Why running robots cannot reach the fastest animals?

"A study reveals that engineered components in robots frequently surpass biological equivalents, but animals outperform robots in overall system functionality, pointing to integration as the key area for robotics improvement.

When we want to make a fast robot. That walks like a human on the ground, we must observe how fast animals make their thing. The easiest way is to make a mechanical robot that imitates fast animals like cheetahs or kangaroos. Then we must make a robot that moves like those animals. A robot that runs like a human cannot reach a cheetah.

In the case of the cheetah and other four-leg animals the thing. What makes the cheetah run so fast is how many touches their feet touch to the ground in the time unit.

Also, the power of the punch determines how fast animals can run. The other thing is that this big cat's entire muscle system gives a punch in that process. The cheetah's front feet touch the ground at different times. That maximizes the contact time with the layer. And that time determines its speed. Only when the leg touches the layer. It gives speed to that animal.

Cheetah uses a very much energy while it's running. And it can keep its full speed for only a short time. So if we want to make a mechanical Cheetah, that moves exactly like a natural cheetah, we must make sure. The robot makes everything like a Cheetah or horse. While a horse runs, it moves only its feet. That makes its run more economical.

The robot can look like a car. It can have four legs that involve a similar touching system. That makes ibexes impressive climbers. The robot can change between legs and wheels.

In the robot world nature gives no limit for productivity. That means engineers can make four-legged robots that have hands, and they can also walk on two legs. But the two-legged robots also can move very fast. The robot can start to move by jumping, like rabbits and kangaroos. Those robots can also start to use wheels when they must travel fast.

The wheels can be like roller skates under its feet. Or wheels can be at the hippie. The robot can use the wheels. Which they can pull in. Those wheel's perimeter can be segmented, which allows the robot to pull them in. The large-size robots can also use feet, that they can turn into cargo positions when they start to use wheels.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
