09:10 The stability effect you're experiencing is called trail. It's like when you let a normal bicycle roll on it's own (or ride w/o hands on the handlebar) - when the bike leans to one side, front wheel PLUS fork steer and bike goes back in a stable position… as long as it's fast enough.

You'd want a small, light, maneuverable cart that's very open in the back so you're not banging your knees or the uni wheel into it and you don't have a hard time keeping it aligned with you. And not for any wheel bigger than a 12-inch, or you'd never find an ordinary shopping cart with enough room for the wheel. Also, how old were you? Were you at your full height? I don't have my old 12-incher anymore, but unicycles don't usually position you very low to the ground. I feel like, at my current size, the handle would end up about mid-torso, at which point any fall would dump me headfirst into the basket...

I never in a million years would have thought that could be made to work as well as you've demonstrated here. Astounding proof of concept!

Gosh, at 7:50 these look tailor-made for hurting your legs in the worst ways imaginable! I'm also surprised you managed not to gauge a nasty scratch in your car! Honestly, though it's very impressive how far you actually rode those rip-skates, I can't imagine turning or riding like that being used to usual skateboards and ripboards

Dang thats crazy James! You experimented a lot and really explored that field and came up with an interesting solution!

What an incredible way to showcase the freeskates! Awesome video James!!

This video escalated amazingly! Also, it made my knees, ankles, groin, and tailbone ache in sympathy for you, but that might be age talking. Great work on this one, lots of fun!

Im loving the evolution of the design process. Great work 👏

What a marvellously preposterous contraption. Love it! 😎👌

This is insane, you really are a mad scientist! Highly entertaining content, i had no idea where you get these ideas from

Years ago I saw some odd skates in an old magazine. Two children rolling along on one wheel skates. Each foot had a single large wheel on the outer side. There was a rod or platform to support the foot and a rod up the outside of the lower leg, strapped to the leg. The wheels looked to be at least 6" diameter.

i love how every stage of this project looks more dangerous then the last.

Adds turbines, removes helmet. 😅

DUDE!!!! THIS IS AWESOME. I LOVE IT!!!! ❤❤❤

I love my free skates! They’re quite hard but once you get it, you never forget… and the feeling is awesome with 100% control.

I really want to try this. How confident are you on a ripstick? Perhaps using the same technique as a ripstick will allow more control with more speed

word of advice for riding anything perpendicular to our body's symmetry . Keep you hips and knees slightly bent. I used to keep myself upright like a tree when riding stuff. Your whole body will fall over at once when you are standing up right. Make sure you know where the humans center of gravity is and how to manage it when getting in a good riding stance. I really love your channel and you have inspired my own robotics projects. I found the issue with mass when making scaled down version of a suspension design. Engineering is especially fun in that regard.

I bought a summerboard. It’s a skateboard with castor wheels under it. Rides like a snowboard. Took a while to learn, but now that I can ride it well, you essentially ride on the castors. It’s super fun.

I rally Love this, This could be used as benefit device and Militar help

I appreciate you going through the effort of building these instead of just learning to use normal free skates

Fun project! You should try moving under your own power like the ripstick which is very similar to what you have except the two platforms are connected by a single axle. On the ripstick you twist your hips back and forth which sends your feet forward and backward. The wheels draw a cross cross S shape on the ground as you propel forward.

10 or so years ago i had a waveboard, which seems similar to what you have except the two pieces were connected to each other. So maybe what i remember from that can help you here, to steer, you push your back foot in the opposite direction, not verry far, just about a foot or so, obviously, the further you push that foot, the smaller your turning radius. To gain momentum you would basically steer left to right continuously in quick succession. Hope it helps!

I remember coming across free skating over a decade ago when the trend at the time was a hubless wheel that when around your foot. I wonder if there's a decent way to turn those into a pivoted castor to adapt their design to this kind of design. With the much larger contact patch, and the other benefits hubless could provide, it seems like a good combination.

Got to hand it to you for not giving up... never laughed so much

Those jet thruster made is so exciting!

At 07:35 did you consider connected the two skates with a bungie cord to avoid leg splay? Could be attached at the shin brace level to prevent the cord from getting tangled in the wheels when your feet are close together.

