Just now realised I never mentioned how heavy the ring was....... it's 110g of spinning, fighting opponents weighing 150g. Revolve is 225g due to it's shuffling pods weight bonus. Also, if you're in the area over the weekend, come check out Robot Havoc 7 at the Adelaide Showgrounds! We are fighting 150g through 5.6kg robots. I've got a brand new machine competing for the first time there too. Aside, I do now notice the stuttering in some slow motion shots. Still working out the kinks in this new phone, may trade some frames for audio in the future.
At the event mentioned in the video, we got to a point where no more fights could happen because almost everyone was busy repairing (no surprise most of the damage was dealt by James' two bots). Its certainly a good thing to have a challenge and also a high standard to aspire to. Even if that challenge often kicks our butts 😂
just in-case you didn't know, there are larger bottles of super glue (CA glue) usually in woodworking stores. comes in different thicknesses, and doesn't dry up in the bottle unless you leave it open.
ive left my 4oz bottle open for over a year now, and its still just fine. I dont know how, but it is, my last bottle didnt care that it was left open either, just gotta make sure to clean out the nozzle.
It’s amazing too see the process to assemble the ring. This video couldn’t have come out at a better time. It would be a great help in my process of designing my first 1lb battle bot.
I seem to have a knack for always fighting your new and improved robots first. At least this time I put up a better fight and we got the full 3 minutes. Revolve is super cool, I can't believe how much work goes into assembling it.
Using a shuffling system makes a lot of sense in a design like this. The way you've optimised things to exploit the weight bonus is very clever indeed. Lovely robot.🙂
you always have such unique ideas when it comes to bot design. Like... "hey what if the weapon... was the motor?" and then you make it and it's great because you don't have to balance the weight of your motor versus the weight of your weapon because they're the same thing. It's genius, you push the field forward with every upload.
New video!!! This robot was so terrifying and seemed basically indestructible for the entire event. Definitely scared for havoc. Also, that yellow bot seems dangerous...
As a response to your question at the end of the video, Revolve represents a relatively unexplored format of bot in its league, as far as I can tell. If anything the difficulty of unique projects is what makes them fun, since there's so much room to make up new solutions to new problems. That's how I see it at least.
I can see a ring spinner like this working very well with a small motor impeller and a skirt to suck it to the ground. Less weight to dedicate to the weapon and would possibly catch on the floor, but would be a big advantage to stop it getting thrown around like it's opponents.
As cool as that idea is, I don't think there's much room for an impeller, and there's definitely not any weight to spend on one. It's already 225g of robot in a 150g league, an impeller motor would be that many fewer grams for ring durability, drive power, battery power, or something. That said, some little fins on the ring might achieve a similar effect.
What I think is more likely then making the part from a large cylinder is that they started with plate stock, fixed it with a 4 jaw, then bored and faced it to dimension before moving it to the mill.
Something I would recommend is having a set of teeth that either have a taper to the impact head of the tooth, or just a thinner tooth with spacers. This should allow you to more effectively deal damage to TPU chassis as it will give you more bite and ripping and less straight impact force.
Mega. I love your channel - grew up watching OG robot wars back in the day and it was clear back then that stored energy spinners would always be the most terrifying things... and decades later I'm watching a tiny robot that weighs the same as the tablet I'm watching the video on smash things to bits. Amazing engineering, greetings from England :)
I've been following you for the longest time Jonny and honest, as a skater, you've been such a positive influence and attitude to the sport and on me. Totally down to support your patreon brother, but I had no idea you had one! Doing like a 10 second heads up that you've got a patreon at the start of your vids would be tops, and even sicker would be Jonny G merch. Maybe folks like woby can help for some premium gear? I feel like other skate wear creators in the space should try band together and build a new company. Berrics and Braille were cool and all, but for me the bits I froth are when the community comes together and combines their talents for one a other, and it's a little more homely than Pro™. None of us are gonna be Olympians, we all skate for mateship and health and happiness, and that's what you have in buckets. I hope you stick at it my dude, it would be a dark day without you and your creative and analytical approach to skating. Much love brother.
