The main benefit I can think of for the military is the ability to approach zones that have anti drone equipment via the ground. Noise isn't really a concern since grenade drones fly too high and kamikaze drones rely on speed and unpredictability. Not sure how much better approach on wheels would be than just flying low, either.
The tradeoff is presumably higher cost and less reliability. Additionally, less ability to carry mass than if it just flew.
I can't imagine a way this would be too useful but obviously a lack of imagination isn't proof..
The obvious weakness are the wheels. Conventional infantry are already trained to hit armored vehicles in the wheels/drivetrain to remove their mobility. Hitting a wheel for this robot accomplishes the same for driving and flying (since the rotors are part of the wheels)
Although I don't think militaries would really rely on wheeled transportation much for drones, though perhaps reduced battery drain in the wheeled on-ground mode is a selling point for longevity in the field. It certainly has many other uses though.
The driving to walking transition is pretty darn cool. Using the propellers to lift itself up is pretty smart. But overall, this seems like an absolute reliability nightmare.
The good news is that when the battery dies, it has no moving parts!, keeping it simple.
EDIT:
What would be really neat ; putting little inflatable pontoons on those skids.
That thing is awesome, however, with the hard plastic wheels, and the way it scapes them back into forward wheels, I feel like this is a dead-in-the-water-flaw.
Imagine trying to scrape the wheels back into place on sand, or any other terrain obsticals that will prevent the pulling the wheels in.
Instead, it should move the pivot joint and allow for the wheels to be lifted up, gull-wing-style, then straightened and then placed down like feet, lift the body, then drive....
That thing will die in water without pontoons (the wheels/tyres maybe) -- and also not relying on scraping hard Big-Wheel stile plastice tyres along whatever surface.
It’s probably a one use disposable solution when something critical needs to be delivered somewhere, be it peaceful (medicines) of bellicose (explosives) or anything in between.
Unpopular opinion.
Sometimes I look at university projects like this and I struggle to differentiate what is really innovation vs what is just grownup kids having too much time and money at their disposal.
Haha, saying post docs have too much money is amusing!
They have time, because they accept lower remuneration for many years to work on things they are interested in.
All of this research has to get funding from somewhere. Presumably the funding bodies decided this was a potentially useful thing to fund.
So I'm not sure what your complaint is really. Are you unhappy because you personally don't see the value in some research? That it just looks too much fun to be "real" work?
Not all research is fund through grants. Additionally, not all grants are optimising for real world impact.
Not saying that this is bad.
I just wonder if those post docs were put in a business context with the same runway of money, but a more strict business outcome as success criteria, would focus their work on the same things in the academia.
I'm also realising, as I'm writing that this is a very well know objection to industry vs academia, and possibly my knowledge is limited enough that I'm most likely wrong :)
Neat. What I want to see are close-framed, 15 mm thin, 75 g max, 4 wire, ultra-quiet lift modules 20x20 cm to move through buildings at/below background noise levels. vcc, tach, control, and gnd. Toroidal designs show some promise in 3D-printed composites, perhaps of the "flower-Moebius" 5-7 large double blade design with a long chord.
Agreed, the headline is a bit misleading. It can fly, roll on 4 wheels, or roll on 2 wheels.
The latter is interesting, but doesn't constitute "walking", especially when the point of walking (as a preferred method of locomotion) is to be able to step over obstacles or onto platforms like stairs, which rolling on two wheels obviously can't accomplish.
> Joints on the wheel assemblies allow M4 to execute a walking motion. In M4's current iteration, the walking motion is mostly proof of concept. However, with anticipated advances, future M4 generations could possess the ability to effectively walk across broken terrain that a wheeled robot would struggle with.
Except that the provided demonstration isn't walking any more than using a Segway is walking.
I noticed the terrified terrapin at 0:40 in the video as much as anything else! Impressive idea though, being able to be multi-modal. It'll be interesting to see how quickly that is copied and made available to Joe Public.
Tricopter slash tricycle design may work better for swimming. The 'rear' wheel could have a controllable axis of rotation. That said, we have hundreds of years of propellers getting caught in seaweed. I don't like the chances of a lightweight drone resisting fouling, especially if it has a prop ring enclosure.
Drones are the future of warfare so you are a little late to complain about drones being used for warfare. The race is well under way.
“…used by both Russia and Ukraine for surveillance and for delivering bombs, goes for around US $2,000. You can get 55,000 of them for the price of a single F-35”
https://thenewpress.com/books/theory-of-drone is a neat read from the (not that much) earlier period where drone warfare was asymmetric, trying to contextualize it in the broader history of warfare.
It would have to be targeted to the kids with workaholic parents who neglect to spend time with their children, and thus need to spend big to demonstrate that they do, in fact, love their offspring.
The children in question would use the toy for 3 or 4 weeks, get bored of it, and move on.
Notice the cute, baby/pet like music for for tech that will be used by militaries in the near future

