A hopping robot for asteroid exploration
In the SpaceHopper project, students at ETH Zurich developed a robot capable of moving in low gravity environments through hopping motions. It is intended to be used in future space missions to explore small celestial bodies. The exploration of asteroids and moons could provide insights into the formation of the universe and they may contain valuable minerals that humanity could use in the future.
The project began in 2021 as an ETH focusproject for bachelor's students. Now, it is being continued as a regular research project. A particular challenge in developing exploration robots for asteroids is that, unlike larger celestial bodies like Earth, there is low gravity on asteroids and moons. The students have therefore tested their robot's functionality in zero gravity during a parabolic flight. The parabolic flight was conducted in collaboration with the European Space Agency as part of the ESA Academy Experiments Programme.

Asteroids are one of the next big frontiers in space exploration. The SpaceHopper is a small legged robot specifically designed for exploring asteroids. An AI controls the movements of the robot such that it can change its attitude only by moving its legs. Behind the project is a small team of students at ETH Zürich in the final year of their bachelor's degree. As a focusproject, SpaceHopper is...
dope
Mobile Suit Gundam AMBAC system
So cool!
Tolles Projekt! Hoffentlich is einer davon bald auf Ceres, Psyche, oder so. Vielleich wären lange filigrane Beine anstatt hüpfen auch eine viable Option.
I bet rocky would look like this, you know from the book project hail mary
What was the goal? Maintaining position, a specific orientation, getting to a specific position? The research is obviously valid, but the flailing arms are a hazard for anything near it, why reaction wheels were not used instead? Regardless, it was really interesting!!
Looks like some kind of sea creature
weightlessness aint low gravity space
The way I see it, the more robots we can send to space in place of humans, the better.
Also a future where humans just have a bunch of cute, unique robot homies running around seems pretty based and wholesome lol
Whoa
I’m no expert but everything about this design looks wrong. It’s a danger to people and equipment flailing pointlessly. A 4th arm in a tetrahedron would make better sense than a flat triangle. Does it lack eyes and distance detection? Arms that telescope or unfurl would be safer and less destabilizing. Etc. It’s a neat and worthy project - but do better!
Not impressed 😑
Would this be a proven concept of inertial propulsion then?
Put a small gyroscope at the end of each leg that way it can use the gyroscope to right itself easier and manipulate the leg to fine-tune in righting itself.
Reminds me of AMBAC from gundam
It’s so adorable!
We think so too :)
@@SpaceHopperRobotics 👍
They made a robotic facehugger
How do I sign up to experience this!?
Neuralink
Why do this when you can just get the same thing by taping a bunch of cats together?
no cats were harmed in the making of our experiments :)
H O W C A N N A S A H E L P J I N X ?
Half a century we used to go to the moon every couple of weeks, today this 😬
Someone's been reading project hail mary... or was that 5 sided..?
Pretty cool
Agree on the live appearance. To me I saw, an initial panic, the flailing. Then a, ok gotta calm down, it almost relaxes. Tries some moves and adjust as it figures it out.
It looks like when i try and spin myself on the office chair using only my legs, and for that i am proud of the little guy
This was a very cool project, I hope it is worked on further. Calling it now, we'll see something like this on a different planet in the future.
It is built and trained for zero gravity. A planet has gravity. So, no, we will not
seems like the arms can generate forward motion pretty intense
Gyroscopic torque is another methods, one they use on the ISS
I dont thing that robot would work in real zero g
this is real zero g :)
this looks awesome guys
thank you!
How many Cat videos did you guys watch? Every single one of them was worth it. Congratulations 👏🏼.
quite many actually :)
Ziggy Stardust's band is impressed with this.
i see seven future Mark Rober in this video, one just need; a bad day, a brave decision, and an end of the contact, also a lot of viewer, but that's a story for another time.
These guys are all smarter than Mark Rober
dude, i didn't compare the smartness of a person, and most of them would probably loves their work so it's fine. what i mean is one (or two) of them could be famous, become an inspiration of millions of kids, helping disabled people, and make their own company, because we love the company~ the company~ the company~ we love the company~ and the company loves us~
I'm worried about robots and possible AGI or more. So please don't teach them how to move in space, if it goes wrong on earth and we do lose control they gotta stay here, not floating all over the galaxy😂
Adding dramatic music isn’t always a good thing. This video would be better without it.
Ok, but why..? Are there no more efficient ways to move in space?
This IS a more efficient way to move in space
Absolutely phenomenal stuff. This is what Robotics should be used for!
A valiant effort! I would rather use shrouded fans mounted on different sides. It provides much more stable and predictable motion. Using horizontal or vertical slats that can be angled to provide vectored thrust. I think this has already been done in space if I remember correctly.
Reminds me of a Scrambler from “Blindsight”
Super cool! What you guys learned from the flight ?