Great build! I think it's cool that you stuck with the same archetype, letting your experience and knowledge accumulate to make it the best with the newest tech! Glad you got connected with PCB way :")
I have to be honest, I have always wondered why no one put the motor on the outer rime like your design. It makes the most sense to me. On the outside you have more torque this way and its relatively simple in design. Im glad to see someone decided to do exactly this. You have a great design. I love it. Great job.
Quite a few shufflers here run tpu for the cams and feet, works great just needs upkept with grease. Added bonus tpu and urethane bond great for traction material
@@404-ThisUsernameIsAlreadyTakenthat's robot havoc 7 mentioned in the video! Largest event all year and revolve + other broken link bots will be there (:
This is easily the most advanced, complex and harder to build 150 gr bot i've ever seen. Pure madness. And to think it can be destroyed in 10 seconds if something goes wrong.
One note. Is not the neodymium that does not adhear, it is the nickel plating. Neodymium is very prone to oxidation and if uncoated will quickly start to turn to powder.
Are you using alloy steel metric countersink screws? Stainless steel screws have much lower strength. I'd suggest using a medium class alloy steel screw (Higher classes are more brittle -> bad for impacts). Also, I'm not sure it's possible with your current design, but you want the screws to actually clamp the tooth, that way friction from the screw clamping force takes shear load off the screw
It may also be possible to design the titanium rings to key into the steel teeth, like a puzzle piece. The screws would only really need to keep the teeth from moving axially, and have almost no forces on them.
I wonder if its worth having the teeth break off. The energy of an impact needs to go somewhere. A lot of equipment I've seen intentionally builds in shear points to prevent further damage.
@@heroslippy6666The teeth would likely go first anyways, but an intentional failure point may do its job a little too quickly. More likely than not, you'd lose some of the energy of a hit, the tooth would go flying into the side of the box, and then the rest of the fight has to be played by directly hitting with the ring. Plus, any judge's decision might take the damage to the weapon into account, even if the rest of the robot is fine. Doubt Revolve 4 would go to JD, more likely either hit or pit, but still.
Almost every big machine shop uses lathes and round stock as much as possible because its much more cost effective. As far as i know every part from Schunk is round stock for example.
In addition to basic round cylinder stock, they also make use of tube stock for parts like the ring where they would just end up cutting away the entire middle. It saves on both material and time on the tool.
Beautiful robot and great video, interesting thought but Protopasta does an iron filled ferromagnetic PLA that I've seen used before on custom motors, won't be as good as a steel backing but could be an improvement over the current printing material for motor strength in future versions. Look forward to seeing how it does at the next competition!
Have definitely considered using the ferromagnetic stuff, specifically a custom stator. I hear it's pretty fragile though, and not the best magnetic properties.
I use end mills with a radius on the corners because they last longer. Imagine the stress on a tiny, sharp tip when trying to cut titanium or anything for that matter. It's a very small point and takes all the stress, a radius does away with that stress point. Radius end mills = very common and doesn't mean the part was spun on a lathe. It would be very awkward to get that part in a lathe compared to a single operation milling run.
Magnesium alloy is also resistant to creep. Rings can be made addictively with a tig welder, lathe, & form. Would be hilarious to remove the pods & add ducted fans for a hovercraft version.
A type of bot yours might struggle with is something like BattleBot Chomp by Enfield Technologies. A smaller version in your weight class though. Having a pick come from above and spear your chassis would be pretty devastating.
Regarding your magnets, have you tried using magnetic field viewing film? It might help with identifying what magnets are in the wrong place, early on in the process.
