Double differential steering 

This has the clearest explanation of how this system works. Thanks very much. I’ve subscribed.

That is a lot of work there. Thanks for sharing.

never take this video off RU-vid as i need it for when i get the money and start the build on a rc tank of the 1/10 scale also plus its educational as well

Hi. Nice video. May I ask a question? Motor M, the pink one, how much power is required here relative to the main motor. One minute I think it only needs to overcome the friction in the drive train, than, once I think I have it, I begin to believe that it needs a significant amount of power. Thank you for the help,

So have you looked into the Voith-Schneider propeller system yet? It would be interesting to see how it works in a computer simulation.

Thanks for the excellent video...just a question..when it comes to speed calculations, its clear but when it comes to torque, while turning, we have a torque from the axle (i.,e) blue sun gear which drives the planet gear and also a torque on the planet carrier (from the steering motor) which drives the violet satellite gear, so we have two torques propelling the violet satellite gear(one from planet of blue sun gear & another from planet carrier) so what will be the torque on green shaft?

Just confirming: The 2 yellow spur gears are of unequal size? So they acheive the same ratio with the respective annulus?

Thanks. I enjoyed this very much.

Should we use a warm gear under the M motor if we don't want different surfaces under each side to cause a turn unexpectedly?

thanks for the great video, do you have any recommendations on where i can learn how to analyse the speed and power outputs of each shaft? basically i am trying to calculate what kind of power i need the steering motor to have when compared to the engine i.e how does the ratio of power between the main motor and steering motor effect turning?

Thank you. Very good animation. :)

So how are the green gears stopping or how could I make them stop? I'm trying to design a chassis for a robot by using only one motor and could really use the help

Nice design. couple of questions though, the drive torque output is equal on the steering planetary gears housing? Meaning, the steering planetary gears housing will not rotate in the event if drive input / output torque increases. and incase of drive input stationary, does the steering when it on move motion will rotate the drive input? I've been searching for a while for a double diff steering design that will cancel / equalize the torque on the steering input. As you know, regular double diff steering will force the steering input to rotate incase of torque increased, which can be fixed by worm gear steering on the diff housing, which is not practical. Thanks.

I count 21 gears total, is that correct? Man how complicated just for steering!

Very good video.

What should I do if I want to operate the gear in Autodesk Inventor?

I think this could give a smooth turn curve on road. like the output of differential.

¿What would be the power of the orange motor with respect to that of the drive motor?

I built one of these with meccano a few years ago

Nice👏👏

Hey Thang , i like your videos very much .... Do you have an Idea for a toolchange HSK 63 to lift up and turn around 180° to put in a spindle

It's called the Gleasman system.

What software is this with? Love the content

hola thang felicitaciones , asombroso . eres un GENIO !!!!!!!!!!!!!

Yeahhhhhh my invention would cost too much to make it work. I thought it'd be more simple until I drew a sketch and did some research. Back to the drawing board.

What would M be then?

Lego substractor!

If engine is rear, for turn left, "M" must be can change rotation direction. That is problem, if engine "M" is mechanical. I think that have electro motor and mechanical engine. Electro motor must be have so many force, but for brushless motor that is not problem.

Sir it's manually tracing but I need auto tracing machine

You have a caterpillar tract example ?

Wow

Sir how to make auto pantograph machine for 7:1 ratio duplicate engraving on iron. Like reduction lathe machine

What is "M"?

Komatsu hydrostatic steering system (HSS)

Cela s'appelle des différentiels asservis....... inversion du sens de rotation sans perte de puissance, sans usure, sans friction...... connu depuis 150 ans..... sorry my writting!!...
