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.

    Veritasium Can you do a video on why hands smell burnt if rubbed together fast (or comment?)? Surely my hypothesis would be that the friction generated heat does indeed burn skin cells, but only the superficial, first layer of cells in the stratum corneum. So the superficial layer gets burned off, but because that first cell layer is so thin, the heat is quickly diffused into the rest of the layers and the air, so it only feels warm, not really hot. Iwasnt able to find any info on this myself, so Id appreciate your imput. Im curious lol

    After talking about the under water exploration I was thinking that you could fill the tubes with water. Then I thought that instead of a rowing motion, instead use a fabric that when rolled through the motors would pull itself through the water. You would have to rotate the tubes into a 3 sided pyramid and have the return part of the tube be blocked by say a corner cone.

    Do a video about where time passes the slowest. If we lived near a black hole, like in Interstellar, time would pass a lot faster. A civilization in the slowest ticking time, would have more time to advance and survive to the end of the universe compared to one living near a black hole. Is the edge of the galaxy the place where time passes the slowest?

      That's a question that could have a variety of answers and is unclear with a lot of guess work. Could be the shape of the cup how its dropped to the pressure of the air trapped inside the cup when it seals the rim with the water and wants to continue sinking. It's most probably the compression of the air trapped trying to escape forcing the cup over sideways and then finding its resting point then all the forces come to equilibrium.

    All this is interesting, but there are more interesting things. Modern ideas about the universe are too superficial. For just one billion euros, I am ready to tell everyone interested how the universe was actually born and what matter is made of. And also, what is wrong with the Einstein formula (A. Poincare) and how to overcome the speed of light using a reasonable supply of energy. I almost forgot why all the measurements of the speed of light carried out so far cannot be considered correct and why different photons must have different speeds, the speed of light is not a constant. And also, why black holes are black (hint-the reason is not that light can't escape because of gravity, everything is more complicated here).

      Tether two clocks to a central anchor with two equal and known length...tethers.. Move both the clocks in opposite directions until they reach the limits of the length of the tether. These clocks are designed to begin when they detect a certain (sudden and reducing) change of tension in the tether. Destroy the central anchor.

      I propose accelerometer or tension clocks. Timers that start when they undergo a certain change in motion or change in tension of a tether.
