A team of researchers from Northwestern University in the United States has created the world’s smallest remote-controlled robot.
The robot, which looks like a crab, is so small that even He can walk on the edge of a coin.
Small robots like this aren’t exactly an innovation. Back in 2019, a team of engineers from the University of Georgia created “The Bristle-Haired Minute”, a The smallest robot in the worldThe size of an ant and lighter than a grain of salt.
The novelty of this robot from Northwestern University researchers is that it is remote control. The crab robot can be controlled wirelessly, as the gate writes Gizmodo.
just measure half a millimeter wide It can move at a speed of about half its body length per second. Although it is not an arrow when it comes to speed, its best quality is that it can Move virtually undetected.
In order to be able to build a robot with such miniature dimensions, researchers created it from a shape memory alloy, known by its English designations: shape memory ingot.
This alloy is deformed by a thin layer of glass applied during the manufacturing process, but returns to its original shape when heat is applied.
Thus, a precise laser is used to heat certain points on the robot’s body, and when its various parts deform and bend when heated or cooled, Able to make him walk, as well as turn and jump.
The results of the study were publishedlast week, in the scientific journal robotics science.
