interesting you don't have any rc wheels there. i thought these would be the no.1 resource. There is even sticky sauce for them.

So how's the arm taser coming along

Hey I need my test box back!

Fantastic fight report, subbed. For the closer wins it would have been nice if you clarified you got the JD, wasn't so sure for a while.

So with my beetle undercutter I have the following: Weapon RPM: 12k (artificially limited to stop it from tearing itself apart) 467 joules Drive speed: 3.28m/s I'm consistently one of the hardest hitters at events but that comes at the cost of bending the crap out of the weapon shaft or shredding my own bottom plate every so often. As a fun fact this bot was originally meant for a local 5lb league that shut down during covid and never restarted, so I shrunk the chassis to make weight for beetles and kept the massive weapon.

Still can't believe I lost to Potato by getting high-centered on its horn.

The jumpscares 2:56 fork jumpscare 12:55 liftoff jumpscare

Hound seems like a great bot

Great bot and video!

Great video! I really liked the little cut-aways doing a bit more explanation on relevant things (like the note on the bottom). Would some stabilizing forks on the front help with the flipping around the weapon axle that seems to happen quite frequently? The fight vs Project Liftoff was such well driven, from both you and the driver for potato. Textbook example how you should fight a meltybrain. Sad thing that the fight vs mixtape basically ended because of a cockup in the pits, but I guess that's combat robotics.

Hound!!!!

That was amazing to take those hits!

Potato is indestructible

brilliant showing on saturday btw

Thanks for sharing! You can edit the beginning out in your youtube studio so you do not have to upload it again.

Maybe edit your videos a bit. There's over a minute of blank screen at the beginning of this one. Also, 24 joules of energy on Hound Mk1? Considering most antweights pack a lot more punch I suspect you missed a decimal point. 240 joules is pretty respectable for a Beetle, one of my ants has well over 300 joules, but it's a real glass cannon. Since you asked, Beetle Drum spinner, max speed 16700 RPM, Tip speed 101 M/Sec, 321 joules Ant Undercutter (the glass cannon) 328 Joules 12759 RPM Tip Speed 147 M/Sec Ant Vertical Disk, 17300 RPM, 206 M/Sec 99 Joules

Finally someone with proper test equipment! Cast silicone and urethane wheels.

Well done and we run the "Hound Wheel".I call them the Junk Yard Special. Love your testing! Thank You.

6:17 two bots + one in spares seems like optimal choice between bringing tons of spares and having no spares at all one bot in the box, one ready for the next fight and one to scavenge for parts. You'd have to get into two destructive fights back-to-back to really have to start to worry. I don't really have experience packing for combat robot events but for things I have to bring a lot of tools or parts I generally like to keep an inventory list with me so I can track what gets consumed/parts given/tools loaned to people and I have a checklist to make sure I don't forget stuff. Can just stick that box somewhere for the next time and just a quick glance at it will tell me what I need to order more for. Choice of container usually depends how you have to haul it: if you go by car and can unload right next to somewhere, just plastic crates are fine. However if you have to manually move it some wheels are always nice and needs to be able to close it in such a way nothing can fall out. If you're flying, you want something that latches securely because those people don't give a shit and they will throw the case as far as they can. Pelican cases are pretty much industry standard because they are so tough, have tons of room (and price to match it), but you can probably just get away with just a hard flight case if you don't want to pay that much. Really informational video, I like it of course when the production values are high with tons of editing but just straight put camera down and talk about stuff videos are great too.

We take everything that is out while we are building our bots as well...lol I go with the saying 2 is 1 and 1 is none. Great insight and video.

The random grunts paired with this video feel weirdly ASMR and I'm here for it.

Amazing design

I'm looking at how you structured the drive modules to see what concepts I could use to improve my own designs. One aspect you glossed over was how you constrained the drive motors without any fasteners. From the little bit you waved it in front of the camera, am I correct in guessing that you added something like a 3D printed key that screws onto the front plate of the gearbox, and then that key is used to constrain the motor in the drive housing and against the inner frame?

We use HDPE as well and love the prong nut idea. Awesome bot!

So I’ve been thinking about this some more. Could thin section bearings rpm rating be a limiting issue when scaling up to bigger robots? The counter rotator bearing is essential spinning 2x the speed. Big thin section bearings could be rated for a less than 5k rpm which kind of defeats the purpose of a high speed anti gyro

It was super cool seeing this thing at the TX aimbots event. This new design broke my brain for a second.

For V3 can you put a hub motor in the weapon :)

As always for you crazy compact and unique! Love seeing some HDPE here in the states, the prong nut usage was really creative! will definitely try them out on TPU, the drive pods are totally awesome. The new counter gyro is somehow *even more* innovative than MK 1 hound, and let’s be honest, a lot more sane, that said, I will miss that compact little hunch back, what do you plan on doing with it? It seems basically complete still. Also have you considered PTFE tubing instead of brushings on the drive? If your starved for weight that could save a little!

Oh my god we almost did the same exact thing! I have a teardown coming out in a couple weeks. Super interesting how we had different design choices to get more or less the same end product.

That's so cool! Counter rotator on the weapon shaft is really clever.

This is like Project Farm for robot folks! Awesome work!

How are the bearing/mini wheels for inverted driving attached? Is the upright threaded?

Another excellent video. You desperately need P R O M O S M!

Hi, I stumbled across your Hound videos a while back and was really impressed by some of the design features, and this project is also really cool! I've been trying to find and create more data about combat robot component performance, including traction, but your load cell implementation looks much more accurate than my prototype traction testing setup (using an analog force gauge). Did you make the load cell yourself or pull it out of something? I'd be really interested in the grip of wheels with molded Vytaflex tread and also molded silicone sealant tread. Another aspect that is really important but also extremely difficult to quantify is how the different tires perform after picking up dust or other debris. Perhaps you could roll a wheel through some "standard dust" before a test? Or alternatively, "prep" a wheel with isopropyl alcohol or another compound? If you are interested, I have some Vytaflex 40A wheels and the ability to make some 30A parts to send to you to keep for testing purposes.

I know they are heavier but I wanna know if skate or scooter wheels are good options

I knew there was a reason I subscribed to you. FANTASTIC video right there. Thanks!

these are super enjoyable vids, just finished watching it, had no idea your disks were mild steel, assuming AR400 or 500 now?

9:14 Now that's a lotta damage!

Oh also I was interested in the hubs you used for you drive. Are those custom? They are awesome.

Absolutely mental piece of engineering, can’t wait to see it In Houston! -CottageGore Robotics

Super clever design!

Amazing to see that system actually works... couldnever decide if it would give double gyro or no gyro. I also assume, given what you said, that you don't have to take your batteries out between fights in the US, and you can charge them in the robot?

been thinking of doing an anti gyro system for some time cool to see it in action.

I really hope you see this dude. if you watch the avatar series you'll be familiar with firebenders, I'm making a costume for Zuko and plan on using a similar idea to create "fire bending" I'm lost at one part, how do you keep the butane can continuously flowing, and what size/type of tube you used.

the beginning made me laugh... safety fourth right?
