thanks, glad people enjoy following along! I initially considered a shuffler but they are generally more fragile, complex and slow than wheeled bots. there are exceptions to the rule like coldsnap which is another shuffler undercutter that seems to have cracked the code to smooth and fast shuffling but it takes alot of effort to get there. I've got ideas for a shuffling ringspinner which you'd be familiar with from james' videos although mine will have a different approach but for yellow specifically its kind of my KISS robot (keep it simple, stupid) also australians have 'spirit of the rule' meaning that the weight bonus is there to encourage unique and complex designs and that the shuffle mechanism should consume the weight bonus. tldr: aussies generally dislike shufflers that are only shufflers to have bigger weapons

@@mattstewart2750 kind of, I cleaned both surfaces and sand away the coating on the rotor, apply JB weld to the weapon and slip it on. I use a jig made of Lego to hold everything level

@engineered_cha0s Ahh, that makes sense. Thanks for the reply.

Oops 😅 I was copy pasting the text blocks... Must've missed that one

@@AlexApacible quite possibly! I've been getting around, been to Wollongong, Adelaide, Hawkesbury and have appeared in some of Broken link Robotics' videos Oh and I did a few fights at comic-con

Cheers, I'll have to look into that

Could it possibly be related to the colour space of my phone not being corrected by the editor? It took me a few videos to get that right

@@engineered_cha0s The video looks fine. just the audio where you're talking. The mic is picking up low frequency background road noise or something. It might not be very obvious unless you have some good headphones or a subwoofer, but the bass in the audio is unnecessary when just talking because a human man usually only talks as low as 90hz or so. so anything below 90hz audio range should be removed.

Ah right ok, that'd be because I was recording in my backyard there's cars and birds in the background 😅 the most recent video's audio was on a proper mic inside so should be better

Haha I wasn't familiar but yes I did think it bore resemblances to a talon

Thanks! I really like it too. The only thing it really compromises on are thagomizer style hits but that's a fair trade

@@engineered_cha0s - Hmm, that's a good point... I do like that Cheesecake can turn into opponents for a cheeky side hit. Looking forward to seeing Y&D's tournament fights!

It's the "ant controller board" based off of the malenki but much cheaper from llamaforge which is an Australian parts supplier

@engineered_cha0s nice! I'll have to look at it

Is your weapon press fit onto the motor

Y&D has the rotor of the motor sanded and then jb-welded to the blade. I rest the blade on Lego bricks to make sure it's level

@@engineered_cha0s Nice, the more the merrier but.... isn't it listed at 25 dollars? It's not cheaper then, it's slightly more expensive.

Haha thanks Originally tried to do a 'stuff made here' type explainer thing but drifted from that as I went

Tell me about it... Three events in and I've finally done an entire event without losing a belt... Toothed sounds good, transmits torque through the teeth rather than friction so would probably be a bit more forgiving for tension

I've used o-ring belts for drive for a while now in my 150g bots. The belt tension is absolutely critical and small variations will have a huge impact. For a 75mm circumference belt I found a 2mm change in length was noticeable. I still haven't got a formula or rule figured out for the optimal tension, but highly recommend making 10 different sizes and testing them all just to see if you can find a tension that works best because when it is dialled in they work amazingly well.

Yeah I think my "method" extends as far as loosely wrap the cord around where it has to go, pull it taught, go "a smidge" (scientific terms I know) further than that and that's a good place to start testing and shortening

@@paydaygh9388 yeah, I think I mentioned I did end up battle hardening them which helped. I'd just never done it before that because I'd asked other competitors and they'd basically never seen a magnet shatter at this weightclass and said it was unnecessary

Both sides are 2mm I'm not sure what grade

@@rykerdaly I use 2 3V 500rpm n20s for drive and an 1806 brushless motor for weapon

Good spotting! Its not sucking too much power exactly but yeah the torque reaction of the weapon spinning up spins the whole bot lol. Not necessarily an issue as the same can be seen in other bots (tombstone often does a full 360 when starting up) but definitely something to consider. Wider wheelbase would help with this too. Drive is definitely underpowered and generally hard to drive. All things will be improved in the next iteration.

~30g of Grade 5 titanium (:

@@Me0fCourse haha cheers, glad to hear it!

