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.

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.

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).

*Many robots (including soft robots) are programmed for locomotion and other forms of motor control based upon the wiring principles of central pattern generators* (CPGs)—neural circuits that produce a wide frequency range of oscillatory rhythmic outputs even in the absence of sensory feedback—that have been adapted by evolution over hundreds of millions of years across the animal kingdom for axial, quadrupedal, and bipedal locomotion, as well as many other peculiar forms of locomotion, including rolling locomotion akin to that of the robot showcased in this video here. After several months of preparation, I'll soon be posting vids from my perspective as a Harvard neurobiologist and scientific editor/consultant. Cheers.

So, at what point does the charge chose to produce the magnetic field. lets say normaly u pass a current through wire, it produces a magnetic field, but if you were to move along with the charge, would it produce any magnetic field.

@Oxy Bright Dark But those big spinning devices are on earth where there is already gravity-the centrifugal force then works towards the circumference of the device.i dont get how centrifugal force would work where there is no gravity. The people in the space station (or whatever) are not held to the surface of the thing that is spinning unlike the example of water in a bucket?

If you spin a bucket round and round, the water contained won’t fall out, because it’s sent constantly backwards into the bucket, rather than into the earth. Centrifugal force, which is actually a combination of forces, would work in space. But when you go towards the middle of the ship, it’ll spin faster and the gravity would be stronger. This means that the ship would need to be quite big, and the middle compartment not liveable, or in the shape of a donut or frisbee, spinning so that the outside is faster. They use big spinning devices to test G forces. Tom Scott made a video about it.
