Miniature robots are the size of human hair and can walk if they are stimulated by laser light.
Miniaturization of electronic products Hair-sized robot This is the goal of the scientific dream, but it is limited due to the lack of a system that operates at the micron level.
Now, according to the magazine naturalFrom University of Pennsylvania, In Philadelphia (USA) managed to get a small team robot To achieve this goal autonomously, they developed a new Electrochemical actuator (The component that makes the robot move) is compatible with silicon electronics. These actuators form the legs of the robot, which are less than the thickness of a human hair and less than 0.1 mm.By stimulating each of the four legs of the robot laser light, Its limbs bend and unfold, producing similar to go.
More than one million walking robots can be produced on a 4-inch silicon wafer, and they are powered by photovoltaic energy from on-board electronic equipment.
The authors of this advancement guarantee that they are the first robots with these features.they are strong They can survive in acidic environments and in the face of large temperature changes.In addition, they can pass Hypodermic needle, Which gives them great potential for research in the biological environment.
However, they also have limitations. As their developers mentioned, they are slower than other existing swimming robots, they cannot perceive their environment, and they lack integrated controls. Even so, they concluded that their compatibility with existing silicon technology should allow further development of their functions.
