Description

The human body is composed of many narrow, winding passageways and impenetrable obstacles that are difficult for any robot visible to the naked eye. However, over the past few years very small robots have been built that can penetrate any small space and tightness.

However, these robots have less capacity to carry the materials needed to patients' internal organs because of their very small size. But a robot capable of deformation can overcome this problem by becoming a group and then recombining.

In their new study, a team of international scientists built a robot from Ferrosial, a colloidal mixture of iron oxide and hydrocarbon oil. They have used spherical and rotating magnets to force matter so that the robot can be divided into many pieces or stretched to move through narrow passageways.

To demonstrate the potential application of this robot in passing through the arteries and capillaries of the human body, researchers have built a thousand with large and narrow parts. As shown in the video of this report, the robot can successfully reach the end of the maze by splitting into smaller groups.

Scientists explain that the barrier to their way to use this invention in biomedical applications is a magnetic control system that must be strong enough to penetrate human tissue.

In the past decade, researchers have used emerging magnetically controlled microbiota technology in the field of human health care more than ever. The next big change in this area is the construction of small robots of liquids, gels and elastomers, which have a very soft and flexible body and are more flexible than robots made of rigid materials.