Did you try the double wheels but using the swivel? I bet you could also add a second wheel axle that is connected via a very strong spring, but with an axle block at the top so the wheel doesn't catch on the deck.

i love how absolutely insane this is.

Hello from Australia 🇦🇺 this video was making me nervous 😅 happy to see you didn't hurt yourself

You tilt your ankles in opposite directions to steer on a ripstik. You can't do that with your cut off ripstik since they're strapped to your legs. You could get around this by putting a hinge or something where the strut attaches to the board.

Keep at the free skates, they're really fun! It took me just a few days to stay upright, and then a week to get going on flat ground. You'll really notice your legs getting stronger in ways you've never considered.

Now that you figured out the Ripstick skates use an angle to keep the casters pointing in a very helpful forward direction, would that work for your caster scooter, which you mounted flat to the board?

It took me a week to ride the freeskates. In some way it's similar to snowboarding. But freebord is the most similar. Anyway... Can you make a 4 caster wheels on an angle but wheel position like a skateboard?

That’s actually awesome, Those EDFs sound scary!

Brilliant and hilarious at the same time!

have you thought about feet that retracked up when starting or stoping or when you want to walk the feet drop down giving you a way to stand and walk could even add small wheels to the feet so you can start moving with them down and they pop up while your moving

So a revisit of the 1000W Caster Scooter with the 30 degree incline?

Cool design. You rode through the puddle like a champ

The surface on the ground changes too. The kitchen is smooth and the carpet offers more friction which helps

I was really surprised to see a Braille Skateboarding reference here. I just bought my first skateboard from them and have been practicing for a few days now.

That was quite terrifying :)

Thats my boy Jeff from JMK freeskates! So good to seem him out in the wild! ❤

In theory you should be able to translate your feet(as it would be sideways) and by design you should move forward. With forward momentum, the back and forth motion of the casters would propel you forward I would think. Add in the fans and even more speed.

I’ve realised that the most important thing to get used to is falling. Then you know how to do it without getting (much) hurt. But the parking lot at the end.. what a scary surface! Looks like a grader. 😳

The best part about this solution is the practicality.

How can I get those jet-powered shin pads to just work with my ripstick without having to learn a new set of prototype skates?

That turned out amazing!

I love how it just gets bigger and bigger and sillier and sillier as the video goes on.

Where did you get that EDF?

i was really thrown when you started making jet propulsion for the caster skates. It didnt seem necessary to me seeing how rip-sticks are propelled manually from swiveling your hips and legs. I would assume that while more difficult, the same principals would apply to the independent skates on each foot.

I think to steer it, you would have to twist your ankles axially. There's probably some resistance to that motion - maybe a shallower mounting angle would help? That self stabilizing mechanism is pretty awesome though. I never would have thought of that in advance.

Just imagine pulling up in a car park and seeing James Bruton skating around on his newest invention. I would loose my mind. lol

Bringing new meaning to the phrase "break a leg"!

are you able to speed up on your own by wiggling your legs back and forth? it’s pretty easy to do that on a ribskate, so i’m expecting it to work similarly on these

So there are electric freeskates out there. The brand I've seen the most is Summer board. They have powered castor motors. I wonder if throwing those on with a VESC would do the trick.

I don't know why but this is incredibly awesome. Maybe your best build

What I don’t understand about the split skate board thing in the beginning is how do you regain velocity? With a regular skate board you can use one foot to push off but you can with the split board because then it will leave you…

One thing i've wondered for a while is if you could have self balancing skates like Segway shoes or Boston Dynamics's Handle but on a human. One wheel on each foot, each actively tries to stay upright, some throttle control to either move them both together or control them independently, steering would be done by leaning, speeding up one wheel, or probably both. Never done more than just think about it, not tried to make it or anything, but it was a thought nonetheless.

"Let's take something easy to use like skates and make it harder! Also add jet turbines!" 😂 Absolute madman. Ridiculous fun. Thanks for sharing!