This thing would probably be used as loitering munition in swarms and since it's small it might be difficult to hit in urban combat situations.
At least they named it appropriately.
Ray Bradbury's Mechanical Hound has grown wings?

Both civilians and the military already use drones a good amount. Is there anything specific to the military here besides just a better drone?
Came to post this comment and you beat me to it. I think it deserves an overdub with some very intense industrial techno or the Terminator theme.
My suggestion:
Lux Aeterna from Requiem for a Dream, fast forward it about 30s then press play.
The violins kick in just when the logo appears.
Black Mirror episode Metalhead playing on a TV in the background or picture-in-picture would be most fitting, I think.
How about "The Rebel Path (Cello Version)" originally for Cyberpunk 2077 but unused?
Believe by the Chemical Brothers is most appropriate
my exact first thought. black mirror to the soundtrack of a photo app.

Also what if a twig gets in the wheel? Seems like it wouldn’t be able to fly then.

So defense applications with bloated budgets and underutilized obligations to the payee, designed to transfer public funds to private pockets? Got it

I don't see any walking.

clearly you have a strong grasp of the article's content

it's pretty obvious that it can't actually walk.

They should have had the legs extend up and down to prevent scratching the wheels.
For landing I wonder if you could fold the wheels in first and just fall back into driving stance.
Gotta save something for the next iteration, to get the MVP shipped!
Like a machine gun
I can't imagine they'll sell many units without a machine gun.
well, now all it needs is capability to swim and there goes humanity.
Just make the body waterproof, and it will be able to move around in water just fine using the drone propellers.

Caltech developed the first triple-changer Transformer. More than meets the eye!
What is the practical application for robots like these?
It's usually more productive to ask who's paying for the research than to try to answer that question directly.
And the answer for these projects usually: the military complex, possibly through one or two levels of indirection of government/federal grants.
Unfortunately, usually killing people.
Remember people. Robots don’t kill people. Pe— oh wait
Countdown until its made into a weapon.

"Drones are the future of warfare so you are a little late to complain about drones being used for warfare. The race is well under way"
So it's not the future of warfare then by your own words, that's the present situation. What are you complaining about ?
I was thinking more in the direction of a toy for kids aged 8-15.
Those better be some rich kids. 10 year old me would have jump at the chance to tinker with a functional drone like that.
It would have to be targeted to the kids with workaholic parents who neglect to spend time with their children, and thus need to spend big to demonstrate that they do, in fact, love their offspring.
The children in question would use the toy for 3 or 4 weeks, get bored of it, and move on.
We all know these people...
Those things aren't mutually exclusive.
Scale up the rotors, put a gun on it, and bam, fully autonomous mobile artillery!
Scale the whole thing down to the size of a cockroach, and put a poison tip dart on it!
I really hope development goes in this direction. Infantry should be obsoleted as soon as possible.
Infantry soon being obsolete is a way of saying that people will no longer be able defend themselves from near-future weapons
Except with drones of their own.
Any defense over quantities has a statistical nature. You only need to die once.
The biggest/baddest drones will be available to the richest/baddest people, just like all military tech. This is not a great future.
That way all us civilian Zam Wesell wannabes can have a go at it too!
Yep, get rid of the middle man and go straight to autonomous drones killing civilians instead
Add an explosive and it will pursue you. First flying and when you try to hide in a bunker it transforms and rolls on in after you.
Kill all humans?
