This thing gave me a bit of an idea for a project.

Take two of the spoke-less wheels and you have a good platform for a touring size segway vehicle.

How reliable a suspension system could be simply designed for this?

What is the most reliable fail-safe system to any foreseeable component failure?

Who wants in?

Must must have good electronics. In particular the mathematics of optimal damping is an absolute must. The problem with these big wheels tends to be braking, and that’s because the brakes are applied too quickly. The problem can be fixed by rapid electronic control of braking strength.

How much is that already within the segway software?

I suppose that depends on whether you are going electric.

Good question. Big wheels have greater angular momentum so the braking strategy would have to be different. Both small wheels with high centre of gravity and big wheels with low centre of gravity can be made stable, but in a different way. I doubt is there is anything in current Segway software to stop the motion of a pendulum, but it should be relatively easy to modify the software to include that extra concern.

For high speed braking I’d drop a smaller wheel or two out the back and incorporate a suspension collapse that brings those wheels out and tilts the cab back on the main wheels.

Just had a thought moll. Where the Tumbler pulled off a really believable Bat vehicle this thing could pull off a comparable Robin machine.

Speaking of pendulum, if you are aiming for high speeds, would it make sense to shift the cab weight forward of centre with torque load?

Anchored to the rims to the rear but rails forward and probably up a bit to maintain balance at speed which allows the rims to be rotated off axis for high speed turning, I think?

Could be, like the extra wheel on a drag racer. I’d like to try with just the two big wheels first though, at least in theory.

Have you looked up the original single big wheel jobbie where the driver sits inside the wheel?

Yes and seen the bark it takes of big burly bikers when it gets the wobble up.

Hence the need for electronic control. Braking ought to be the exact opposite of accelerating. Accelerating always works well, so electronic wobble control on braking ought to as well. But steering in one wheel without wobbling also has problems.

So starting with the basic cab-chassis makes sense to go electric power but that can obviously be supplied power from a generator. I don’t foresee any issue with the software required to convert from thru axle to pendulum gyro-stability. Where I see issues is with high speeds-suspension, cornering and braking synchro. Since a fail-safe mechanical system is required to manage software crash I thought extenda-castors and a cab positioning system that works on torque so that loss of power withdraws the cab and extends the braking wheels in a manner that maximises stability.

Instead of messing with offsetting the centre of balance in that manner perhaps pivoting the rims so that the leading edge draws together like the old snow-plough? With software designed to incorporate this would that maximise braking stability in a controlled fashion?