@@BrokenLinkRobotics A clear plastic sheet and a handful of iron filings is likely enough to catch a backwards magnet. Just set the sheet over the ring and toss on the fillings. A proper viewing film would be better, but there are easy hacks for people with a bunch of metal shavings around.
We do a bit with magnets at work building motors for 6 axis stabilised gimbals. we use an epoxy called DP420 to bond the magnets to the backirons. Its pretty much impossible to get the magnets off with out using heat. We do sand the surface of the magnet to help with the bond. We also wind the coils with magnet wire that is coated with epoxy after baking them they are much stronger. I love this design. I would like to get into combat robotics but there is no meets anywhere near me.
Amazing build. I was recently investigating if anyone had used the weapon as the rotor. I was wondering if it could be made into a switched reluctance motor, so without magnets.
Very enjoyable to see the biuld and the combat. Was the max RPM mentioned? Also a crazy suggestion, make a second counter rotating ring such that the blades on each ring pass by each almost like scissors. A good hit could take a big chunk of the opponent.
Epoxy in general can be disolved by sitting in an acetone fume chamber. I.e. put the epoxy and a beaker in a bag or under a hood that doesn't dissolve from acetone and let it sit for a day or even longer depending on how much epoxy you need to remove. At least that's how we did it with out shoes when I was working with epoxy floor coatings and glueing prefabbed concrete profiles to the concrete floor. At least that goes for the types of epoxy I've worked with.
Hello, I know this video was posted a while ago, but I was wondering if you knew of any good ways to learn how to design those amazing shuffling pods? I am aiming to build a ring spinner (I'm sure nowhere near as successfully), and stumbled upon your video, seeing exactly what I was looking for. If you knew of any good places to direct my research, I would massively appreciate it! I appreciate it is a longshot asking you because I'm sure you're busy, but thank you for your time if you end up reading this!
Old idea but why don’t you mount the coils and the two guide wheels on that side on a sprung sheet . With the assembly being pushed out to the outer ring under constant pressure , you eliminate the variable coil gap and keep the guide wheels in constant contact.
Have you experimented using a R/C gyro to help stabilize the robot during spinup or moving forward? They are very useful on R/C helicopters, or R/C drift cars, but i haven't seen them used much in combat robots. One of the problems with horizontal spinners is they are generally very difficult to control during spinup or high speed movement, especially if slightly unbalanced. I think gyros could really help. Probably more useful for a wheeled robot, but you never know.
I absolutely love ring spinners. It's all the danger of a shell spinner but invertible as well. I'm 100% going to try to steal the hub motor idea for a US antweight at the 1lb scale, where the weight of a steel ring is less of a concern. What ESC are you using to drive yours?
what if you used shear pins for the outside weapons, if you get the right ones it would allow you to only put so much force on the inner magnet ring. It would suck to have it come off in battle, but i feel like it could save the rest of the bot.
let me give you a hint. get a tank rent or buy of Co2 make sure it has a pickup tube get some plumbing parts and feed it to the plate of Ti get below -20c and keep it there and your machine will cut just fine. also use 1 or 2 flute end-mills made for soft metals and plastics this is a rare case where a good old uncoated high speed steel will work a little better as it holds a sharper edge but it's needs to be cold -20 is just the starting point the colder the better
Maybe you should switch to 4 foot shuffle pods. They should have much better performance and be much smoother, the only tradeoff being a bit more complex and maybe slightly heavier.
What is the difference between shell spinner RPM and ring spinner RPM? I feel like the gearing/drive and bearing systems for ring spinners are massively speed limiting.
@roboman2444 it depends a lot on the design, usually you target a rpm and go from there. Shells are often direct drive at ant scale for ease of construction but anything bigger and they're geared down too.
If I only did the edges, would be left with a disc suspended by tabs or something that needs removing. Filing the tabs off would damage the smooth running surface of for the bearings
Obviously too late, but to help super glue adhesion on neodymium, you can lightly - and carefully - sand the mating surface. Love the new variant on the bot!
