It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.
With standard quick release axles, a choice between 12mm or ½ inch bearings and available in 24″ and 25″ sizes, Loopwheels fit most manual wheelchairs.

Less effort is needed to push over uneven pavements, cobbles, grass and gravel paths and it’s easier to get up kerbs too.
"Price on application." Not good news for anyone who wants Extans' Akhal Shadow Bike for anything more than a pipe dream. Or a photo on their desktop. But even as the latter, you have to admit this bike, inspired by the...

Things turn even further in the favor of the ASW system if you factor in punctures, blowouts, tire fires and how long a truck has to be out of service each year while those monster tires get changed. ASW treads are bolt-on, bolt-off chunks that can be changed with very little gear, without even jacking any wheels up, and done in sections during shift changes and lunch breaks so the truck's never out of service due to tires. They can also ship much more cheaply, since the whole assembly can be broken down into bits that easily fit in a regular shipping container.
A set of ASW wheels, on the other hand, will cost you more upfront but last something like 13 times longer – out to the service life of the truck itself. Your first set of six wheels in this case will run you about $1.705 million, but over 10 years you'll likely only need two tread replacements at around $55,000 a pop, giving you a 10-year budget of $1.815 million and a $845,000 saving.
Impact and vibration are a common cause of discomfort for many wheelchair users and we are excited to be spreading awareness of such an innovative brand who are tackling this issue head on.

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.

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:
