As a full time wheelchair user, I cast a very skeptical eye at said "annoyingly infomercial-style video". About the only places I have trouble are in soft gravel, sandy beaches, and deep snow. Certainly not gentle curbs and flat lawns.
The gantry was to work by building a framework, with rails constructed from 1x1 blocks. The gantry X/Y axis arms are to traverse the rails with wheels. There would then be some pistons for the z axis, a rotor, and finally a landing gear for grabbing. All pretty straightforward stuff. On something like this, you do not want suspension on the wheels:

The Global Air Cylinder Wheels team has also sent us a bunch of video detailing the advantages of a much smaller scale ASW for wheelchairs. Because of the built-in suspension effect, you'd likely experience more ride comfort, as well as a vastly superior ability to negotiate uneven ground without any of the wheels lifting off and losing stability.

Loopwheels have developed a robust wheel with world-class suspension that works at higher speeds, for use with power attachments. The springs utilise hi-tech carbon composite materials and are available in 2 spring strengths (Regular and Stiff), which will allow customers to get the best comfort and health protection for their weight and the typical activities that they undertake. Weighing under 3lbs (1.36kg) per wheel, and removing much more vibration than any other brand of a wheel, it is the definitive wheel if you love travelling faster on tracks and off-road. Made in England Loopwheels are vibration reducing wheels. Integral suspension gives you a smoother ride.

The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel.
'I suddenly wondered why the wheel couldn't have its own suspension, and quickly drew the idea down - and then did nothing about it for two years.
Currently, this is just a concept with renderings, no prototype or production is planned.
When driven wheels are independently suspended, the differential is fixed to the frame and drives the wheels by jointed drive shafts.
They didn’t even mention the rim profile, surface treatment or wind tunnel results. I mean come on! Call me when there’s an aero version. Maxx on May 20th, 2016 - 11:05pm
Take your trial wheels for a spin. Try them out on roads, cobbled pavements or grass and feel an incredible difference.
There are two basic types of vehicle suspensions: independent and solid axel. The main difference between these two is that both right and left wheels attached to the same beam i.e. solid axle, while independent suspensions make provision for one wheel to go up or down without affecting the other wheel.
Worn, weak, or bad shocks and struts can also affect your vehicle stopping distance by up to 10 feet. Furthermore, they place excessive pressure on additional suspension components such as your upper and lower ball joints, tie rod ends, and bushings.

Trike Asylum archival and resource material for human powered recumbent tricycles
When I refer to this trike as such, the word “ultimate” seems to annoy some people. They ask questions, such as “Where do you get off, calling this the ‘Ultimate Sprint’?” They ask upon what do I base that description, isn’t it just a matter of opinion, and so on. When I finally get the chance to just say: this is the trike that ICE put in its “Ultimate Collection”, they just look momentarily lost for a comment, then eventually just nod. And now that we’ve got that out of the way, let’s look at this trike, OK? Vinyl Graphics from the Flaming Eyeball Posted on July 17, 2020 by Larry Varney
Designed for spring gears, the Shock Wheel™ system absorbs energy at landing and taxiing. It mounts very easily between the gear leg and the wheel axle.
With scores of iterations, and hundreds of man-hours invested in the final product they are undeniably good-looking wheels, at first glance (and second glance, and then just staring at them) they wouldn’t appear out of place on a BMW concept car – but this isn’t pie-in-the-sky, these wheels are here and, thanks to their Kickstarter success, very much NOW!

The front wheels must be free to pivot on their steering swivels. The driven wheels, whether front or rear, must also be free to rotate with the drive shafts .
When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps.

Much better to start with the wheelchair and bicycle markets, which are easier to break into. “Most of the world’s wheelchairs are used in hospitals, but there is a large premium market for people who want to live active lives but are restricted to wheelchairs by their disabilities. These people want to be as mobile and self-reliant as possible, and our technology makes this possible,” said Barel.
Considering all of the technological advances made in bicycles, cars and trains; the humble wheelchair hasn’t advanced very much since the first one was invented for King Philip II of Spain in 1595. An Israeli startup SoftWheel is about to change that with a bike and wheelchair wheel that is more comfortable and more efficient.When an unfortunate accident left Gilad Woolf with a broken leg and dependent on a wheelchair, the farmer had first hand experience of how uncomfortable wheelchairs can be for the millions of people who rely on them for everyday transportation indoors as well as outdoors.
“Selective suspension is the key to the mechanism because constant suspension creates loss of energy, making pushing more strenuous. Only when encountering an object does the suspension system activate, making the inside of the wheel, the hub, move and absorb most of the shock instead of the wheelchair user’s body,” she said.

Bicycle wheels often follow a standard convention. They contain metal rods known as spokes that radiate from a center hub. The spokes provide strength in all directions as the force of the rider bears down on the wheel. The design of spoke wheels hasn't changed much in the past, but Chet Baigh has a new approach.
With every rotation the springs will bend and absorb a amount of energy. Normally this is called “damping”. Its pretty useful in some cases. But it’s pretty unusual to damp a rotation of wheels, because this will slow down the straight moving. For Bicycles (and all other vehicles) you should mount your springs in the direction where the impact is coming from plus a additional damper to stop the bouncing of the spring.

On the plus side, it's a really nice looking bike... very frustrated with it though....
I played with the idea using steel springs in wagon wheels for a Ring of Fire series fanfic (I highly recommend the books if you like time travel stories) but I am not convinced that loopwheels are a better solution than a springy seat post.

In today’s full-suspension mountain bikes, the front and rear shocks do excellent jobs lessening those impact forces. And that helps keep riders logging miles and turning switchbacks.

Technical ArticlesRear Wheel Drive Suspension OverviewRear Wheel Drive Suspension Overview Cameron from IPD goes thru the suspension components of rear wheel drive model Volvos and explains the basic setup and identifies the primary parts. "All right Cameron from here and today we're going to talk about some of the basics of suspension on a rear-wheel drive Volvo what the main components are where they are and what you should look out for. Here on the lift today we have a Volvo 242 so we'll talk about the main components on the front of it. First a lot of this is very much the same as you'll find on a Volvo 740 or a Volvo 940. As far as the front strut assemblies going and what the basic components are, even though they look a little different in those cars this should still give you a good idea of kind of where everything is and what it does. Looking also right here what you'll see is this, this is the sway bar end link bolts here to the control arm. This goes up and attach this to the sway bar right here which then goes across. Sway bars up you should be pretty familiar with on your car because it's IPD's flagship product and we've got huge upgrades for these that make the car handle ten times better and make it a whole new car. That's kind about it for the front it's a pretty basic suspension system there's just the control arm, ball joint, strut assembly, sway bar, and end link and the associated small pieces like control arm bushings that are here and here. Looking from the other side of the rear end of the car to show you some of the other components. We've just got a couple more pieces that complete the rear suspension system. This one is obviously the coil spring it is mounted on the back of the trailing arm here. If we follow that up we're going to see what is called the Panhard bar what its job basically is to locate the car over the rear axle. If you watch it here it bolts through the chassis of the car follow it down this way and it connects to a bracket on this side on the actual rear end. So, it's what is suspending it left to right and holding the car balancing it left to right over the rear end of the car. That's about it for the suspension very simple setup on these Volvo 740s and Volvo 940s are a little bit different but the basics are pretty much the same they use the same kind of components and hopefully, this helps you identify what's under your car you know what you're looking at any education is always going to help you maintain your car better.

For me, base on this design, as long as you can maintain the hub to be: ground to hub distance would always be greater than the hub to the horizontal distance (radius) to the rim. then you should be fine.
