The parts of the robot are helpless alone, but as soon as they make the team, they become smart

When you envision a robot, you can shoot from Arsenals to Star Wars or Omnidroid R2-D2 or large armed machines making the assembly line on the assembly line.

But there is a new automated system that is not similar to any of these systems. Instead, some children have forgotten to take their toys.

Android is a collection of Neon Green Plastic Disks. Each of which is about 15 cm (6 in) long. Alone, a single disc can do a lot. It can only expand and shrink.

But when a bunch of discs come together, things change. The small magnets paste them on the outer edges of the disk simultaneously.

When a disk spreads or shrinks, it pushes or pulls its neighbors. All those small payments and withdrawals increase. Suddenly the whole point starts moving – very slowly.

Designers point out that each disc is a “particle”. While working as a system, they become what designers call “gross robots”.

The researchers shared their invention in nature on March 20th. In the new study, he also showed how the particle robot robot can accomplish simple tasks, such as mixing with light.

“This is an innovative system,” says Katja Sikara. He is a computer scientist at Carnegie Mellon University in Pittsburgh, Pennsylvania, who is designing many robotics systems.

Did not work on new inventions. But she says that it shows in different ways how people can build an automated system.

At one end of the robot group, you will find a single-entity device. Think about R2-D2. These robots are only contained in one body.

There are standard robots at the other end of the spectrum. These are the groups of different robots, each of which has its own work, but simultaneously performs a normal operation.

They include “swarm” robots, who talk to each other and share information about where they are roaming.

Sikara says that the new system is somewhere. Discs are individual units, but they come together to form a unified team.

They are treated by their interactions and physics rules, and not by telling anyone

Natural inspiration

Rishta Patra says, “We wanted to make a very simple robot that could respond to changes in the environment.” She is a graduate student at Columbia University in New York City and is part of a multi-university team behind the new particle robotics system.

Petra explains that the scientific nature behind the project was inspired by nature. In the human body, for example, individual cells work together as muscle tissues. Many other cell types also move together as a group.

Robot movement also reminds Petra of something else in the living world. “The point of pulse is fading,” like the Caterpillar movement. “It’s going to walk a little bit, then it goes.”

Although the discs do not communicate directly with each other, they can respond as a set of some signals. Scientists have shown sensor on each disc, which can detect light.

Then they expanded the disk based on the intensity of light and programmed to contract faster or slow.

When the researchers shone in bright light, their robot slipped into it – the result of all those personal expanses and contractions.

To ensure that the group of molecules will not be interrupted, the researchers had to think about how the friction would affect the disc.

Friction is the resistance between rubbing two surfaces simultaneously.

To beat the friction, the disc was hard enough to push. But they could not push each other until their magnets stopped working.

Other challenge researchers had to face to determine the size of the disk. For help, he took refuge in Chuck Huberman of Harvard University in Cambridge, Massachusetts.

When they are thrown into the air and then fall into small balls when caught, then smart plastic toys are tied together.

The new robot team recruited the Hoberman for designing a disc that would produce its “molecules”. Like their bodies, they also become bigger and smaller than the minimum effort.

In the end, scientists had to create a system that could work at different levels. So far, he has created physical robots with more than twenty bullets. But they wanted to show what could be done with a group of hundreds or thousands of particles.

From here, Petra came in. For two years I wrote a computer program in which the behavior of large groups was predicted. I explained how the system with 100,000 particles will run. The program also predicted what would happen if individual discs in the group stopped working.

“It was one of those beautiful things we could see,” she says. “How many of these particles can kill and still move?” Many, as it turned out.

Petra calculated on a robot made of hundreds of thousands – thousands of molecules. Its program predicted that even though one of the five disks has been disabled and the walk stopped, the system would be able to move as a group.
