. I haven't really published that yet to the viewers tho. Hope that is clear.

[@SpiderWaffle]

@@DrumBotics Okay, makes sense I thought something like that. Was too good to be AI voice.

[@DrumBotics]

@SpiderWaffle Oh yeah that AI voice was terrible when I used to use it earlier.