@@engineered_cha0s Looking forward to the next one. :)

@@Me0fCourse me too (: it's a development vid which takes a bit longer and I'm trying to figure out if I can animate some visuals to concepts I explain so might be a bit of extra time... Free for the next two weeks after that so should smash out some more then too

@@68HC060 sorry I don't follow 😅

@@engineered_cha0s - look for a face with eyes, nose, mouth, hair ... 😉 Edit: It's the milling-chuck mirrored "upside down"

@@68HC060 ohh right ok.. i got as far as the chuck being a "collet chuck" so i thought it was a play on words 'call it chuck'

@@engineered_cha0s - well, it's also a little play on words in addition. 😉 But the face looks so much like a person, I was distracted when I watched the video. 😉

@@5eurosenelsuelo nope, just practiced driving both ways (: my new iteration uses an all-in-one board from llamaforge that serves as a reciever and drive escs which lets me assign a switch to flick to invert controls. Being able to drive upside down is still a useful skill though

Most people just learn to drive inverted. It's really easy after a little practice.

@@alexsalchemy it really was! (Once I got past the motor stresses) Also I find it nuts and so cool that the guy behind the inspiration for my bot watches my videos (: say goodbye to this version though... New one is quite different!

@@engineered_cha0s - New version? Awesome! I might end up taking notes! The smaller the robot, the quicker it can evolve, I'm excited!

@@ukmayhemproductions hi! I'm competing in Wollongong, Australia but in general a good place to check is robotcombatevents.com although they're mostly American events. If you're EU/UK based then Bristol Bot Builders have an UK & EU Events Listing section on their website. Otherwise have a look around for Facebook groups! Good luck (:

@@YH-du3jc yes that'd give me another 75g for a total of 225 although it's a trade I'd rather not make... The tpu stands up wonderfully against everyone I've faced so far with the largest gash by far (apart from tests) being sh-bang during this rumble. Top armour might be worth investing in but I can just take my side armour off for that. Shufflers come with downsides (more fragile, slower) and at the moment I don't think it's a trade worth making. I'm developing a ringspinner which will probably need the shuffler weight bonus though...

@@YH-du3jc at this point I think the best improvement I can make is actually investing in better drive. This will not only let me capitalise on hits where my opponent is disoriented but also increase my energy transfer from the weapon as "bite" is how much of the weapon engages with the opponent which increases with speed of impact. Meaning improving drive will actually make my weapon more effective too!

Considered that for this design but didn't want the complexity of another option confusing me during fights (also the point was biggest stick and think about the rest later)

Thanks! The results would agree (: it's since been redesigned so should be even better!

I was gonna go with "banana cheesecake"

@@L1m3r no it’s yellow&dangerous

Thanks! The logo is a part I made from a previous project. I was trying to design a 3d printable bistable auxetic material (Steve mould had a good video on it). Anyway, couldn't think of a logo so made it black in fusion and took a screenshot 😅 Thumbnails are screenshots with extra stuff added in with ms paint (not the highest tech ever).

Thanks! I saw your video and then binged every other one 😅 took design inspiration as you can see. Its now actually kind of evolved and taken a new path with mk2

I did consider that but kind of wanted to stick with the simplicity of the "big stick" mentality especially for a first robot. It let me put all my weight into weapon and gives me a simple gameplan for each fight rather than being overloaded with options. I've definitely since considered (and hastily tried) a rear wedge but I think I'll need more modularity in general as it would be good to maybe have a lighter weapon with options for overhead armour or a wedge

@@gtdgabriste1 haha I get what you mean 😅 just gotta keep doing things and we'll improve. I hope to get to James' level at some point! Definitely something to strive for.

@@RobinRoosenbrand yeah, they're always fun! They're open to anyone and everyone so not just the losers (as long as you're prepared to come out of it in multiple pieces)

​@@cinobro6393 it's a Tormach 770M non-servo owned by James (Broken Link Robotics) tbh I don't really know much about mills

@@engineered_cha0s That’s awesome, they’ve really rare down in Aus.

@@cinobro6393 yeah, makes sense. He had to ship it from the US (said he could either get a car or this)

@@BrokenLinkRobotics Thanks! Yeah, they really were 😅 I might join some of the events into one video to try and catch-up on the backlog.