This is real spaceengineers stuff there :O
Love that
Alternatively, just use a Control Moment Gyroscope like satellites do and use simpler arms to push off of surfaces, couple with fans given operation in an atmospheric environment (space station), or with reaction thrusters for big movements in open space… Far less development cost & uncertainty, more predictable kinematics, and more predictable movement patterns given you wouldn’t then need to make the thing flail its arms to reorient. Cool concept and integration and I always will applaud applied engineering skills but this is better in a sci-fi book than it will be practical compared to existing technology. There’s a reason satellites don’t use jointed arms for moment control, and rovers don’t use arms to crawl like Rocky from PHM. My college satellite team in the US developed its own cubesat-scale Control Moment Gyroscope for less than about €1,000 when I was in uni (provided access to CNC). Seems like a lot of engineering and very expensive testing to replace a more efficient technology.
The robot is designed for controlled low gravity locomotion, such as on asteroids or moons. It uses its legs to jump to a new desired position. Since it has legs anyways and we want to minimize the size, weight and complexity of the system, we omit gyros and use the legs for attitude control.
@@alexanderspiridonov4353 I read the caption and I understand the purpose of the robot but what I’m saying is this is an inefficient way to go about solving the problem. The space station stuff I mentioned was hypothetical, but in terms of the quoted purpose: First off, you can’t tell me honestly as an engineer that size and weight are a limiting factor to implementing a CMG when 2u cubesats have similar systems. Our CMG was ~1u and <400 grams, with off the shelf solutions being 0.5u and 300g. Yeah, CMG’s are relatively complex (mechanically) but they’re also industry standard and well-known in the world of engineering for a reason. If a space agency is spending billions to explore an asteroid or moon, they’re going to pick that industry-standard time-proven solution every time and then some. Especially when it is an autonomous vehicle. This is a tough-learned lesson in the world of engineering but it’s simply the truth (yes I know your research is being sponsored by one). You’re correct about complexity rather than size & weight, but even then this solution introduces more complexity to the involved physics and physical attitude adjustments than are present with a CMG Second, in proper low-gravity environments this concept simply isn’t going to stay planted on the surface of the object without some sort of CMG or even thrusters for attitude control (which weigh more than a CMG)- the necessary kinematics will be too chaotic to quickly correct attitude and the robot will either fly away or crash into the surface. I’m sure you’ve done simulations on this. It’s a nice idea but in an autonomous operation regime it’s going to have problems that would be mitigated with a more traditional solution using a CMG, namely speed and predictability of attitude adjustment. Using flailing legs for attitude control is not ever going to be optimally-efficient for these reasons (power as well) and there’s a reason this hasn’t been done with asteroid sample collection, exploration of other planets, or exploration of our own moon. You still would need arms but like I said, this is an unnecessary hoop to jump through for no reason when a CMG would do a flat out better and more stabile job at attitude control for an autonomous robot on a low-g surface than using the arms- I think it would make the desired hopping much more controllable, fast, and efficient without a big trade-off in terms of weight. I’m not saying the hopping motion isn’t a great way to explore such a surface (I think it’s cool), all I’m saying is you should explore adding CMG’s to make executing that motion on the surface of an unpredictable asteroid or moon more predictable and stable; it’s not going to add too much weight or size. CMG’s weigh 1-5% the total weight of satellites, and come as small as 0.5u for cubesats off the shelf
Different technologies for different purposes.
@@party4keeps28 Not really how engineering works; you can’t boil down design decisions to a statement like that. It needs to be quantified, weighted, analyzed for failure modes, tested, and evaluated. Either way, that statement would prove the point that using different technology (arm movements) than industry standard (CMG) to adjust attitude in a (flying or in this case hopping) spacecraft is not apt
@@Laminar-Flow In relation to your first paragraph, that's EXACTLY what they're doing. If everyone had your mentality and stuck with the "industry standard," we'd never get anywhere.
The bit you want to see: 2:16
Nice video. Cool experiment. Are the legs really better than reaction wheels?
JINX!
These guys look young. I’m rooting for them and the future.
Thank you!
wind resistance?
Wind resistance in a vacuum?
well...maybe in the plane since its not a perfect model but I doubt is a problem in space most of the time, however there is thermal/solar wind!
Really cool to watch
It doesn’t look ,like it’s doing anything
It may be a bit confusing because the commands are randomized, but the robot changes its attitude to commanded orientations using its legs, and jumps to commanded velocities.
Looks pretty active in orienting itself to me. Seems to be able to perfectly align itself with anything around it in a second, even humans would struggle to do that without using a grip on something solid.
Lowkey looks like magic. It flails its legs around and all of a sudden floats in a direction. Insane
@@boombox789 I believe they just made this up so they could ride the zero-g
@@scottw595 haha This hadn't occurred to me but it makes a lot of sense. The plane tickets probably cost a lot less than that robot cost to build though
