Why Robots That Bend Are Better

Robots of the future may be softer, squishier and bendier than robots today. This could make them ideal for space exploration. Check out kiwico.com/Veritasium50 for 50% off your first month of any subscription!
On Thursday February 18th, 2021 the NASA Perseverance Rover will land on Mars. It is a wonderful robot, made out of steel and wire - but will future robots look like Perseverance? There is an emerging field of research on "soft robots", where the machines are flexible. These soft robots have many advantages over traditional robots - they're safer, lighter, more flexible and can change their shape and size.
NASA is investigating the use of soft robots for space missions. For future visits to Enceladus or Europa, a lander could cut a hole in the ice and then insert a compliant robot through the hole. This robot could then grow and change shape on the other side.

  • Typical vacuum tire uses latex-based internal sealant to auto-seal leaks. Also, some vehicles use soft rubber to completely replace air inside tires. Silicone foam resin or something similar can be mixed when the robot deployed, and foam would expand to fill the tube structures. It will be far better than a mere backup pump.

    Max LawMax Law6 timer siden
    • concessions would have to be made in terms of robot maneuverabilty right? the foam is naturally more difficult to compress than air. i think it would be great as a back up system tho, if they could find a light yet strong and elastic enough foam for structural support in those emergency situations, without adding too much weight to the robot.

  • I'm very unimpressed. Other than a few space jobs, I can't see why he is so hyped about them. Rigid robots are the futur, they are not great right now, but once we manage to master their design, they will be much more useful. I'm thinking human shaped robots who can do basic chores which is already in good development, or androids that can do most jobs much further in the futur.

    Micheal DavisMicheal Davis12 timer siden
  • i saw a video where a guy tried to make a thrust vectoring gimble for an rc plane using compliant mechanics, and the problem he had was that the compliance necessary to make the mechanism work also made the mechanism entirely too flexible to handle the thrust it was supposed to be steering. you can say "oh these robots are better because they aren't strong enough to hurt you" but it's still pointless if it's also not strong enough to do anything useful

    • @Ed Purcell I was referring to his last vid with Gates where he said he agreed with Gates that "misinformation" should be deleted and not allowed to be online. This from the guy who did a vid on how many research papers are wrong??? and who gets to decide what is not ok? We still have not seen a retraction or ever a comment to defend the position. So I was just asking, how about this vid. Should some of it not be allowed?

Like Spot from Boston Dynamics was developed and there is some very cool things coming from that now. I love seeing how the construction industry in particular is using Spot.

  • I think the 'why' in the title should be 'when' because 'why' implies, in this instance, they're *always* better which you contradict in the video by saying the not bending variety is more accurate. Or the 'are', which makes the statement sound as if it's true in any situation, could be changed in something like 'can be'.

  • Can't they use the same type of structure/principle that nasa used for it's airless tires? But then it would limit how much its size could reduce, because of the stress limit before permanently bending the metal Could also try doing the same, and using "memory metal"... But then the robot would need a way to keep re-heating it's own "metal fiber tubes" and that would create a power issue
