New robots called Cross-Link Collective didn’t use commands for self-organization.

“Robot swarm self-organizes into flowing chains without centralized control.” (ScitechDaily, ‘Like a flowing material’: Robot swarm uses physics, not commands, to self-organize)

There is a possibility. To use Velcro hooks to destroy the bacteria. The bacteria pull the particle. That. It thinks.  As food. Inside it. Then the chemical environment straightens the Velcro hook.  That damages the protein shell. Of the bacteria. The system uses a thing called mechanical memory. This means that the structure can repeat backwards. An every single turning. That the user makes for it. 

A robot swarm that used physics, not commands, for self-organization. That makes it possible to create structures that can act like an amoeba. The miniature robots can make things like liquid robots. That can change their form like T-1000. In the Terminator movies, reality. Those small robots can carry microchips. Inside them. 

“Researchers say the robots rely on 'mechanical intelligence' instead of advanced computation or communication systems. Their physical interactions allow coordinated movement to emerge naturally as the modules continuously connect and disconnect while moving.” (ScitechDaily, ‘Like a flowing material’: Robot swarm uses physics, not commands, to self-organize)

Those robots don’t need centralized commands. But they can carry microchips to targeted points. 

“The system, called the Cross-Link Collective, is made up of dozens of narrow robotic modules that can latch onto one another using weak Velcro connections. Individually, the robots move slowly and struggle in difficult terrain. But when linked together, they begin acting as a coordinated collective capable of navigating obstacles and inclines.” ScitechDaily, ‘Like a flowing material’: Robot swarm uses physics, not commands, to self-organize)

Those robots were made by researchers at Cornell University. Their size is quite big. But their nano- or minisize colleagues. Can raise medical treatments to a new level. 

The self-organizing robots can make many things. They can clean surfaces. They can remove dangerous organisms. And those systems can replace chemical weapons. 

There are plans to use. The DNA-controlled nanomachines for making structures through self-organization. The microchip-controlled system can select the DNA sequence that the nanomachine reads. And then those systems can get any form. Those cyborg amoebas can make impressive things. They can slip into the houses. And those systems can read information that travels in cables. 

Nanorobots can block leaks in fuel lines. They can also assist surgeons. And they can block blood vessels that transport nutrients into the cancer. This means that nanorobots can block blood vessels. Or they can simply fill the targeted cells using nanomachines. 

The mechanical intelligence causes that. When the nanomachine slips into another chemical environment. That thing makes the robot change its form. 

“Each robot measures roughly 200 millimeters long and 20 millimeters wide. A small internal motor drives the module to repeatedly switch between an “I” shape and a “U” shape, creating forces that push it forward across surfaces. Weak Velcro patches at both ends allow nearby modules to temporarily attach and detach as they move.”  (ScitechDaily, ‘Like a flowing material’: Robot swarm uses physics, not commands, to self-organize)

Their size. It is so big that they can make many other things. Than just. Blood vessels. They can operate on a larger scale in structures. Like fuel tanks. 

But it’s possible that those robots can make many other things. They can block blood vessels. And they can close the blood leak. And the same ability that makes those systems excellent medical components makes them the worst weapon that we can imagine. The same system. That can block the blood vessel. This transports blood into damaged tissue. It can also block blood vessels from enemy operators or a person. 

Targeted for assassination. Unlike the poisons. Nanomachines are chemically neutral tools. They can hide in margarine. Or some oil. Their effect is purely mechanical. So, that thing means. Those sensors and dogs don’t see those tools. The nanomachine can slip the oil droplet into the bacteria. They can destroy bacteria by covering their mitochondria. Using oil droplets. Those things deny the mitochondria's operations.
