Upgrading My Combat Robot - Y&D Mk2

[@alexsalchemy]

Wow! A 4-wheel-drive horizontal? This is the coolest! I love how far this robot has come already.

[@engineered_cha0s]

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

[@alexsalchemy]

@@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!

[@engineered_cha0s]

Sorry for the long break between uploads. I was taken by the plague a few times. I'm back although also dealing with school so hopefully I should resume catching the channel up to date. I also tried some new things with editing which i think came out alright although my laptop didn't enjoy the process.

[@Eduardo_Espinoza]

I love that it looks like the CSGO claw :)

[@engineered_cha0s]

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

[@birdckaje_OCE]

Awesome video as always. Keep it up!

[@bobdehuisbaas1]

Truly horrific, absolutely amazing

[@AlexApacible]

I swear I saw this at a tournament

[@engineered_cha0s]

@@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

[@Me0fCourse]

Excited for the next one. :) ´

O-rings as belts is so annoying. I used them as weapon pulley in my fairy, and they slipped so bad. Now I use 3M toothed pulleys made of TPU, with the belt being a 6mm wide belt I cut in half lengthwise to make a 3mm belt. I have no idea how to make it accessible for drive. Maybe print an S3M belt out of TPU, but only 2mm wide?

[@engineered_cha0s]

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

[@TrentSheather]

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.

[@engineered_cha0s]

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

[@Handle1795]

I've started watching your Vids cos I watch James's Videos. I like seeing the development of your robot. I do have a Question tho if this is the weapon choice that your set on, have you considered a shuffle bot? Look up Mudskipper or monkfish I'll think you would find it interesting

[@engineered_cha0s]

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

[@andrecook4268]

Noice.

[@BrokenLinkRobotics]

Good stuff, swanky animations too

[@engineered_cha0s]

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

[@hugh_phan]

goated

[@Josstrigaming]

Nice! Whats the name of the board you changed to? I cant seem to find it

[@engineered_cha0s]

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

[@Josstrigaming]

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

[@Lusidous]

Is your weapon press fit onto the motor

[@engineered_cha0s]

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

[@olisk-jy9rz]

@@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.
