The magnetic coating gives energy to new millirobots

The new nano- or millimeter size drones are fascinating tools for many things from natural or medical research to recon and intelligence work. They can slip in the nests of bugs like wasps and search, what those animals are doing. They can slip in buildings and then make observations of the things, what they are seeing. Millirobots can look like worms, but they can be like regular quadcopters. But millirobots are just smaller than regular quadcopters. The millirobots can swim in human veins as well as they can swim in the ocean.

The millirobots can also form intelligent or independently operating entireties by connecting themselves to the large entirety. Those robots might communicate with each other, and they can deliver to some areas from aircraft or even from satellites.

And those millirobot systems can slip into the human body and search and remove bacteria or tumors. They can search for chemicals or people from large areas. But the sad thing is that the same systems, that can remove tumors can simply make aisles in the blood veins or brain tissue.

The millimeter-sized robots can also fly around the target and point the microwaves in the same spot, which causes an electric arc in that point. Those robots are like dust, which can have many opportunities in the civilian and military areas.

One of the biggest problems for those miniature robots is how they get electricity. One of the answers is to deliver electricity for those robots is to use high-power radio impulses, but that thing requires the open area, where the radio impulses can target. Those radio waves can load the batteries of the drones. And the radiowaves what is giving electricity for those drones can deliver by using radars or other radio transmitters.

This kind of system might deliver energy to the millimeter robots, which are operating in short distances. But how to deliver energy to the robot, what operates in long distances. Another thing is how to get the data from those drones?

One of the answers is that another radio transmitter will send radio signals through the drone swarm, and that thing will act as the carrier wave. When the data is transmitted inside the radio beam, that thing makes it easier to detect in longer distances.

But how the millimeter-sized drones can operate independently by using an internal power source?

How to miniaturize a generator that can deliver electricity for miniature drones? One of the answers is to use the gyroscope, which would rotate the miniaturized generator. The problem with the gyroscope is how to put that thing rotate? One version of the system, which delivers energy for the nano-size drones could be the capillary tube or hollow fiber, which pulls the air through the small turbine wheel.

The problem with regular batteries is the short operative time. The answer could find from the mechanic clocks. The small-size flywheel is giving the power for the machinery of the clacks. So a similar system can give electricity to miniaturized drones.

The flywheel can rotate in the box, and give electricity to the milli-robot by rotating the small size generator. Or the wheel can itself operate as a generator. The flywheel can be in a small chamber. And the magnetic core of the robot can give electricity to the small-size system.
