If you had a flywheel geared to drive that main drive gear and had a small motor running at its most efficient speed, then instead of the neutral space on the sphere gears, have it somehow take that inertia of the wheels back to the fly wheel you could have regenerative breaking and then the whole think in theory could be quite efficient because it would overall be driven by a very small light weight motor?

Given the motor spins continuously I wonder if you could use that as a gyroscopic stabilizing mechanism

@jasonthomashorn4794

3 жыл бұрын

Interesting, I doubt with the weight required for gyroscopic stabilization the power loss when engaging the drive wheels would have that much of an effect. Seems do'able.

@harrisonmc123

3 жыл бұрын

I believe fly wheels must be untouched in use for stabilization. If a heavy weight were to be attached to the output it would give a reaction wheel effect that would be counter intuitive to the robots movement.

@jasonthomashorn4794

3 жыл бұрын

I was thinking that as well. But the cvt's would always be spinning even when the wheel was in neutral so changes in fly wheel would really only happen when engaging and dis engagement. Especially if it was inverted and the flywheel was under slung. But then there is the speed of the flywheel to consider. Would need to recalculate reduction to the wheels.

There is one downside to its use on this particular testbed style of machine - as there is no braking options that wheel is free to run so you can't 'turn it off' and steer around it 100% predictably - its a very neat execution of the mechanism don't get me wrong, but on that tank steering testbed the clutch freewheeling can lead to steering troubles when you wish to turn around one side or other and the free wheel just rolls so you instead get an uncontrolled veering in the direction you want (as the free wheel still has friction and resistance) - simple enough to avoid in practice if you can accept not being able to just turn the one side against a stopped other i.e the very tight radius but not 'on the spot' turns - as in effect it can only turn 'on the spot' (reversing side B from side A) or at any of the wider radius when side B is just solidly engaged and side A is however much faster you desire to create that radius of turn. Add in a brake for each wheel and that trouble goes away entirely too.

This would be a great setup to use for a huge steam or gas engine powered robot. Something that the power source would not be as responsive as a stepper.

Yeah, the engine would only need to maintain constant RPM. The CVT wheels would translate that into useful motion. If the same engine could generate enough surplus power to run its electronics and servos you'd have a pretty long range robot.

Now that sound awesome to make.

The robot arm idea is really interesting! It reminds me of old sawmills, where the equipment would clutch in and out of the main waterwheel which delivered power via a belt and pulley system going through the building. For the arm it means you’d only need one strong drive motor rather than a motor at each joint - that definitely shows promise!

Is this the most practical way of making wheels turn at different speeds? No. But is it the most FUN way? Definitely!

Deeply neat. Thanks for exploring these new wheel and transmission designs.

I really enjoy these proof-of-concept videos!

And I know my CVT comment on the previous ball video probably didn't influence the creation of this bot. It would be a natural progression to do this one. But it's nice to think it might have. Well done.

Always coming up with something new and I am here for it! Really interesting system, visually very cool and mechanically fascinating.

The final robot is super cool! and seeing the servo arms swinging back and forth to control the robot is very cool and a little mesmerizing.

Wow!!...Crazy concept. You are truly a genius. Your thought process and overall implementation is so inspiring. Keep up the good work.

Impressive as always.

For some reason I was researching this same cvt system earlier this week. What a coincidence you made one as well. Great job. I think it could have a use for a steam power or even gas powered robot. It would really shine if it was 6 wheeled, all direct driven by a single belt and the same 2 servos on a single motor. It could be a great drone vehicle with gas it could run for hours and miles in this configuration.

I'm amazed at the consistent high quality of your videos

I am most impressed with the demo of this, well done. Also, excellent music used in the demo too.

These sort of mechanical solutions to common ways to do things make your builds really fun to watch in action.

Very good James. Your projects are amazing.👏👏👏

I've got a bicycle with a CVT-it's pretty fun. In fact, that sphere-based CVT video you showed is by the company that designed the transmission on my bike. The CVT gearbox is called “Enviolo”, and the bike is called the Priority Continuum Onyx, if you're curious.

yea, i've got one of these CVTs on my bycycle...'nuvinci harmony' now enviolo... fully automatic...awesome.

That is such a genius design, WOW!!!!

So much awesomeness going on it's hard to keep up in a first watch through but this is a great video!

I am extremely impressed you are an extremely smart man i never would have thought of that, and that's why I love your videos Thank you

It looks pretty cool when those arms move!

I often wonder if, when James comes home after a day out, several of his robots greet him at the door and say "Home again home again, jiggity jig! Gooood evening, J.B!"

This clutch is nothing short of brilliant! Love the idea of a mini robot with these fellas on!

