The internationally renowned academic journal "Nature" recently published an electronics research paper describing the birth of a walking miniature four-legged robot with a million troops. This achievement benefited from a new type of actuator compatible with existing silicon electronic devices. The development of (parts that make robots move).
The corresponding author of the paper, Marc Miskin of the University of Pennsylvania and his colleagues showed a new type of electrochemical actuators. These new types of actuators constitute the legs of the robot with a size of less than 0.1 mm (about the size of a human). Hair width), when stimulated by laser, it will bend and produce walking motion. They have manufactured more than 1 million walking robots on a 4-inch silicon wafer, which are powered by on-board silicon solar cells. These are the first known robots with a size of less than 0.1 mm, which brings the possibility of exploring applications in biological environments.
The video shows a miniature robot in a circle. The movement of the robot can be changed by changing the style of the rigid panel. Here, the retreat rotates slightly relative to the body of the robot, making the robot walk in a circle. The video is 8x speed.
