I recently discovered freeline skating or free skating. These are skates which each look a bit like a little skateboard. They have two wheels each but they aren’t attached to your feet like rollerblades or rollerskates, you just stand on them. Free skating is really hard, but I can make it easier with less wheels and jet engines? Caster dynamics are really interesting - the physics involved mean that skates with caster seem to automatically stabilise through a passive-dynamic system which always pushes you upright provided you can keep moving. I 3D printed some pieces and used a CNC to make the main skate platforms.

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.

@Amanda-C. 5 месяцев назад

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...

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.

@jerredshifflett6287 11 месяцев назад

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.

@one-man-band 6 месяцев назад

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.

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.

@TheRealAlpha2 11 месяцев назад

I'd say go back and watch some of those Braille skateboarding videos, after two tor three episodes of them falling on their butts learning rips-skates and free-skates you almost absorb the understanding like Neo in the Matrix learning kung-fu. Granted, I think for either of these you need strong legs, but still impressive that you basically made electric ripskates out of necessity.

@tubbymitchek 11 месяцев назад

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.

@futtymad 11 месяцев назад

Brilliant and hilarious at the same time!

@CandC68 11 месяцев назад

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.

@djdt_614 5 месяцев назад

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.

@ankokuraven 11 месяцев назад

@TheDutchMagicTeacher 11 месяцев назад

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!

@victorro8760 11 месяцев назад

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.

@jimysk8er 8 месяцев назад

just a reminder that with roller blades you make pivoting your feet easier by transferring your weight onto fewer wheels to unload friction and retransfer the load to apply friction to turn. in reality its more of a balancing act between the two. the saving grace is that you have the option of always having two stable wheels to rest on an some limits to movement. the rip stick works because the distance between the pivot points of the casters is fixed. the amazon skate things always have at least two wheels touching the ground and your side to side movement is restricted. these all somewhat act like a sailboat where the keel restricts the tilting movement thus transferring the forces into the direction where it has freedom to move.

@xaytana 8 месяцев назад

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.

@eekee6034 5 месяцев назад

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.

Whatever else... kudos for putting yourself through that torment. I used to be a pretty good skateboarder, i'd probably be now, the old guy who wipes out trying to show the kids a cool trick, but when i first tried freeliners, i fell over several times until the guy who borrowed the set told me the secret. You need to forget about them being skateboards or skates. They're neither. It's less about continuation of motion (which is the core element of those two) and more about static balance that allows you to move in a direction. It's like that trike that was popular for a couple of years many moons ago, the one where you'd lean left (which would twist the trike body) then lean right, then left, then right and that would create a forward motion. It's similar in that respect. You're using your static balance to create motion.