9:35 It’s also like a bicycle, true? If you’re falling one way on a bike, the angled front fork passively turns the front wheel into the fall, so the forward momentum gets the bike’s wheels under the center of mass again.

I've got an idea for a future project, how about fractal suspension? Like those fractal clamps, I saw someone made a fractal chair too, seems like it could be good for a rover concept

Braille Skateboarding cameo, yes!

Nice! A winning entry for the most innovative way to break your ankles.😂

Nope, only going along on a skateboard

you have so many amazing robots

When the only way to stop is: Crash or fall, I consider that a warning. So brakes must be added. When the only physical result is: exhaustion: A rest item must be added (seat). When the only apparent steering used is just to keep going straight, and not fall: A steering mod is needed. Congratz, you have reinvented a mini--bike. BTW I loved the attempt, and excellent video. But you do need a support team, including a medic.

These seem like a great way to test wether your knee will break before your ankle snaps or not.

Was there a center of mass issue causing the turbines to be mounted on the same side?

it was interesting to see james slowly approach a ripstick. like you could probably edit a ripstick underneath him in the final footage and his movements wouldnt be far off. the funniest part is you could for sure go faster on one, with no engines.

What about using something like ski poles to gain momentum and add stability

Could you make a Jet fighter based on this rollers please?

Steering solution- look at the Rip stick for inspiration again, and make your lead wheel fixed instead of a caster. May make starting harder, but will work as a guide wheel when you twist or lean over it, once you're going.

I don't know what kind you've ridden, but the only ones I've seen have a rotating caster in the front as well.

I think you might be able to turn by shifting your weight. If you put mere weight on your left leg, your left knee will bend, tilting the front castor right and therefore turning right. The opposite would turn the rear costor right, causing you to turn left.

If it is like the ripstick you turn by angling your feet in different directions. Lead foot leans into the turn (like a skateboard) and trailing foot leans away from the turn (opposite of a skateboard).

Haha that's cool! Maybe you could apply the 30 deg mounting to the caster bike as well? And maybe lower the standing surface while you're at it.

The way the "rip-stick" worked was by allowing you to rotate your hips to steer around your leading foot. So to make a left turn, i lead with my left foot then rotate my hips so that the back right foot swings from behind, redirecting my forward foot. The way it propelled was by allowing you to essentially rotate your hips to 'push' off the ground. Like self propelled snowboarding, you steer with your propulsion. Since your propulsion was essentially staticly oriented, you never had a way to control.

Interesting to see RealVNC advertising. :) In the past, I used VNC extensively as a disability aid, allowing me to lay down or sit up as needed without changing what I was doing. Had to give it up because using a laptop in bed was killing my neck. Touchscreens were better for me, but all of the software I used was absolutely terrible on touchscreen. I kind-of should have adapted that one self-compiling IDE-compiler I was using, but wasn't happy with its coding language. A Raspberry Pi wouldn't be a suitable component of the system anyway.

You fall more safely than I ever could, sir.

Wow. Thanks for trying those skates so that I don't have to. I was very tempted until I saw how hard they were to use.

Heelys exists for a reason... I love his attempts at these things!

So what happens if you have one wheel on a caster and one wheel that is solid

I did not laugh so much for a long time! Free skates take some time to get there, but it is doable, keep at it! ;)

what if you tried leaning forwards and back while accelerating with that?

I will say, I own a pair of largely unused Freeline skates, and the freeskates you have have much more boxy wheels. The JMKRide freeskates have an even more rounded profile than their original design which I think helps considerably with turning. You also DO tilt your ankles a lot to turn on freeskates, it's not just yaw, which is why I think the square wheel geometry is hurting you

James' ankles: blink twice if you need help!!

I am more worried his knee caps will pop out at some point (yes, that can and does happen to people).

I have Crosskates. Big huge things, too heavy really. The front of the two wheels per skate self steered, through a self cerntering resistance. Lean is steer. Much like downhill skis I guess although I never tried those. Also allowed for double push skating which was pretty amazing.

How much thrust do the EDFs output?

Lol imagine how ridiculous the Wright brothers looked... until they started flying! Keep creating!

What’s is the thrust per edf ft/lbs