As always brilliant I love your videos I get sometimes headaches how you do it. :-)

This setup would be great for an internal combustion motor based robot since that's usually constantly running.

That's such an awesome design, can't wait to see it evolve even further. BTW, maybe using small cycloidal drives instead of the servos and arms to change the tilt of the hemispheres I think it could give a more compact and sturdy fit, if placed by the side of the hemisphere's holder, though the current arms design look interesting, looks like there's someone inside manually driving it :D

Very impressive - as always!

That's an interesting robot, congratulations 👍

Very pretty mechanism! Thanks

Amazing Video 👍 love your work 😁🙌

This is so satisfying to watch it work idk why but I love the arms moving the balls

This is a nice little piece of mechanical engineering. Really awesome how it works. Maybe use a set of clutches on a drive shaft like you suggested to keep the motor weight down and close to the center of mass and then use it just for a hand, like an improvement on your Ultron robot's hand.

Love the music for the drive test :)

Genius man thank you for sharing !

OH MAN!! Just another 9 more subscribers and you will have 1 million. WOW! Congratulations when you do. You been doing this for a long time. Congrats and enjoy 👏👏👏

Now this is an interesting design! GG!

I'm sure the frictional losses in this thing are quite high. There is essentially 3 places that motor torque must pass through to the wheels. This is an amusing and clever build that is driven from a single motor.

It's like a regular two wheeled robot, but with extra steps! Super cool.

Genius ! you are a genuine Genius James !

way to put it all together very cool !

very clever idea, I really like this one.

The back little wheel just standing there... *M E N A C I N G L Y*

Dude you’re an absolute genius

Fun stuff as always! You might want to lay out a course or something for your demonstrations to prove that it's really controllable. Seeing it flail around your kitchen doesn't really show that it works, aside from the fact that it doesn't hit the cabinets, but I think it would be a powerful visual to have a track or line or something to really demonstrate controlled motion. Doesn't even have to be fancy, just tape on the floor of a big room or something. Love your work!

The moving levers gives robot steampunk quality.

Good work!

A neat real world application for this sort of transmission might be a gas powered robotic lawn mower. Could use the already steady running gasoline motor for the motive force, and only need very minimal electrical system for the servos. Super neat.

This is a cool design. Thumbs up. 😁👍👍👍👍👍

That is fecking awesome

Very cool idea! Looks like some folks beat me to it, but this seems like the perfect setup to use a flywheel to drive the system instead of a motor. If you make a 1 or 2-wheel robot (1-wheel would be awesome!) the flywheel could potentially double as a gyroscope to help you stay upright.

Awesome final result ^^

This is brilliant!!!! I'm not sure in how far this is patent-able but as robots go this one will go far. The limited amount of moving parts. The load-bearing moving parts.... Man this has a future. I kid you not. As an example I see this riding on mars but also as a more sturdy Roombah. Just imagine this clutch system adapting to different types of flooring by using the clutch. Not just the wheels but also the brushes.

Looks like a modified version of the drive system used by "zero turn" riding mowers? The gas engine turns a flywheel at a constant speed and variable reduction transmissions control each of the two drive wheels, allowing forward and reverse at a range of speeds.

@AlRoderick

In reality zero turn mowers use two independent hydrostatic drive mechanisms, hydraulic motors powered off of a common pump, the drive levers are connected to valves. Most ordinary lawn mowers with steering wheels have a single hydrostatic drive these days, much easier to use than a conventional transmission when you want to have variable speed and don't want to be messing with the throttle and therefore changing your blade speed.

@eulachonfish

3 жыл бұрын

@@AlRoderick Many zero turns have a pair of independent sealed hydrostatic drive units that are belt driven. A single belt drives both input shafts directly from the motor, and control arms attached to the drive units control their ratios much like the design in the video. The actual reduction mechanism is very different, involving movement of swashplates that change the displacement ratios rather than changing the flow rate with valves. Since they don't have the restriction of valves they are more efficient, and much like a torque converter tend to work great until they don't. I've rebuilt them before for customers and currently own a mower with this system, but my next one will probably be the pump/valve/orbital motor style just because it removes the reliance on proprietary parts (Deere, of course)

Wow, that looks incredible.

This would probably be more important for motors who like specific RPMs, like ICEs.

Very cool. Thank you for sharing this. I think a small improvement would be to make the ball portions a rigid material with surface texture for grip (not flexible), then have replaceable rubber bands on the drive and output disks. *I think that will wear more evenly *be easier to replace without having the original model (later maintenance/rebuild concern) *be less prone for inconsistencies in movement between the 2 sides

With those two levers on the top, it looks like a strange version of a steam locomotive. Really cool! :)

It works great! You can also use a flywheel instead of the electric motor and still have excellent control
