Northwestern University engineers have succeeded in Create a robot the size of a penny in the shape of a crab. It is the world’s first smallest remote-controlled walking robot, and these tiny crabs, taking shape, are capable of Bending, twisting, crawling, walking and even jumping. The team also created millimeter-sized robots that resemble crickets, worms, and crickets.

Although the research is still in its early stages, it is hoped that this technology will be useful Approaching the development of small robots capable of carrying out practical work in confined spaces. The robot does not work with machinery, plumbing, or electrical systems. Its strong point is undoubtedly Flexibility and flexibility of the body.

Science, the world’s smallest remote control walking robots

The researchers used to build it Shape memory alloy materialWhich, when heated, transforms into the shape it remembers. In this case, use Scanning laser beam to heat the robot in different parts of the body. Once cooled, a thin layer of glass returns the distorted component of the structure to its original shape. When heat is applied repeatedly in a certain sequence, Crabs were able to move, similar to how humans bend and straighten their legs to walk.

robots The exciting field of research and development of micro-robots is an interesting topic for academic exploration. We can imagine precision robots as agents for repairing or assembling structures or small machines in industry or as surgical assistants to remove clogged arteries, in order to Stopping internal bleeding or eliminating tumorsAll in innovative, minimally invasive procedures. The technology also allows for a variety of controlled motion modes He can walk at an average speed of half his body length per second. It is very difficult to achieve this on such small scales of terrestrial robots.

Motion is generated when the robot passes from one stage to another: from a distorted shape to a retrieved shape and vice versa. The laser not only activates the robot from a distance, but the scanning direction of the laser also determines the direction of its movement. To do this, the researchers created flat and flat antecedents for the moving crab constructs. A controlled deformation process occurs when the tensioned substrate is loosened, This causes the cancer to appear in precisely defined three-dimensional formations.
